f two that the elements of which it is said to be combined
continue without changing into each other, as when we say that a crown
is composed of gold and gems. Here neither is the gold converted into
gems nor is the gem turned into gold, but both continue without
surrendering their proper form.

Things then like this, composed of various elements, we say consist also
in the elements of which they are composed. For in this case we can say
that a crown is composed of gems and gold, for gems and gold are that in
which the crown consists. For in the former mode of composition honey
and water is not that in which the resulting union of both consists.

Since then the Catholic Faith confesses that both natures continue in
Christ and that they both remain perfect, neither being transformed into
the other, it says with right that Christ consists both in and of the
two natures; _in_ the two because both continue, _of_ the two
because the One Person of Christ is formed by the union of the two
continuing natures.

But the Catholic Faith does not hold the union of Christ out of two
natures according to that sense which Eutyches puts upon it. For the
interpretation of the conjunction out of two natures which he adopts
forbids him to confess consistence in two or the continuance of the two
either; but the Catholic adopts an interpretation of the consistence out
of two which comes near to that of Eutyches, yet keeps the
interpretation which confesses consistence in two.

"To consist of two natures" is therefore an equivocal or rather a
doubtful term of double meaning denoting different things; according to
one of its interpretations the substances out of which the union is said
to have been composed do not continue, according to another the union
effected of the two is such that both natures continue.

When once this knot of doubt or ambiguity has been untied, nothing
further can be advanced to shake the true and solid content of the
Catholic Faith, which is that the same Christ is perfect man and God,
and that He who is perfect man and God is One God and Son of Man, that,
however, quaternity is not added to the Trinity by the addition of human
nature to perfect Godhead, but that one and the same Person completes
the number of the Trinity, so that, although it was the manhood which
suffered, yet God can be said to have suffered, not by manhood becoming
Godhead
