Eleusius is criticised by Socrates II. 40, for disliking any attempt at a repudiation of the “Dedication” creed of 341, although the “Dedication” creed was little better than a repudiation of the Nicene creed. He was, in fact, a semi-Arian. But his vigorous opposition to the extreme form of Arianism and the hopefulness with which Hilary always regarded the semi-Arians, here invest him with a reputation for the “true knowledge of God.” In 381 he refused to accept the Nicene creed or take part in the Council of Constantinople.
