Only God could make the Christian Religion. To take millions of men who hate and fear and kill each other, to bring them to accept one Faith and to live under one law of love – this is to prove that Christ was God. His Church is Divine on its own merits. But there are other and greater reasons: the miracles and the prophecies of the Founder. No created agent can of himself perform miracles. They transcend the powers of nature and require the special intervention of God. For this reason, the Evangelist, St. John, having related some of the many miracles of Christ – culminating in the most glorious of them all, His Resurrection from the dead – concludes the twentieth chapter of his Gospel with this striking passage: “Many other signs also did Jesus in the sight of his disciples, which are not written in this book; but these are written, that you may believe that Jesus is the Christ, the Son of God: and that believing, you may have life in his name” (John 20:30). The Gospel of St. John was written to prove that Jesus is God.
Prophecies are possible only to God. To predict future free events without supernatural aid is outside the pale of a created intelligence. Prophecies are in themselves miracles. For this reason, Jesus made use of prophecies to assert His divinity. The most terrible of all His prophecies was fulfilled only thirty-seven years after the Crucifixion (i.e., the destruction of Jerusalem by the Romans under Titus in 70 A.D.) – and Jesus concludes it with these words: “Amen, I say to you, that this generation shall not pass, till all these things be done” (Matt. 24:34). For the awful truth that lay hidden in these words, read the history of Josephus on the fall of Jerusalem.
By His universal knowledge of creation, especially in the searching of hearts, Jesus showed that He was God. “Nathaniel saith to him: ‘Whence knowest thou me?’ Jesus answered and said to him: ‘Before that Philip called thee, when thou wast under the fig tree, I saw thee’.” (John 1:48). “And because he needed not that any should give testimony of man: for he knew what was in man” (John 2:25).
Innumerable texts in the Scriptures bear testimony to the divinity of the Child Jesus. His coming will be preceded by a universal peace. (Cf.Ps. 71). “His name shall be called Wonderful, Counsellor, God the Mighty, the Father of the world to come, the Prince of Peace” (Is. 9:6). At His birth “there was with the Angel a multitude of the heavenly army, praising God and saying: ‘Glory to God in the highest, and on earth peace to men of good will’.” (Luke 2:47).
Even the enemies of Christianity are compelled to admit that “the morality of Jesus Christ is the foundation of human civilization” (Strauss). Another unbeliever declares that “the moral teaching of Jesus is the most beautiful doctrine ever received: the Sermon on the Mount will never be surpassed” (Renan).
Christ’s Passion and Death are worthy only of God made man. “For, let this mind be in you, which was also in Christ Jesus, Who, being in the form of God, thought it not robbery to be equal with God: but emptied Himself, taking the form of a servant, being made in the likeness of men, and in habit found as a man. He humbled Himself, becoming obedient unto death, even to the death of the Cross. For which cause God also hath exalted Him, and hath given Him a name which is above all names: that in the name of Jesus every knee should bow, of those that are in Heaven, on earth, and under the earth: and that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father (Phil. 2:5).
Even His Heavenly Father gave visible testimony: “This is my beloved Son, in whom I am well pleased” (Matt. 3:17 and Matt. 17:2). Nor did the earth fail to render homage to its Creator. At the moment of His death, “the veil of the temple was rent in two, from the top even to the bottom, and the earth quaked, and the rocks were rent. And the graves were opened, and many bodies of the saints that had slept arose, and coming out of the tombs after his resurrection, came into the holy city, and appeared to many” (Matt. 27:51)
It was a terrible claim for a man to make: the claim to be God. But Christ made that claim and held to it till the end. And every incident in His life and death bears witness to its truth and justice.
