Vid. Orat. i. §38. The controversy turned on the question what was meant by the word ‘Son.’ Though the Arians would not allow with the Catholics that our Lord was Son by nature, and maintained that the word implied a beginning of existence, they did not dare to say that He was Son merely in the sense in which we are sons, though, as Athan. contends, they necessarily tended to this conclusion, directly they receded from the Catholic view. Thus Arius said that He was a creature, ‘but not as one of the creatures.’ Orat. ii. §19. Valens at Ariminum said the same, Jerom. adv. Lucifer. 18. Hilary says, that not daring directly to deny that He was God, the Arians merely asked ‘whether He was a Son.’ de Trin. viii. 3. Athanasius remarks upon this reluctance to speak out, challenging them to present ‘the heresy naked,’ de Sent. Dionys. 2. init. ‘No one,’ he says elsewhere, ‘puts a light under a bushel; let them shew the world their heresy naked.’ Ep. Æg. 18. vid. ibid. 10. In like manner, Basil says that (though Arius was really like Eunomius, in faith, contr. Eunom. i. 4) Aetius his master was the first to teach openly (φανερῶς), that the Father’s substance was unlike, ἀνόμοιος, the Son’s. ibid. i. 1. Epiphanius Hær. 76 p. 949. seems to say that the elder Arians held the divine generation in a sense in which Aetius did not, that is, they were not so consistent and definite as he. Athan. goes on to mention some of the attempts of the Arians to find some theory short of orthodoxy, yet short of that extreme heresy, on the other hand, which they felt ashamed to avow.
