Explanation of the Second Article
S. Tell me now about the second article, namely, “And in Jesus Christ, His Son, Our Lord.”
T. God Almighty, about Whom the first article treats, has a true and natural Son, Whom we call Jesus Christ. So that you might understand how God begot this Son, take the similitude of a mirror. When someone gazes into a mirror, an image is immediately produced that is so like him that he cannot discover any difference, in as much as it not only reflects his countenance, but even represents individual movements, so that the image moves exactly in the way the man does. Such an image is so like the man without any labor, without time, without instrument yet it is formed suddenly and in a moment in the flash of an eye. Consider in the same arrangement that when God gazes upon the mirror of the God head with the eye of the intellect, immediately He forms an image similar to Himself, and because God directs His whole essence and nature to this image (which we cannot do by gazing), therefore this image is the true Son of God, even if our own image which we behold in the mirror is not our son. For that reason you have to gather how the Son of God is God, in the same way as the Father is God and the same God with God, because He is/has the same substance with the Father. Next, the Son is not younger than the Father, but was always just as the Father always was. Accordingly, He advanced from the only vision of God, and God always saw and regarded Himself at length, the Son of God was not begotten in time from the cooperation of a woman, nor from the vicious lust, or from other related imperfections, but only by God, only, as was said, from his vision and by the most pure eye of the Divine Intellect.
S. Why is the Son of God called Jesus Christ?
T. The name of Jesus means Savior, while Christ, because it is the last name, means High Priest and King of Kings, as we touched upon the explanation of the sign of the Cross, that the Son of God became man to redeem us in His blood and to restore us to eternal salvation. Therefore, after He became man, He took this name of Savior to himself, to show that He came to save man. He was also given the title of High Priest and Supreme King by the Father, all of which this name Christ designates, and by such a name we are called Christians.
S. Why do we remove our hat or genuflect whenever the name of Jesus is said, but we do not do this after we hear the name “God”?
T. The reason is because this name is proper to the Son of God, since all the rest are common; likewise, we are taught by this name how God, by becoming man for our sake, humbled Himself. Furthermore, we genuflect in an Act of Thanksgiving when we hear this name. Not only do we men genuflect, but even the angels of God in heaven, and the demons in hell, on account of this name the former from voluntary love, the latter are compelled by fear. God also willed that all rational creatures should genuflect in the presence of His Son, seeing that He Himself so bent Himself and humbled Himself even to death of the Cross.
S. Why is Jesus Christ called Our Lord?
T. Because He, together with the Father, created us, therefore He is our Patron and Lord just as the Father. More to the point, He freed us from the power and Captivity of the devil by bitter torments and His Passion, which we will speak of in a little while.
