Calvin on 1 Peter 4:3

But here a question arises, that Peter seems to have done wrong to many, in making all men guilty of lasciviousness, dissipation, lusts, drunkenness, and revellings; for it is certain that all were not involved in these vices; nay, we know that some among the Gentiles lived honourably and without a spot of infamy. To this I reply, that Peter does not so ascribe these vices to the Gentiles, as though he charged every individual with all these, but that we are by nature inclined to all these evils, and not only so, but that we are so much under the power of depravity, that these fruits which he mentions necessarily proceed from it as from an evil root. There is indeed no one who has not within him the seed of all vices, but all do not germinate and grow up in every individual. Yet the contagion is so spread and diffused through the whole human race, that the whole community appears infected with innumerable evils, and that no member is free or pure from the common corruption.
