I am the Good Shepherd. Surely it is fitting that Christ should be a shepherd, for just as a flock is guided and fed by a shepherd so the faithful are fed by Christ with spiritual food and with his own body and blood. The Apostle said: You were once like sheep without a shepherd, but now you have returned to the guardian and ruler of your souls. The prophet has said: As a shepherd he pastures his flock.

Christ said that the shepherd enters through the gate and that he is himself the gate as well as the shepherd. Then it is necessary that he enter through himself. By so doing, he reveals himself, and through himself he knows the Father. But we enter through him because through him we find happiness.
