In the East: The primary consequence of Original Sin is death. The reality of death causes people to desire that which can distract them from the reality of their impending death. Hence, people turn to sex, money, and power as a way to forget about death. In this way, death leads to sin.
In the West: The primary consequence of Original Sin is a “stain” of guilt. People are born with a guilt that needs to be washed away as soon as possible.
Both the East and the West agree that original sin causes an ABSENCE of the indwelling of the Holy Spirit. Through baptism, the Holy Spirit can again dwell within man.
The differences between East and West are not great; it is more of an emphasis on different aspects, rather than differences in theology.
That is correct, Mark. Sin is death because it is separation from God, Who is Life. And salvation means to be saved from death.
