In a couple of the last posts there has been an ongoing discussion of the differences in the concept of Original Sin between Roman Catholicism and Orthodoxy. So, let me put a couple of citations from the Wikipedia that may help people to see the differences. Why from the Wikipedia? Well, because they are better at summarizing than theologians. 😯 I am aware that any summary always is insufficient, but sometimes we need summaries rather than details.
Augustine believed that the only definitive destinations of souls are heaven and hell. He concluded that unbaptized infants go to hell as a consequence of original sin. The Latin Church Fathers who followed Augustine adopted his position, which became a point of reference for Latin theologians in the Middle Ages. In the later mediaeval period, some theologians continued to hold Augustine’s view, others held that unbaptized infants suffered no pain at all: unaware of being deprived of the beatific vision, they enjoyed a state of natural, not supernatural happiness. Starting around 1300, unbaptized infants were often said to inhabit the “limbo of infants”. The Catechism of the Catholic Church, 1261 declares: “As regards children who have died without Baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them. Indeed, the great mercy of God who desires that all men should be saved, and Jesus’ tenderness toward children which caused him to say: ‘Let the children come to me, do not hinder them,’ allow us to hope that there is a way of salvation for children who have died without Baptism. All the more urgent is the Church’s call not to prevent little children coming to Christ through the gift of holy Baptism.” But the theory of Limbo, while it “never entered into the dogmatic definitions of the Magisterium … remains … a possible theological hypothesis”.
Augustine’s formulation of original sin was popular among Protestant reformers, such as Martin Luther and John Calvin . . .
In Eastern Orthodoxy, God created man perfect with free will and gave man a direction to follow. Man (Adam) and Woman (Eve) chose rather to disobey God by eating from the Tree of Knowledge of Good and Evil, thus changing the “perfect” mode of existence of man to the “flawed” mode of existence of man. This flawed nature and all that has come from it is a result of that “original sin”. All humanity shares in the sin of Adam because like him, they are human. The union of humanity with divinity in Jesus Christ restored, in the Person of Christ, the mode of existence of humanity, so that those who are incorporated in him may participate in this mode of existence, be saved from sin and death, and be united to God in deification. Original sin is cleansed in humans through baptism or, in the case of the Theotokos, the moment Christ took form within her.
This view differs from the Roman Catholic (Augustinian) doctrine of Original Sin in that man is not seen as inherently guilty of the sin of Adam. According to the Orthodox, humanity inherited the consequences of that sin, not the guilt. The difference stems from Augustine’s interpretation of a Latin translation of Romans 5:12 to mean that through Adam all men sinned, whereas the Orthodox reading in Greek interpret it as meaning that all of humanity sins as part of the inheritance of flawed nature from Adam. The Orthodox Church does not teach that all are born deserving to go to hell, and Protestant doctrines such as Predeterminism that derive from the Augustinian understanding of original sin are not a part of Orthodox belief.
