Moreover, one cannot speak of one compound thing made of two wills in the same
way as a subsistence is a composition of two natures. Firstly
because the compositions are of things in subsistence
(hypotasis), not of things viewed in a different category, not
in one proper to them πρῶτον μὲν,

ὑποστάσει
ὄντων, καὶ οὐ
τῶν ἑτέρῳ
λόγῳ, καὶ οὐκ

εἰσί.: and
secondly, because if we speak of composition of wills and energies, we
will be obliged to speak of composition of the other natural
properties, such as the uncreated and the created, the invisible and
the visible, and so on. And what will be the name of the will
that is compounded out of two wills? For the compound cannot be
called by the name of the elements that make it up. For otherwise
we should call that which is compounded of natures nature and not
subsistence. And further, if we say that there is one compound
will in Christ, we separate Him in will from the Father, for the
Father’s will is not compound. It remains, therefore, to
say that the subsistence of Christ alone is compound and common, as in
the case of the natures so also in that of the natural
properties.
