John Calvin Commentary 1 Corinthians 13:10

"but when that which is perfect is come, that which is in part shall be done away." — 1 Corinthians 13:10 (ASV)

When that which is perfect is come. “When the goal has been reached, then the helps in the race will be done away.” He retains, however, the form of expression that he had already used, when he contrasts perfection with what is in part. “Perfection,” he says, “when it arrives, will put an end to everything that aids imperfection.”

But when will that perfection come? It begins, indeed, at death, for then we put off, along with the body, many weaknesses; but it will not be completely manifested until the day of judgment, as we shall hear shortly. Therefore, we infer that the whole of this discussion is ignorantly applied to the intermediate time.
