Q16. Did all mankind fall in Adam's first transgression?

The covenant being made with Adam, not only for himself, but for his posterity; all mankind, descending from him by ordinary generation, sinned in him, and fell with him, in his first transgression.

Scripture Proofs — King James Version

1

Romans 5:12

Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.

1 Corinthians 15:21–22

For since by man came death, by man came also the resurrection of the dead. For as in Adam all die, even so in Christ shall all be made alive.

CommentaryThomas Vincent (1674)

Question 1. Did all mankind without any exception, fall in Adam's first transgression?

Answer. No: For our Lord Jesus Christ, who was one of Adam's posterity, did not fall with Adam, but was perfectly free both from original and actual sin, Heb. 7:26. "Such an high priest became us, who was holy, harmless, undefiled, separate from sinners", 1 Pet. 2:22. "Who did no sin".

Question 2. How was it that the Lord Jesus Christ escaped the fall with Adam?
