Isagoge in canonicas septem epistolas, qua (ut in Paulinis) compositionis oeconomia, et germana dispositio monstratur

now you have obtained it, beloved I urge you as strangers and pilgrims, etc. These things certainly cannot be understood only of the Jews. Thus in chapter 4, verse 3, he speaks with the faithful as if they were converted from the Gentiles.

OCCASION.

The occasion, as it appears, was offered by the arrival of Silvanus, who earlier had taught and established churches with Paul in diverse places, to which he was now about to return, and passing through Babylon, he met Peter there, as it seems, from whom he received this epistle to all the elect, so that they might partly be armed against open dangers, and partly instructed against false brothers, who here and there corrupted sound doctrine in various ways, just as Satan is a crafty interpreter of religion.
