1. **Human Nature:** Augustine believed that human beings were originally created in a state of perfection and goodness. He affirmed the idea that humans are made in the image of God and possess rationality, freedom of the will, and the ability to love. Augustine emphasized the harmony between the soul and the body, asserting that both were created good and meant to work together.
2. **Original Sin:** Augustine taught that through the disobedience of Adam and Eve in the Garden of Eden, sin entered the world and profoundly affected human nature. He viewed original sin as a hereditary condition that is passed down from generation to generation. According to Augustine, all human beings inherit a sinful nature from Adam, and this nature inclines them towards selfishness, pride, and rebellion against God.
3. **Total Depravity:** Augustine argued for the concept of "total depravity," which does not mean that every human being is as evil as they could possibly be but rather that sin has affected every aspect of human nature. He believed that the Fall corrupted the will, intellect, and desires of human beings, rendering them unable to choose or desire the good without the assistance of God's grace.
4. **Need for Divine Grace:** Augustine emphasized the absolute necessity of God's grace for human salvation. He taught that humans, due to their fallen nature, cannot save themselves or earn salvation through their own efforts. Instead, they are wholly dependent on God's grace and mercy to be redeemed and reconciled to Him. Augustine argued that God's grace is necessary to restore and transform human nature, enabling individuals to respond in faith and receive salvation.
