FIGURES OF SPEECH.
Also in this place (which we have been quoting),[1] the apostle to the Gentiles said that the wrath of God comes on the children of infidelity because of these evils.[2] When, however, he says, And you yourselves once walked in them when they were your life,[3] he shows well enough that they were not their life then. To them, indeed, they were dead, since their life was hidden with Christ in God. For the evils, in truth, were living in those who were not living in the evils, as I indicated a little while ago. Likewise, the vices, indeed, that were dwelling in the members of certain people were said to be their members, by a figure of speech in which the name of a place is given to the things contained within it, just as it is said that the whole forum speaks when what is meant is that the people who are in the forum are speaking. By this same figure of speech, there is sung in the psalm, Let all the earth adore you, that is, all people who are on the earth.
