124. It is not the term itself, then, but
its force and consequences, that they shun, because they will not
confess the Son of God to be true [God]. Or to be the
true Son of God, Son by nature, not by adoption. For though the process of the divine
generation cannot be comprehended in human language, still the Fathers
judged that their faith might be fitly distinguished by the use of such
a term, as against that of “ἑτεροούσιος
,” following the authority of the prophet, who saith:
“Who hath stood in the truth (substantia) of the Lord, and
seen His Word?” Jer. xxiii. 18. Arians,
therefore, admit the term “substance” when it is used so as
to square with their blasphemy; contrariwise, when it is adopted in
accordance with the pious devotion of the faithful, they reject and
dispute against it.
