1Pet 5:9

“Resist strong in faith, etc. Be (he says) so much stronger in faith, have so much more patience to overcome the deceits of the devil, as it is certain that you are not tempted alone, but the same passion that wearies you is common to the Church of Christ which is throughout the whole world, that is to say, to your brotherhood. And because the righteous have always suffered since the foundation of the world, let it shame you to be unable to endure alone above all others.”

“The soul is disposed to the gift of fortitude through the unconquerable shield of faith. The devil draws man to the concupiscence of the flesh, to the concupiscence of the eyes, and to the pride of life. What is the means of resisting these? Through truth. "His truth shall encompass you with a shield," namely through faith dwelling within. And blessed Peter said: "Your adversary as a roaring lion goes about seeking whom he may devour: whom resist, strong in faith." If we loved truth, we would not fear the devil, because it is written: "The eyes of the Lord behold the whole earth and give fortitude to those who believe in him with a perfect heart."”

“"knowing that the same kinds of suffering," as it is likely, those to whom Peter writes were being pressed by many afflictions for the sake of Christ: therefore, both in the preceding and in the following, he brings consolation to this: indeed, by the fact that the enduring become themselves partakers of the afflictions of Christ and heirs of the glory that is to be revealed; here, however, by the fact that they do not suffer alone, but all the faithful who are in the world: moreover, the company of companions lightens the severity.”
