V. Adoramus te Christe et benedicimus tibi (We adore Thee, O Christ, and we bless Thee)
R. Quia per Crucem tuam redemisti mundum (For by Thy holy cross Thou hast redeemed the world.)
Everything has to be consummated. From this perspective we can also understand the threefold fall of Jesus. The imperfect and sinful world was to be redeemed in its entirety.
The threefold fall of Jesus reminds us of the threefold denial of His beloved disciple Peter.
