John Calvin Commentary 1 Timothy 2:14

"and Adam was not beguiled, but the woman being beguiled hath fallen into transgression:" — 1 Timothy 2:14 (ASV)

And Adam was not deceived. He alludes to the punishment inflicted on the woman:

Because thou hast obeyed the voice of the serpent, thou shalt be subject to the authority of thy husband, and thy desire shall be to him (Genesis 3:16).

Because she had given fatal advice, it was right that she should learn that she was under the power and will of another; and because she had drawn her husband aside from the command of God, it was right that she should be deprived of all liberty and placed under the yoke. Besides, the Apostle does not rest his argument entirely or absolutely on the cause of the transgression, but founds it on the sentence that was pronounced by God.

Yet it may be thought that these two statements are somewhat contradictory: that the woman's subjection is the punishment for her transgression, and yet that it was imposed on her from the creation. For from this it will follow that she was doomed to servitude before she sinned. I reply, nothing hinders the condition of obeying from being natural from the beginning, and the accidental condition of serving from coming into existence afterwards; so that the subjection was now less voluntary and agreeable than it had formerly been.

Again, this passage has given some people an occasion to affirm that Adam did not fall through error, but was only overcome by his wife's allurements. Accordingly, they think that only the woman was deceived by the devil's wiles into believing that she and her husband would be like the gods; but that Adam was not at all persuaded of this, but tasted the fruit to please his wife. However, it is easy to refute this opinion, for if Adam had not believed Satan's falsehood, God would not have reproached him:

Behold, Adam is become like one of us (Genesis 3:22).

There are other reasons of which I say nothing, for a long refutation of an error that does not rest on any probable conjecture is not needed. By these words Paul does not mean that Adam was not entangled by the same deceitfulness of the devil, but that the cause or source of the transgression proceeded from Eve.
