John 6:59

"These things said He in the synagogue, as He taught in Capernaum." The place where most of His marvels had been done, so that He ought there especially to have been listened to. But wherefore taught He in the synagogue and in the Temple? As well because He desired to catch the greatest number of them, as because He desired to show that He was not opposed to the Father.

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.

(Hom. xlvii. 1) For if it was possible without harvest or fruit of the earth, or any such thing, to preserve the lives of the Israelites of old for forty years, much more will He be able to do this with that spiritual food, of which the manna is the type. He knew how precious a thing life was in men's eyes, and therefore repeats His promise of life often; just as the Old Testament had done; (Exod. 20:12) only that it only offered length of life, He life without end. (Deut. 22:7) This promise was an abolition of that sentence of death, which sin had brought upon us. These things said He in the synagogue, as He taught in Capernaum; (1 Kings 3:14) where many displays of His power took place. (Ps. 21:4; 91:16) He taught in the synagogue and in the temple, (Prov. 3:2) with the view of attracting the multitude, and as a sign that He was not acting in opposition to the Father.
