Gregory the Great

To Peter was the holy Church committed; to him is it specially said, Feed My sheep. That then which is afterwards declared by word, is now signified by act. He it is who draws the fishes to the firm shore, because he it was who pointed out the stability of the eternal country to the faithful. This he did by word of mouth, by epistles; this he does daily by signs and miracles. After saying that the net was full of great fishes, the number follows: Full of great fishes, an hundred and fifty and three.
