Consummatum est

Consummatum est. J-J Tissot

Saint Luke - Chapter 23

[46] Et clamans voce magna Jesus ait : Pater, in manus tuas commendo spiritum meum. Et haec dicens, expiravit.
And Jesus crying out with a loud voice, said: Father, into thy hands I commend my spirit. And saying this, he gave up the ghost.

Saint John - Chapter 19

[30] Cum ergo accepisset Jesus acetum, dixit : Consummatum est...
Jesus therefore, when he had taken the vinegar, said: It is consummated...

From The Life of Our Lord Jesus Christ, by J-J Tissot (1897)

This last cry was one alike of obedient submission and of triumph.  In one brief, telling sentence it summed up the whole of the work of Jesus Christ as foreshadowed by the various types and foretold by the prophecies of the Old Testament  fulfilled.  It is the final completion of the Covenant between the Son of Man and God the Father, and between them and the human race.  All is finished now!  The work is done; the prophecies are accomplished.  There are no more insults to be submitted to now, no more tortures to endure; the Man of Sorrows has gone through all the suffering to which He was fore- doomed, and, humanity being through His sacrifice reconciled to God, there is nothing left for Him to do but to die.  It is, then, after this supreme moment that He rallies His strength for an instant to proclaim to the world in a thrilling voice: 

"It is finished."

Totus tuus ego sum 

Et omnia mea tua sunt;

Tecum semper tutus sum:
Ad Jesum per Mariam
