John Calvin Commentary John 20:25

"The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in his hands the print of the nails, and put my hand into his side, I will not believe." — John 20:25 (ASV)

Unless I see in his hands the print of the nails. This points out that the source of this vice is that everyone wishes to be wise from their own understanding and flatters himself beyond measure. If I do not see, he says, “and if I do not touch, I will not believe.” These words have no approach to faith, but it is what may be called a sensual judgment, by which I mean, a judgment which is founded on the perception of the senses. The same thing happens to all who are so devoted to themselves that they leave no room for the word of God.

It is of no consequence whether you read the place, or the shape, or The Print of the nails; for transcribers may have exchanged τύπον (print) for τόπον (place), or τόπον (place) for τύπον (print); but the meaning is not altered on that account. Let the reader, therefore, choose whichever of them he prefers.
