By Carl E. Olson, Catholic World Report - In this Sunday’s Gospel, we find that the Jews—those religious leaders ardently opposed to the person and message of Jesus—were murmuring and complaining. They were upset by his claim to be the “bread of heaven that came down from heaven.” The basis for their murmuring disbelief can be summarized quite simply: “We know who this Jesus really is!” This exchange, after all, took place near Capernaum, which was the center for much of Jesus’ public life and ministry (cf. Jn. 2:12; Mk. 2:1)... Jesus responded to the complaints by appealing to the two authorities found throughout his discourses in the Fourth Gospel: the Father and the prophets.
