Comprehensive Study Notes: Christianity—Life, Teachings of Jesus & Historical Development

Historical Prelude, Prophetic Background, and the Advent of John the Baptist

  • Core proclamation: “Repent, for the Kingdom of God is at hand.”
    • Rooted in messianic prophecies of the Hebrew Bible (OT) – expectation of an “anointed one” who ends oppression and inaugurates a new Exodus‐like redemption.
  • John the Baptist’s role
    • Baptizes in Judea, warns that sin delays the Messiah’s arrival.
    • Functions as final OT‐style prophet bridging Law/Prophets → Gospel.

The Inauguration of Jesus’ Public Ministry

  • Baptism in the Jordan
    • Theophany: Spirit descends “as a dove,” voice declares, “This is my beloved Son….”
  • Forty-day wilderness fast → triple “Temptation” by Satan (symbolic 40 = Israel’s desert years).
  • Synagogue reading (Isaiah 61)
    • Announces mandate: preach good news, free captives, heal blind, proclaim “Year of the Lord’s Favor.”
    • Declaration: “Today this scripture is fulfilled in your hearing.”
  • Call of the Twelve
    • Creates new Israel (12 tribes) → apostolic foundation; names not supplied in transcript but implied.
  • Three-year itinerant campaign
    • Healings (including congenital illness), exorcisms, nature miracles – interpreted as “signs” validating arrival of the Kingdom of God (KoG).

Jesus’ Doctrine of the Kingdom of God (KoG)

  • Temporal tension
    • “Already / not yet” – KoG is present (“in your midst”) yet awaiting future consummation at the Last Day.
  • Historical shift
    • Age of Law & Prophets → Age of Gospel / New Covenant (fulfillment, not abolition).
  • Ethical revolution (Sermon on the Mount et al.)
    • Love enemies, bless persecutors, radical forgiveness.
    • Interior purity > external ritual; divine ethos embodied.
    • Paradoxical greatness: “Whoever wants to be first must be last, servant of all.”
    • Humility of a child prerequisite for entry; contrasts rabbinic ritual precision.
  • Cost of discipleship
    • Possible rupture with family, forfeiture of wealth, martyrdom (“If you’re not for me, you’re against me”).

Parables & the Messianic Secret

  • Teaching method: agrarian metaphors – mustard seed, sower, hidden treasure; concludes, “He who has ears, let him hear.”
  • Repeated hush‐orders after confessions (“You are the Son of God…don’t tell anyone”).
    • Prevents misinterpretation of Messiah as militant revolutionary; distinguishes spiritual‐ethical kingdom from political revolt (“Render unto Caesar…”).
  • Judas Iscariot—likely Zealot ideology—betrays for 30 silver when Jesus rejects armed uprising.

Conflict with Religious & Social Establishment

  • Boundary‐breaking associations: tax collectors, prostitutes, Samaritans, women, Gentiles.
  • Sabbath controversies: grain plucking, healing.
  • Antitheses formula: “You have heard… but I say….”
  • Claims of divine prerogatives
    • Forgiving sin; pre-existence: “Before Abraham was, I am.”
    • Unity with God: “I and the Father are one.”

Passion Week – From Triumphal Entry to Golgotha

  • Palm Sunday: rides donkey; crowd acclaims Messiah.
  • Temple cleansing: indicts corruption → escalates threat level.
  • Authorities seek private arrest → collude with Judas; timing = Passover Seder (Last Supper).
  • Jewish trial
    • Sanhedrin interrogates: “Are you the Messiah?” Jesus affirms, quotes Daniel 7.
    • Charge: blasphemy → death, but Roman authorization needed.
  • Roman trial
    • Pilate indicts for treason (“King of the Jews”) → sentence: crucifixion.
  • Good Friday details
    • Flogging, cross-bearing, execution by asphyxiation.
    • Usual denial of burial averted by Joseph of Arimathea; body entombed pre-Sabbath.
    • Lance pierces side: blood & water = death verification.

Christological Titles & OT Allusions

  • “Son of Man” – Daniel 7 vision: everlasting dominion.
  • “Suffering Servant” – Isaiah 53: vicarious suffering.
  • “Messiah / Son of God / Lord”
    • Davidic kingship eternal; dual Jewish & Greco-Roman connotations of divine sonship.
    • First advent = humble servant; second advent = glorious judge.

Resurrection, Ascension, and Eschatological Promise

  • Easter Sunday: women find empty tomb; angelic announcement.
  • Post-resurrection appearances – physical, tangible, eats; 500 witnesses over 40 days.
  • Great Commission + promise of Holy Spirit.
  • Ascension: visible departure; angels predict identical return.

Pentecost – Birth of the Church

  • Festival Shavuoth (≈ 50 days post-Passover).
  • Holy Spirit descent – tongues (glossolalia); public preaching in multiple languages.
  • Thousands convert; healing ministry continues → nascent Church.

Early Persecutions & Pauline Mission

  • Rabbinic opposition: Council under Gamaliel debates; Saul of Tarsus authorized to suppress.
  • Damascus‐road theophany blinds Saul → conversion to “Paul,” primary Gentile missionary.
  • Debate on Mosaic Law for Gentiles
    • James (Jerusalem) = full Torah observance; Paul = freedom from Law, life under grace; Peter vision re: pork tips scale.
  • Paul’s three missionary journeys – church planting; epistles for doctrinal guidance.

From Jewish to Roman Persecution & Imperial Turnaround

  • Paul appeals to Caesar, under house arrest in Rome.
  • Nero (64 CE) scapegoats Christians after Great Fire; accusation: “hating the human race.”
  • Cycles of martyrdom until Constantine’s Edict of Milan (313\,\text{CE}) legalizes Christianity; Theodosius I makes it state religion (380\,\text{CE}).
  • Secret symbols (e.g., Ichthys fish) used during repression.
  • Constantine
    • Convenes Council of Nicea (325—typo in transcript 425); funds Church, institutes Sunday sabbath & Christmas; founds Constantinople (capital until 1453 Ottoman conquest).

Apostolic Succession & Ecclesial Structure

  • Rationale: safeguarding unity & orthodoxy.
  • Hierarchy crystallizes:
    • Priest → Bishop (diocese) → Archbishop (province) → Patriarch (five sees: Rome, Alexandria, Jerusalem, Antioch, Constantinople).
    • Roman primacy grounded in Matthew 16:13–19 (“Thou art Peter…”).
  • Episcopate succession traced to the Twelve; leader in Rome eventually titled Pope.

Doctrinal Developments: Salvation & Atonement

  • Human predicament – “Fall of Man”
    • Sin → alienation → mortality.
  • Soteriology
    • Grace-based forgiveness → reconciliation → adoption; believers become “partakers of the divine nature.”
  • Atonement (“Great Exchange”) – substitutionary
    • “God made him who had no sin to be sin for us…”
    • Cross defeats sin, Satan, death; resurrection liberates captives.
    • Typology: Passover lamb, Yom Kippur sacrificial system fulfilled.
  • Incarnation purpose
    • God experiences full human condition; heals it from within; climactic victory converts greatest evil into greatest good.

Christological & Trinitarian Councils (325-451)

  • Nicea 325 – combats Arianism; Jesus consubstantial (same essence) with Father.
  • Constantinople 381 – clarifies Spirit’s divinity.
  • Ephesus 431 – affirms Mary “Theotokos,” counters Nestorian separation.
  • Chalcedon 451 orthodox formula: one person, two natures “without confusion, conversion, division, or separation.”
  • Rejected heresies
    • Docetism (illusionary humanity), Arianism (created Son), Nestorianism (dual persons), Eutychianism (hybrid nature).

The Three Great Christian Traditions

Roman Catholicism

  • Distinctives
    • Papal supremacy & infallibility (dogmatized Vatican I 1869–70).
    • Sacramental mediation – 7 sacraments; “extra ecclesiam nulla salus.”
    • Developing Mariology (Mother of God, Immaculate Conception 1854, Assumption 1950).
  • Sacraments timeline
    • Baptism → Confirmation → Eucharist (transubstantiation decreed 1215) → Penance/Confession (+ indulgences 11^{th} c.; dogma 1343) → Anointing of Sick → Marriage → Holy Orders.
  • Augustine’s influence: sacraments as “visible signs of invisible grace,” original sin, necessity of infant baptism.

Eastern Orthodoxy

  • Authority vested in first 7 Ecumenical Councils; rejects papal jurisdiction.
  • Great Schism 1054 (mutual excommunications; filioque dispute).
  • Theological emphases
    • Icons as windows to divine, 2-D stylization, veneration not worship.
    • Theosis/deification: “God became man that man might become God.”
    • Via negativa – apophatic theology.
  • Accepts earlier Marian titles but denies Immaculate Conception & Assumption; rejects Augustine’s original-sin theory; married priests permitted if married pre-ordination.

Protestantism (Reformation Onward)

Foundational Principles (Luther, 1517)

  1. Sola Scriptura – Bible alone infallible.
  2. Sola Fide – justification by faith alone.
  3. Priesthood of all believers – no mediatorial caste; rejects sacramental necessity, purgatory.
  • Luther translates Bible to German; condemned for heresy yet movement spreads.

Reformed Tradition (Zwingli, Calvin)

  • More radical purge of Catholic elements: iconoclasm, state-church synergy.
  • Calvin’s Institutes – original sin + double predestination; influences Presbyterianism and Puritan social vision (Weber’s thesis on capitalism).

Radical Reformation (Anabaptists/Mennonites)

  • Voluntary believers’ church, pacifism, strict church-state separation; reject infant baptism, Augustinian sin, Calvinist predestination.

Anglicanism (Church of England)

  • Political origin: Henry VIII’s Act of Supremacy 1534; via media liturgy; 39 Articles (Elizabeth I).
  • Puritan dissent → migration to America; KJV Bible 1611.

Methodism & Revivalism (John Wesley)

  • “Holy Club,” disciplined piety → Great Awakenings; experiential “born again” ethos; global evangelicalism.

Modern Theological Currents

  • Enlightenment rationalism (Deism, atheism). Darwin 1859 fuels naturalistic worldview.
  • Liberal Theology / Higher Criticism
    1. Harmonize faith with reason/science; Bible as human literature.
    2. Universal salvation, ethical humanism, social gospel; skepticism of afterlife.
    3. Jesus as moral exemplar; rejects miracles, virgin birth, divinity.
  • Fundamentalism (late 19^{th}–early 20^{th})
    1. Biblical inerrancy.
    2. Full deity/humanity of Christ, virgin birth.
    3. Substitutionary atonement; bodily resurrection.
    4. Future judgment, resurrection, Second Coming.
  • Denominational mergers: e.g., United Church of Canada 1925 (liberal Methodist, Presbyterian, Congregational).

Chronological Milestones & Key Numbers (select)

  • 33\,\text{AD} – traditional date of crucifixion/resurrection.
  • 40 – days of wilderness temptation & post-resurrection appearances.
  • 50 – days between Passover & Pentecost (Greek “pentekoste”).
  • 71 – members of the Sanhedrin.
  • 313 – Edict of Milan legalizes Christianity.
  • 451 – Council of Chalcedon defines two-nature Christology.
  • 1054 – Great Schism.
  • 1517 – Luther’s 95 Theses.
  • 1648 – Peace of Westphalia ends European religious wars.
  • 1869–70 – Vatican I affirms papal infallibility.

Ethical, Philosophical, and Practical Implications

  • Christianity consistently frames liberation (Exodus typology) as both spiritual (sin/death) and socio-ethical (oppression/injustice).
  • Concept of servant leadership influences modern ethics, nonviolent activism.
  • Doctrines of human fallenness vs. perfectibility inform contemporary debates on education, governance, psychology.
  • Trinitarian relationality undergirds Christian social thinking on community, love, and personhood.
