Council of Trent
(1545-1563), Session
23
"In conformity with God's decree, sacrifice and
priesthood are
so related that both exist in
every law. Therefore, in the New
Testament, since the Catholic
Church has received the holy
and visible sacrifice of the
Eucharist according to the institution
of the Lord, it is likewise
necessary to acknowledge that there
is in the Church a new, visible,
and external priesthood, into
which the old priesthood was
changed. Moreover, Sacred
Scripture makes it clear that
this priesthood was instituted
by the same Lord our Savior, and
that the power of consecrating,
offering, and administering his
body and blood, and likewise
the power of remitting and of
retaining sins, was given to the
apostles and their successors in
the priesthood."
