Jesus is the…

[Jesus] is the Bread sown in the virgin, leavened in the Flesh, molded in His Passion, baked in the furnace of the Sepulchre, placed in the Churches, and set upon the Altars, which daily supplies Heavenly Food to the faithful.
–Saint Peter Chrysologus (c. 380-450)

We offer the sacrifice…

So, since Christ died for us, out of love, it follows that, when we offer the sacrifice in commemoration of his death, we are asking for love to be given us by the coming of the Holy Spirit. We beg and we pray that just as through love Christ deigned to be crucified for us, so we may receive the grace of the Holy Spirit. And we ask that by that grace the world should be a dead thing in our eyes and we should be dead to the world, crucified and dead.
–Saint Fulgentius of Ruspe (Fifth — Sixth Century)

The gift of love…

What the gift of love gives us is the chance to become in truth what we celebrate as a mystery in the sacrifice.
–Saint Fulgentius of Ruspe (Fifth — Sixth Century)
