1. This title does not require a fresh consideration: for the meaning of, “to the end,” has already been sufficiently handled. Let us then look to the text itself of the Psalm, which to me appears to be sung against the heretics, who, by rehearsing and exaggerating the sins of many in the Church, as if either all or the majority among themselves were righteous, strive to turn and snatch us away from the breasts of the one True Mother Church: affirming that Christ is with them, and warning us as if with piety and earnestness, that by passing over to them we may go over to Christ, whom they falsely declare they have. Now it is known that in prophecy Christ, among the many names in which notice of Him is conveyed in allegory, is also called a mountain. We must accordingly answer these people, and say, “I trust in the Lord: how say ye to my soul, Remove into the mountains as a sparrow?” (ver. 1). I keep to one mountain wherein I trust, how say ye that I should pass over to you, as if there were many Christs? Or if through pride you say that you are mountains, I had indeed need to be a sparrow winged with the powers and commandments of God: but these very things hinder my flying to these mountains, and placing my trust in proud men. I have a house where I may rest, in that I trust in the Lord. For even “the sparrow hath found her a house,” and, “The Lord hath become a refuge to the poor.” Let us say then with all confidence, lest while we seek Christ among heretics we lose Him, “In the Lord I trust: how say ye to my soul, Remove into the mountains as a sparrow?”
