The LORD is great in Zion; and he is high above all the people.

Augustine of Hippo
4. "The Lord is great in Sion, and high above all people" (ver. 2). ...He whom I spoke to thee of as above the Cherubims, is great in Sion. Ask thou now, what is Sion? We know Sion to be the city of God. The city of Jerusalem is called Sion; and is so called according to a certain interpretation, for that Sion signifieth watching, that is, sight and contemplation; for to watch is to look forward to, or gaze upon, or strain the eyes to see. Now every soul is a Sion, if it trieth to see that light which is to be seen. For if it shall have gazed upon a light of its own, it is darkened; if upon His, it is enlightened. But, now that it is clear that Sion is the city of God; what is the city of God, but the Holy Church? For men who love one another, and who love their God who dwelleth in them, constitute a city unto God. Because a city is held together by some law; their very law is Love; and that very Love is God: for openly it is written, "God is Love." He therefore who is full of Love, is full of God; and many, full of love, constitute a city full of God. That city of God is called Sion; the Church therefore is Sion. In it God is great. ...
5. Do ye imagine, brethren, that they whose instruments re-echoed yesterday, are not angry with our fastings? But let us not be angry with them, but let us fast for them. For the Lord our God who sitteth in us hath said, He hath Himself commanded us to pray for our enemies, to pray for them that persecute us: and as the Church doth this, the persecutors are almost extinct. ...The drunken man doth not offend himself, but he offendeth the sober man. Show me a man who is at last happy in God, liveth gravely, sigheth for that everlasting peace which God hath promised him; and see that when he hath seen a man dancing to an instrument, he is more grieved for his madness, than for a man who is in a frenzy from a fever. If then we know their evils, considering that we also have been freed from those very evils, let us grieve for them; and if we grieve for them, let us pray for them; and that we may be heard, let us fast for them. For we do not keep our own fasts in their holidays. Different are the fasts which we celebrate through the days of the approaching Passover, through different seasons which are fixed for us in Christ: but through their holidays we fast for this reason, that when they are rejoicing, we may groan for them. For by their joy they excite our grief, and cause us to remember how wretched they are as yet. But since we see many freed thence, where we also have been, we ought not to despair even of them. And if they are still enraged, let us pray; and if still a particle of earth that hath remained behind be stirred up against us, let us continue in lamentation for them, that to them also God may grant understanding, and that with us they may hear those words, in which we are at this moment rejoicing.
