He Who was baptized in the Jordan
The Baptism in the Jordan
Matthew 28:19
Going therefore, teach ye all nations; baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.Christ had already followed this example, as we find at the start of his public life in Matthew 3:13-17
Then cometh Jesus from Galilee to the Jordan, unto John, to be baptized by him. But John stayed him, saying: I ought to be baptized by thee, and comest thou to me? And Jesus answering, said to him: Suffer it to be so now. For so it becometh us to fulfill all justice. Then he suffered him. And Jesus bing baptized, forthwith came out of the water: and lo, the heavens were opened to him: and he saw the Spirit of God descending as a dove, and coming upon him. And behold a voice from heaven, saying: This is my beloved Son, in whom I am well pleased.
I am reminded of an incident with St. Faustina, to whom was revealed the Divine Mercy. Our Lord told her to ask her superior to allow her to adore at midnight. She did, and was told no. He repeated this request several times, and each time she asked her superior, who denied her request. Finally, St. Faustina's superior told her not to ask her anymore.
The next time Our Lord asked her to adore Him at midnight, she replied in distress that her superior had again said no, and had ordered her not to ask again. Jesus replied that he had done this to make clear to her that he exercises his authority through his church, and that she must be obedient to her superior.
By himself being baptized "to fulfill all justice," Christ shows us the important of this as a sacrament. Though sinless, he accepted cleansing from sin, just as he would later accept their punishment.
Christ was baptized so that we could be baptized with him, anointed with him.
