Mediator between God and men._
And hence that true Mediator, in so far as, by assuming the form of a
servant, He became the Mediator between God and men, the man Christ
Jesus, though in the form of God He received sacrifice together with
the Father, with whom He is one God, yet in the form of a servant He
chose rather to be than to receive a sacrifice, that not even by
this instance any one might have occasion to suppose that sacrifice
should be rendered to any creature. Thus He is both the Priest who
offers and the Sacrifice offered. And He designed that there should
be a daily sign of this in the sacrifice of the Church, which,
being His body, learns to offer herself through Him. Of this true
Sacrifice the ancient sacrifices of the saints were the various and
numerous signs; and it was thus variously figured, just as one thing
is signified by a variety of words, that there may be less weariness
when we speak of it much. To this supreme and true sacrifice all
false sacrifices have given place.
