Cosmas Indicopleustes : For if the dead rise not, neither hath Christ risen, but if Christ hath not risen, your faith is vain—-ye are yet in your sins; from that which was confessed and believed in by them, he confutes them and says: for if He, concerning whom you have believed, when He was dead rose again, why do you doubt the resurrection of the other dead, so that you make it appear that you have believed in vain about the resurrection of but one. For he, who is able to raise one of the dead, is able also to raise all the others that are dead. So that by not believing in the resurrection of the dead, you revert to your former superstition, and have fallen away, for this he means by saying: Ye are yet in your sins. — The Christian Topography, Book 7 John Chrysostom : And again he establishes it all, and takes it up again, saying, "For if the dead are not raised, neither hath Christ been raised." For had He not intended to do this, He would not have come into the world. And he names not this, but the end, to wit, His resurrection; through it drawing all things. — Homily on 1 Corinthians 39 Pelagius : In other words, if you accept that Christ rose from the dead, believe that we shall rise again also. — COMMENTARY ON THE FIRST EPISTLE TO THE CORINTHIANS 15
