Second Sunday After Easter

This Sunday is often called Good Shepherd Sunday: the Gospel tells us of the Good Shepherd. Jesus is indeed the Good Shepherd of our souls. He came to give His life for us.
The Roman Missal, 1962

At that time Jesus said to the Pharisees: I am the good Shepherd. The good Shepherd giveth His life for His sheep. But the hireling, and he that is not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth and scattereth the sheep: and the hireling fleeth, because he is a hireling and he hath no care for the sheep. I am the good Shepherd: and I know Mine, and Mine know Me. As the Father knoweth Me, and I know the Father: and I lay down My life for My sheep. And other sheep I have that are not of this fold: them also I must bring, and they shall hear My voice, and there shall be one fold and one shepherd. (St. John 10. 11-16)
