Bede the Venerable
Catena Aurea · Johannesevangelium 6
For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him. As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever. These things said he in the synagogue, as he taught in Capernaum.
Mystically, Capernaum, which means beautiful town, stands for the world: the synagogue, for the Jewish people. The meaning is, that our Lord hath, by the mystery of the incarnation, manifested Himself to the world, and also taught the Jewish people His doctrines.
