Comprehensive Study Notes on Christianity: St Paul, Environmental Ethics, and Baptism
Contributions of St Paul of Tarsus to Christianity
Overview of St Paul's Significance:
The contribution of Paul of Tarsus to the development and expression of Christianity was immense and second only to that of Jesus Christ.
Background & Education: Paul’s education as a Pharisee provided him with an excellent rabbinical and scriptural background for writing, speaking, and debating. This prepared him ideally as the church’s greatest missionary and apostle of the Gentiles, highlighting his inclusivity.
Conversion & Transformation: Paul’s conversion shows that redemption is always possible. His transformation from a persecutor of Christians to a devoted apostle highlights the power of faith, grace, and hope. These values, central to both Jesus' teachings and Paul’s mission, serve as guiding principles for adherents.
Four Core Areas of Contribution: Paul’s contribution pertains to four main areas: his Missionary Work, his Writings, his Theologies, and his Leadership.
1. Missionary Work - Spreading the Gospel:
Role as Missionary: Paul was the most effective missionary of the early church, making an enormous contribution by influencing every era and aspect of Christianity.
Missionary Journeys: Supported by Jesus’ last instruction to go and spread the Good News to the whole world, Paul undertook 3 major missionary journeys, recorded in the Book of Acts.
Establishment of Early Churches: Paul established churches in political and cultural centres of the Western World (such as Rome, Antioch, Ephesus, and Corinth) based on his understanding of Jesus’ beliefs and teachings, thereby increasing the chances of survival for early Christians ("So the Churches were strengthened in their faith and grew daily in their numbers." - Acts 16:5).
Expansion Beyond Judaism: An encounter with the Risen Christ convinced Paul of the need to expand the message of Christ beyond Judaism to all peoples, including Gentiles and pagans.
Council of Jerusalem: Paul addressed the relationship between Jews and Gentiles in the Christian community. He advocated for Gentiles at the Council of Jerusalem, addressing circumcision, kosher laws, and morality. His efforts helped establish Christianity as a religion in its own right, not merely a sect of Judaism, making it accessible to non-Jews and causing a rapid expansion of Christianity.
Emulating Christ's Justice: Paul modelled the way of Christ by responding to issues of injustice, such as the famine in Jerusalem. He insisted on weekly monetary collections ("a sum of money in keeping with your income" - 1 Corinthians 16:2), a tradition that has continued in the Christian church.
2. Writings:
Primary Source of Christian Beliefs: Paul was a prolific writer in the New Testament. His writings were a major contribution to the development and expression of Christianity as a primary source for Christian beliefs. He linked these principal beliefs to key Christian practices: Baptism and Eucharist.
Contribution to Sacred Scripture: Paul contributed to more than 1/4 of the New Testament scriptures with his letters (Pauline Epistles), which are considered part of the sacred writings of Christianity bearing God’s authority. Paul stressed that he was teaching the gospel that Jesus and God the Father revealed ("I did not receive it from any man, nor was I taught it; rather, I received it by revelation from Jesus Christ" - Galatians 1:12).
Guidance to Mediterranean Communities: Paul’s letters provided foundational guidance to early Christian communities, directing them to overcome theological concerns and instructing adherents on how to live a Christian life in the varied cultures of the Mediterranean.
Teaching on Agape (Selfless Love): One of the most important teachings evident in his writings is the concept of agape (selfless, unconditional love) in 1 Corinthians 13:1 ("If I speak with the tongues of men and of angels, but have not love, I have become a noisy gong."). He emphasized the importance of love, unity, and the operation of spiritual gifts within the Christian community. His teachings continue to enrich faith and affect Christian ethics.
3. Theologies:
First Theologian of the Church: Paul was the first theologian of the Church, helping to explain and shape what Christians believe. His writings (such as Romans, Corinthians, Galatians, and others) are foundational to Christian theology, teaching Christians about God, faith, and how to live as Christians. He addressed theological issues including the nature of God's grace, salvation, and Justification by Faith.
Grace and Salvation: A central aspect of Paul’s theology is his understanding of grace, salvation, and justification by faith. Paul taught that salvation is a free gift from God, offered through divine grace and received through faith in Jesus Christ, not through human effort. This reflects the teaching of Christ in John 14:6 ("I am the way, the truth, and the life. No one can come to the Father except through me."), affirming that Jesus’ death and resurrection are the source of salvation for all believers.
Justification by Faith: Paul further developed this doctrine by emphasizing that salvation comes through faith in Jesus Christ rather than following laws or rules, making it a universal faith accessible to all people, both Jews and Gentiles ("For it is by grace you have been saved, through faith… it is the gift of God— not by works." - Ephesians 2:8-9).
Analysis of the Impact of St Paul on Christianity
Impact of Missionary Work:
Global Development: Paul’s missionary journeys are responsible for the development of Christianity in the early centuries and to this day, as Christian communities of many different denominations still exist all over the world.
Preventing Sectarian Isolation: Without Paul, Christianity may have remained a sect of Judaism (decided at the Council of Jerusalem, 49 CE). Paul added a universal character to Christ’s message, especially for Gentiles who had not heard the Good News of Jesus Christ.
Internal Transformation & Inclusivity: His journeys highlight the change that occurs internally when a person converts to Christ: "Gentile or Jew, slave or free, woman or man – no more" (Galatians 3:28). This serves as a model for contemporary religious dialogue—both interfaith and ecumenical—and understanding among diverse religious communities.
Contemporary Papal Leadership: Pope Francis advocates for inclusivity, urging Catholics to welcome different cultures and engage respectfully with non-Christians. He stated in The General Audience (2019) that resolving Christian issues means embracing dialogue, listening patiently to one another, and listening to the Lord’s voice, as modeled in the Council of Jerusalem.
Earliest Written Testimonies: Paul’s missionary journeys and letters are the earliest written testimonies to Jesus ("Laid a foundation…and that foundation is Jesus Christ." - 1 Corinthians 3:10-11). This emphasizes how Paul not only shaped Christianity but directly impacted and guided all adherents in emulating the model Jesus set.
Impact of Writings:
Liturgical Practice: Paul’s impact is evident in the Acts of the Apostles and his 13 letters, which are used today as holy law/teachings, particularly in Saturday/Sunday worship. His letters helped, supported, encouraged, and inspired all variants of Christianity, showing a lasting impact on the style and structure of worship.
Marriage Ceremonies: The longevity of Paul’s influence is clear where his teachings on selfless love in 1 Corinthians 13 continue to be read at marriage ceremonies, encouraging Christians to emulate the selfless and patient love of Christ in relationships.
Modern Application via Dilexit Nos (2024): The impact of Paul's teaching on agape is reflected in Pope Francis' 2024 encyclical Dilexit Nos ("He Loved Us"). Quoting Romans 8:37, it reinforces that nothing can separate believers from God's love. The encyclical encourages Christians to embody selfless love in daily life, following Paul's teachings to combat modern challenges like consumerism and disconnection.
Impact of Theologies:
Source of Church Renewal & Protestant Reformation: Theologians such as Martin Luther and John Calvin drew heavily from Pauline theology, shaping key Christian doctrines. Paul's letters, particularly his teachings on Justification by Faith (Sola Fide), profoundly impacted both reformers. Luther, inspired by Romans 1:17 ("The righteous shall live by faith"), used this principle to justify his break from the Catholic Church, laying the foundation for the Protestant Reformation.
Addressing Contemporary Social Issues: Paul’s theology provides spiritual renewal to contemporary Christians facing social injustice, inequality, and violence. Christian organisations actively draw on Paul’s teachings to advocate for peace, unity, and compassion.
The Salvation Army: Continues to support marginalized communities, embodying Paul’s virtues of faith, grace, hope, joy, and love in practical ways.
Pope Francis (Fratelli Tutti): In his Fratelli Tutti encyclical, Pope Francis echoes Paul’s emphasis on unity and fraternity, urging Christians to "forbear one another in love" to overcome contemporary adversities like global conflict and division.
National Council of Churches in Australia (NCCA): Inspired by Paul’s emphasis on unity and the belief that believers collectively form the Body of Christ, the NCCA brings together different Christian denominations to promote dialogue, cooperation, refugee support, and environmental stewardship.
Australian Inclusivity & Reconciliation: Paul’s theology provides spiritual renewal to contemporary Christians in Australia through teachings on Justification by Faith and unity in Christ. Many Australian churches emphasize Galatians 3:28 ("There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus"), inspiring inclusivity and social justice initiatives such as refugee support programs, Indigenous reconciliation efforts, and interfaith dialogue.
Christian Ethical Teachings on Environmental Ethics
Overview of Environmental Ethics:
Environmental ethics attempts to define a system of values that guide human interaction in the modern world, particularly in relation to the natural environment.
The world and humanity are interrelated through God’s creation; respect for creation stems from respect for human life and dignity.
Its role is to proclaim moral values and to educate people in ecological awareness.
Humanity’s obligations regarding stewardship mean adherents are carers, not owners, of the environment. Caring for the earth is a moral imperative and a matter of justice.
Environmental ethics are derived from the Old Testament (Genesis) and New Testament (Jesus’ parables and miracles).
Christians are called to emulate the actions and teachings of Christ by responding to the needs of the earth.
1. God is the Creator of the World, & All Creation is Made in the Image of God:
Explanation: God is the creator, and man is His image-bearer and steward. All of nature, including man, is equal in its origin. Nature has value in and of itself because God created it.

Significant Practice: Baptism
Description of Baptism:
Baptism is a significant practice and a rite of passage marking the initiation of a person into the Christian community.
It is considered a sacrament in most churches and an ordinance (rite/ceremony/service) in others (such as the Baptist Church). It is the sign of new life through Jesus Christ and a necessary element for Salvation in most denominations.
Denominational Exceptions: Quakers and The Salvation Army DO NOT see Baptism by water as necessary, believing saving grace (Salvation) comes from God as a result of faith.
Baptism allows Christians to share in the death and resurrection of Christ and cleanses adherents from their sins. In an address in St. Peter’s Square (Jan 2020), Pope Francis proclaimed: "In asking to be baptized, Jesus exemplifies the Christian calling to follow along the path of humility and meekness."
Types of Baptism:
Immersion: Being completely submerged into water, emphasizing the connection to Jesus’ death and resurrection (favoured by Pentecostal Churches).
Aspersion: Sprinkling of water three times to symbolise the Trinity.
Affusion: Pouring of water, connecting to purification or the transmission of the Holy Spirit.
Timing of Baptism:
Infant Baptism: Practiced by Anglican, Catholic, and Orthodox churches. Parents and Godparents make commitments on behalf of the child to nurture them in the Christian faith.
Believer Baptism: Practiced by Baptist, Adventist, and Pentecostal churches. Infant Baptism is not accepted; adherents choose to be baptised as adults after making their own decision to repent and be born again.
Ceremonial Structure:
Welcoming rite
Questioning of parents/sponsor
Signing of the child or adult on the forehead with the Sign of the Cross by the priest/minister
Celebration of the Liturgy of the Word
Exorcism, followed by anointing of the child/adult with oil
Blessing of the baptismal water
Parents' renunciation of sin and profession of faith
Baptism in the name of the Father, Son, and Holy Spirit, and anointing with oil
Clothing with a white garment and the giving of the candle
Conclusion with the Lord’s Prayer and final blessing
Expression of Christian Beliefs Through Baptism
1. Death & Resurrection of Jesus Christ:
Belief Explanation: The baptized crucify their old life and rise to a new faith in Christ, participating spiritually in the mystery of Jesus' death and resurrection.
Sacred Text: Colossians 2:12 — "for when you are baptized you were buried with Christ and Baptism you also rise with Christ"
Symbol & Ceremonial Ritual:
Baptismal Candle: Lit from the Easter candle, signifying the light and life of Christ brought into the world of the newly baptized in the hope of inheriting eternal life.
Water: Reflects rebirth and cleansing from sin. Full immersion and rising again in Orthodox and Pentecostal churches is a physical expression of Jesus' death and resurrection, freeing humanity from sin and introducing a new way of living.
Significance for Adherents: Represents a fresh start and the beginning of a new life with Christ. Adherents become part of the faith community and share in Jesus’ victory over sin and death. Example: In June 2022, 265 women in a correctional facility in Denver were baptised by pastors from Red Rocks Church, offering spiritual renewal, connection to Jesus’ resurrection, and redemption despite serious past crimes.
2. Salvation:
Belief Explanation: Baptism is a rebirth from original sin into the life of the Spirit. It is viewed as spiritual cleansing and renewal announced by Jesus as necessary for salvation.
Sacred Text:
John 3:5-6 — "Jesus answered, 'Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit.'"
Galatians 3:27 — "For all of you who were baptized into Christ have clothed yourselves with Christ"
Symbol & Ceremonial Ritual:
Water: Immersion, affusion, or aspersion during Baptism serves as a "spiritual circumcision" where sins are "cut away" (Paul of Tarsus). It symbolizes God’s desire for individual salvation, divine life, grace, and new birth.
White Garment: Symbolises the purity of the 'new' Christian, expressing that the individual is cleansed from original sin.
Significance for Adherents: Pope Leo XIV stated that "Baptism is the gateway to Christian life." Through Baptism, adherents reject sin, accept salvation through Christ, and begin a life of discipleship. At the Easter Vigil, Christians renew their baptismal promises, reaffirming commitment to the Gospel.
3. The Nature of God & The Trinity:
Belief Explanation: Fulfills God's will and commandment that adherents be baptised or filled with the Holy Spirit, reflecting Christian belief in a Trinitarian God (Father, Son, and Holy Spirit).
Sacred Text: Acts 2:38 — "Peter replied, 'Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit'"
Symbol & Ceremonial Ritual:
Sign of the Cross: Made on the newly baptised person’s forehead while the words "I baptize you in the name of the Father, and of the Son, and of the Holy Spirit" are spoken during pouring or immersion (Orthodox churches immerse the infant 3 times for the Trinity).
Oil: Anointing with sacred oil (Catholic, Anglican, and Orthodox) symbolizes healing and strength provided by God through the gifts of the Holy Spirit (known as chrismation in Orthodox Churches). The World Council of Churches affirms: "God bestows upon all baptised persons the anointing and the promise of the Holy Spirit".
4. The Church as the Body of Christ:
Belief Explanation: The Church is the Body of Christ, and membership into this Body is achieved through Baptism. Adherents believe they are baptised in the Spirit into one Body.
Sacred Text:
1 Corinthians 12:13 — "For we were all baptized by[a] one Spirit so as to form one body—whether Jews or Gentiles, slave or free—and we were all given the one Spirit to drink."
Ephesians 3:17 — "Christ will make his home in your hearts as you trust in him. Your roots will grow down into God's love and keep you strong."
Symbol & Ceremonial Ritual:
Gathering of Community: Parents, godparents, and the congregation gather, recognizing that all are created by the same God and made members of the same Body of Christ.
Proclamation of the Word: Enlightens candidates and community with revealed truth, making Baptism the "sacrament of faith" and sacramental entry into faith.
Analysis of the Significance of Baptism
Significance for the Individual:
Beginning of a New Life (Linked to White Garment): Joins the adherent with Christ in a life of service that shares in His victory over sin and death. Grants access to other sacraments (Eucharist and Marriage in Catholic, Orthodox, and Anglican traditions), providing a sense of belonging to the Body of Christ.
Strengthens Relationship with God (Linked to Water & Death/Resurrection): Fosters greater understanding of Jesus' sacrificial death, strengthening faith and calling adherents to ministry in daily life. Guides adherents to resist sin ("Do not offer any part of yourself to sin as an instrument of wickedness, but rather offer yourselves to God" - Romans 6:13) and regularly seek reconciliation through prayer and confession.
Salvation & Obedience to Christ's Command (Linked to Salvation): The Holy Spirit enables adherents to emulate Jesus by living out the gifts and fruits of the Spirit in daily moral decision-making. In a 2019 sermon, Anglican Archbishop Justin Welby stated: "Baptism is not an end in itself, but a means to an end. It is a symbol of our new birth in Christ." Baptism constantly reminds adherents to embrace mercy and peace by advocating for marginalised communities.
Significance for the Community:
Sense of Belonging (Linked to Body of Christ & Gathering): Entry into the Church through God's saving action marks spiritual development, reflecting 1 Corinthians 12:13 ("For we were all baptised by one Spirit so as to form one body…").
Creation of a Shared Identity (Linked to Proclamation of the Word): Reminds the community of their mission to guide the newly baptised into a life modeling Gospel values of compassion, humility, and service. Godparents and church leaders commit to supporting the individual's discipleship.
Affirmation of Faith (Linked to Proclamation of the Word): Serves as a public declaration of commitment to the Christian faith. Witnessing the baptism reinforces the community's own faith and spiritual commitment. In some Australian churches, holding baptisms during Mass (Catholic) creates a significant moment for both individual and congregation.
Sign of Hope and Unity (Linked to Baptismal Candle): Serves as a symbol of hope by reinforcing faith as a shared journey supported by the larger body of believers. The baptismal candle (lit from the Paschal candle) represents Christ as the light of the world, reminding the community to be a beacon of hope aligned with Matthew 5:16 ("Let your light shine before others, that they may see your good deeds and glorify your Father in heaven.").
