Let the clear, convincing language of the Confession of Faith, touching the counterpart subject of justification, illustrate this statement. Chap. XI., Sec. 4: “God did, from all eternity, decree to justify all the elect; and Christ did, in the fullness of time, die for their sins, and rise again for their justification; nevertheless they are not justified until the Holy Spirit doth, in due time, actually apply Christ unto them.” By parity of reasoning, we hold that God did, from all eternity, decree to condemn all men descended from Adam by ordinary generation; and that Adam did, some time after his creation in holiness, sin and fall for them as well as for himself; nevertheless, individual fallen men are not condemned in him until such time as their existence doth actually unite them to Adam. And then it is a corrupted Adam to whom they are united.
How are “individual fallen men” united to Adam? Does it not happen at birth or in the womb but sometime after? I have never heard of this before.
At conception. Original sin/guilt discussions get so weird you have to remind yourself that people who don’t yet exist are not yet guilty.
