The Passion of Christ

It it truly meet and just, right and for our salvation, that we should at all times, and in all places, give thanks unto Thee, O holy Lord, Father almighty, everlasting God; Who didst establish the salvation of mankind on the tree of the Cross; that whence death came, thence also life might arise again, and that he, who overcame by the tree, by the tree also might be overcome: Through Christ our Lord. Through whom the Angels praise Thy Majesty, the Dominations worship it, the Powers stand in awe. The Heavens and the heavenly hosts together with the blessed Seraphim in triumphant chorus unite to celebrate it. Together with these we entreat Thee that Thou mayest bid our voices also to be admitted while we say with lowly praise.  (Preface of the Holy Cross for Passion Sunday)
