Romans 5:12
12Therefore, as sin entered into the world through one man, and death through sin, so death passed to all men because all sinned.
Therefore, as sin entered into the world through one man, and death through sin, so death passed to all men because all sinned. Wesley will name the figure in v. 14: Adam is a public person, a federal head of mankind, the fountain of sin and death to mankind by his offence. All sinned: not a private copycat, but the race in its head.
Classical Arminians keep federal headship here. Death spread to all because all sinned in the one man—Wesley: being then in the loins of their first parent, the common head and representative of them all. Both camps must say this together first. The fork is not whether Adam is head; it is how far the second Adam’s gift runs (vv. 15–19).
Sin came through one man, death through sin, death to all because all sinned. Calvin: frivolous was the Pelagian gloss that sin descended by imitation from Adam to the whole human race; for Christ would in this case become only the exemplar and not the cause of righteousness. He speaks not here of actual sin: if everyone for himself contracted guilt, why compare Adam and Christ? Innate and hereditary depravity is what is referred to.
Adam is federal head, not a bad example we happen to copy. The comparison with Christ requires a headship on both sides. All sinned in the one man; the whole mass is involved. Do not flatten this into each person’s isolated fall. The second Adam will be cause of righteousness, not a mere pattern.
