Hilary then makes a direct appeal to the Western
bishops. They might forget the contents of the word while
retaining the sound, but provided that the meaning was granted, what
objection could be made to the word? Was the word ὁμοιούσιον
free from all possible objections? Hilary (c. 72–75)
shews that really like means really equal.
Scripture is appealed to as proving the assertion that the Son is both
like God and equal to God. This essential likeness can alone
justify the statement that the Father and the Son are one.
It is blasphemous to
represent the similarity as a mere analogy. The similitude is a
similitude of proper nature and equality. The conclusion of the
argument is that the word ὁμοιούσιος,
if understood, leads us to the word ὁμοούσιος which
helps to guard it, and that it does not imply any separation between
the Persons of the Trinity.
