Psalms 149:2

"Let Israel rejoice in Him who made Him" [Psalm 149:2]. What is, "Israel"? "Seeing God." He who sees God, rejoices in Him by whom he was made. What is it then, brethren? We have said that we belong to the Church of the saints: do we already see God? And how are we Israel, if we see not? There is one kind of sight belonging to this present time; there will be another belonging to the time hereafter: the sight which now is, is by faith; the sight which is to be will be in reality. If we believe, we see; if we love, we see: see what? God. Ask John: "God is love;" [1 John 4:16] let us bless His holy Name, and rejoice in God by rejoicing in love. Whoso has love, why send we him afar to see God? Let him regard his own conscience, and there he sees God...."And let the sons of Sion exult in their King." The sons of the Church are Israel. For Sion indeed was one city, which fell: amid its ruins certain saints dwelt after the flesh: but the true Sion, the true Jerusalem (for Sion and Jerusalem are one), is "eternal in the heavens," [2 Corinthians 5:1] and is "our mother." [Galatians 4:26] She it is that has given us birth, she is the Church of the saints, she has nourished us, she, who is in part a pilgrim, in part abiding in the heavens. In the part which abides in heaven is the bliss of angels, in the part which wanders in this world is the hope of the righteous. Of the former is said, "Glory to God in the highest;" of the latter, "and on earth peace to men of good will." [Luke 2:14] Let those then who, being in this life, groan, and long for their country, run by love, not by bodily feet; let them seek not ships but wings, let them lay hold on the two wings of love. What are the two wings of love? The love of God, and of our neighbour. For now we are pilgrims, we sigh, we groan. There has come to us a letter from our country: we read it to you. "And the sons of Sion shall exult in their King." The Son of God, who made us, was made one of us: and He rules us as our King, because He is our Creator, who made us. But He by whom we were made is the same as He by whom we are ruled, and we are Christians because He is Christ. He is called Christ from Chrism, that is, Anointing....Give to the Priest somewhat to offer. What could man find which he could give as a clean victim? What victim? What clean thing can a sinner offer? O unrighteous, O sinful man, whatever you offer is unclean, and somewhat that is clean must be offered for you....Let then the Priest that is clean offer Himself, and cleanse you. This is what Christ did. He found in man nothing clean for Him to offer for man: He offered Himself as a clean Victim. Happy Victim, true Victim, spotless Offering. He offered not then what we gave Him; yea rather, He offered what He took of us, and offered it clean. For of us He took flesh, and this He offered. But where took He it? In the womb of the Virgin Mary, that He might offer it clean for us unclean. He is our King, He is our Priest, in Him let us rejoice.
