Though this is a new precept, it yet depends on what is gone before, for he requires such constancy in the faithful, as boldly to give a reason for their faith to their adversaries. And this is a part of that sanctification which he had just mentioned; for we then really honor God, when neither fear nor shame hinders us from making a profession of our faith. But Peter does not expressly bid us to assert and proclaim what has been given us by the Lord everywhere, and always and among all indiscriminately, for the Lord gives his people the spirit of discretion, so that they may know when and how far and to whom it is expedient to speak. He bids them only to be ready to give an answer, lest by their sloth and the cowardly fear of the flesh they should expose the doctrine of Christ, by being silent, to the derision of the ungodly. The meaning then is, that we ought to be prompt in avowing our faith, so as to set it forth whenever necessary, lest the unbelieving through our silence should condemn the religion we follow.

But it ought to be noticed, that Peter here does not command us to be prepared to solve any question that may be mooted; for it is not the duty of all to speak on every subject. But it is the general doctrine that is meant, which belongs to the ignorant and the simple. Then Peter had in view no other thing, than that Christians should make it evident to unbelievers that they truly worshipped God, and had a holy and good religion. And in this there is no difficulty, for it would be strange if we could bring nothing to defend our faith when any one made inquiries respecting it. For we ought always to take care that all may know that we fear God, and that we piously and reverently regard his legitimate worship.

This was also required by the state of the times: the Christian name was much hated and deemed infamous; many thought the sect wicked and guilty of many sacrileges. It would have been, therefore, the highest perfidy against God, if, when asked, they had neglected to give a testimony in favor of their religion. And this, as I think, is the meaning of the word apology, which Peter uses, that is, that the Christians were to make it evident to the world that they were far off from every impiety, and did not corrupt true religion, on which account they were suspected by the ignorant.

Hope here is by a metonymy to be taken for faith. Peter, however, as it has been said, does not require them to know how to discuss distinctly and refinedly every article of the faith, but only to shew that their faith in Christ was consistent with genuine piety. And hence we learn how all those abuse the name of Christians, who understand nothing certain respecting their faith, and have nothing to give as an answer for it. But it behoves us again carefully to consider what he says, when he speaks of that hope that is in you; for he intimates that the confession which flows from the heart is alone that which is approved by God; for except faith dwells within, the tongue prattles in vain. It ought then to have its roots within us, so that it may afterwards bring forth the fruit of confession.
