Crucem Tuam Adoremus Domine.....

.....'Et resurrectionem tuam ladamus, et glorificamus. Ecce enim propter lignum venit gaudium mundi.'
We adore thy glorious Cross, and we praise thy ressurection. For behold, by the
wood of the cross hath joy come into the world.

Tird antipon, Lauds of Good Friday.

"For I have spied unrighteousness and strife in the city. Give heed now to the glory of the Cross itself. On the brow of kings is now placed that Cross, which once enemies did deride. Effect hath proven strength. He hath subdued the world, not with a sword, but with Wood. The Wood of the Cross seemed a worthy object of scorn to his enemies ; and standing before that very Wood, they wagged their heads, saying, If thou be the Son of God, come down from the Cross! Thus did he stretch forth his hands to a disobedient and gainsaying people. If he is just who doth live by faith, then is he unrighteous who hath not faith. Wherefore, when he saith : Unrighteousness : understand that it is the disobedience of unbelief. The Lord then saw unrighteousness and strife in the city, and stretched out his hands unto an unbelieving and gainsaying people. And yet, looking upon the very same, he saith : Father, forgive them, for they know not what they do."
-S.Augustine.
