Again we see that mysterious image of John the Baptist, the burning and shining light who bore witness by his life and death to Jesus Christ. “He must increase, and I must decrease,” said this prophet, this man whose unique vocation was that he bridged the Old Testament and the New. Two weeks ago we saw that all of the scriptures bore witness to Jesus Christ; and now, this last prophet of the Old Covenant bears direct witness to Christ, baptizing Him, and seeing the Spirit of God come upon Him as a dove out of Heaven. This last prophet of the Old Covenant is the first prophet of the New Covenant. The Lord said through the prophet Isaiah, “Behold, I will do a new thing; now it shall spring forth; shall ye not know it? I will even make a way in the wilderness, and rivers in the desert (Isa. 43: 19).” God called this prophet, this unique prophet, to show that the new thing, the New Covenant spoken of by Jeremiah the prophet (Jer. 31:31f) was upon them. John’s father was a priest under the Law of Moses, a descendent of Aaron. Therefore, John was also, by that Law, a priest. Yet, John the son of Zechariah, went into the desert to be the voice of one crying in the wilderness, “prepare the way of the Lord.”
This Suffering servant, after His death in their place, rises and takes up a ministry of intercession for sinners. “When thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand.” A dead man cannot prolong his days unless he rises again. In this passage, His death and resurrection are priestly, because he dies as the one true sacrifice, the atonement, and after rising “he ever lives to make intercession for them,” that is, for those who come to God through Him (Hebrews 7:25). The Old Testament sacrifices on those altars foreshadowed His true sacrifice, just as our sacrifice on this altar, in which nothing is killed, proclaims it. In fact, there is only one Mass (Eucharist or Holy Communion), and always when it is offered anywhere in the world by the Church, it is joined to the one true sacrifice on Calvary.
When he comes again, the image of Messiah as King will be fulfilled in all of its glory. This is the terror of all that is evil, and it is the hope of the Church. It is a certainty that he will come on the Last Day to judge the living and the dead, to establish Heaven on Earth, to rule and so grant peace forever. Both testaments speak of His coming as the King Messiah. Daniel saw one coming in the clouds of Heaven as the Son of man to rule with the Ancient of Days; Moses saw that “the Earth shall be filled with the glory of the Lord as the waters cover the sea.” Our eternal hope is not based upon imagination and conjecture, but upon the sure promise given in and by Christ’s resurrection from the dead. We are given the “sure and certain hope of the resurrection on the Last Day.” It is the only such hope, and it is impossible to separate that hope from Jesus Christ, because immortality, the hope of eternal life, is granted through His resurrection. So writes Saint John about those who, due to this hope, purify themselves: “Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is (I John 3:2).”
John the Baptist prepared the way of the Lord by his message of repentance. Pondering these pictures of the Messiah as priest and King we are both warned and encouraged with both fear and hope. This is the meaning of Advent. It is of eternal consequence that we give heed.
