8. But as the wills of friends, which are not seen, are believed through tokens which are seen; thus the Church, which is now seen, is, of all things which are not seen, but which are shown forth in those writings wherein itself also is foretold, an index of the past, and a herald of the future. Because both things past, which cannot now be seen, and things present which cannot be seen all of them, at the time at which they were foretold, no one of these could then be seen. Therefore, since they have begun to come to pass as they were foretold, from those things which have come to pass unto those which are coming to pass, those things which were foretold concerning Christ and the Church have run on in an ordered series: unto which series these pertain concerning the day of Judgment, concerning the resurrection of the dead, concerning the eternal damnation of the ungodly with the devil, and concerning the eternal recompense of the godly with Christ, things which, foretold in like manner, are yet to come. Why therefore should we not believe the first and the last things which we see not, when we have, as witnesses of both, the things between, which we see, and in the books of the Prophets either hear or read both the first things, and the things between, and the last things, foretold before they came to pass? Unless haply unbelieving men judge those things to have been written by Christians, in order that those things which they already believed might have greater weight of authority, if they should be thought to have been promised before they came.
