1 Corinthians 15:1

Moreover, (1) brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye (a) stand;

(1) The sixth treatise of this epistle, concerning the resurrection: and he uses a transition, or passing over from one matter to another, showing first that he brings no new thing, to the end that the Corinthians might understand that they had begun to swerve from the right course. And next that he does not go about to entreat of a trifling matter, but of another chief point of the Gospel, which if it is taken away, their faith will necessarily come to nothing. And so at the length he begins this treatise at Christ's resurrection, which is the ground and foundation of ours, and confirms it first by the testimony of the scriptures and by the witness of the apostles, and of more than five hundred brethren, and last of all by his own.

(a) In the profession of which you still continue.
