Compare vi. 6:  ὁ γεννηθεὶς ἀπαθῶς.  The importance attached to the assertion of a “passionless generation” arose from the objections offered by Eusebius of Nicomedia and others to the word ὁμοούσιος when proposed by Constantine at Nicæa.  We learn from Eusebius of Cæsarea (Epist ad suæ parœciæ homines, § 4) that the Emperor himself explained that the word was used “not in the sense of the affections (πάθη) of bodies,” because “the immaterial, and intellectual, and incorporeal nature could not be the subject of any corporeal affection.”  Again, in § 7, Eusebius admits that “there are grounds for saying that the Son is ‘one in essence’ with the Father, not in the way of bodies, nor like mortal beings, for He is not such by division of essence, or by severance, no, nor by any affection, or alteration, or changing of the Father’s essence and power.”  (See the next note.)
