I don't think we are born condemned for Adam's sin, rather, I think we come under condemnation when we knowingly (and inevitably) choose to sin. David speaks of the "sinful nature" that Adam's original sin passed to his mother, of whom he was born. The Catholic church has always taught that babies are born condemned by Adam's sin and need to be baptized to "wash away original sin", lest they die condemned. In the past, regional bans of religious rites, such as infant baptism, over an entire area were effective in frightening the people into pressuring the out of line secular authority to resubmit to the supreme authority of the church, at which time it was lifted. Protestants interpreted the Bible as teaching that Jesus removed the guilt of original sin from us the instant that it passed to us when he stepped in between it and Adam and Eve in promising to take the guilt upon Himself at Calvary.
Interesting. Do you think that 1 Corinthians 7:14 talks about children being born forgiven because of the faith of one of their parents? Of course that if this were the case those children would still need repentance and conversion in the future, once their reason is strong enough to understand these concepts. However, they would be saved (in every sense of the word) during their infancy because of the faith of one (or both) of their parents. Is this what you believe?
