3 “Our feet were standing in the courts of Jerusalem”...Consider what you will be there; and although you are as yet on the road, place this before your eyes, as if you were already standing, as if you were already rejoicing without ceasing among the Angels; as if that which is written were realized in you: “Blessed are they that dwell in Your house; they will be always praising You.” “Our feet stood in the courts of Jerusalem.” What Jerusalem? This earthly Jerusalem also is wont to be called by the name: though this Jerusalem is but the shadow of that.
And what great thing is it to stand in this Jerusalem, since this Jerusalem has not been able to stand, but has been turned into a ruin? Does then the Holy Spirit pronounce this, out of the kindled heart of the loving Psalmist, as a great thing? Is not it that Jerusalem, unto whom the Lord said, “O Jerusalem, Jerusalem, you that killest the Prophets,” etc. What great thing then did he desire; to stand among those who slew the Prophets, and stoned them that were sent unto them? God forbid that he should think of that Jerusalem, who so loves, who so burns, who so longs to reach that Jerusalem, “our Mother,” of which the Apostle says, that She is “eternal in the Heavens.”
