It remains for us to show how in accordance with the affirmation of
Catholic belief Christ consists at once in and of both natures.
The statement that a thing consists of two natures bears two meanings; one, when we say that anything is a union of two natures, as e.g. honey and water, where the union is such that in the combination, however the elements be confounded, whether by one nature changing into the other, or by both mingling with each other, the two entirely disappear. This is the way in which according to Eutyches Christ consists of two natures.
The other way in which a thing can consist of two natures is when it is so combined of 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.
