It is true that the
Nicene Council is not named here, but the allusion is obvious.
The Conservatives had actually objected to the novelty of the Creed;
and the Arians had, as Hilary goes on to say, used the pretext of
novelty to destroy the Gospel. The Council of Nicæa was
thirty-five years before, and is very accurately described as a
‘Synod of our fathers.’
