St. Peter Casting Himself into the Water to Meet Jesus – Tissot

This is when Jesus manifested Himself for the third time to His disciples after He rose from the dead. The art image by J. Tissot shows the Apostle (and first Pope) Simon Peter jumping into the Sea of Tiberius to meet with Christ. 

"That disciple therefore whom Jesus loved, said to Peter: It is the Lord. Simon Peter, when he heard that it was the Lord, girt his coat about him, (for he was naked,) and cast himself into the sea." — John 21:7
