glory, and a commemoration of the two. That is the Catholic faith, which
comprehends these two truths which seem opposed.
The heresy of to-day, not conceiving that this Sacrament contains at the
same time both the presence of Jesus Christ and a type of Him, and that it
is a sacrifice and a commemoration of a sacrifice, believes that neither of
these truths can be admitted without excluding the other for this reason.
They fasten to this point alone, that this Sacrament is typical; and in this
they are not heretics. They think that we exclude this truth; hence it comes
