John 6:1

Galilee. St. John does not usually relate what is mentioned by the other evangelists, especially what happened in Galilee. If he does it on this occasion, it is purposely to introduce the subject of the heavenly bread, which begins ver. 37. He seems, moreover, to have had in view the description of the different passovers during Christ's public ministry. As he, therefore, remained in Galilee during the third passover, he relates pretty fully what passed during that time. We must also remark, that as the other three evangelists give, in the same terms, the institution of the blessed sacrament, St. John omits the institution, but gives in detail the repeated promises of Jesus Christ, relative to this great mystery.
