εὐσέβεια, ἀσέβεια, &c., here translated “religion, irreligion, religious, &c. &c.” are technical words throughout, being taken from S. Paul’s text, “Great is the mystery of godliness,” εὐσεβείας, i.e. orthodoxy. Such too seems to be the meaning of “godly admonitions,” and “godly judgments,” and “this godly and well-learned man,” in our Ordination Services. The Latin translation is “pius,” “pietas.” It might be in some respects suitably rendered by “devout” and its derivatives. On its familiar use in the controversy depends the blasphemous jest of Eudoxius, Arian Bishop of Constantinople, which was received with loud laughter in the Cathedral, and remained in esteem down to Socrates’ day, “The Father is ἀσεβὴς, as being without devotion, the Son εὐσεβὴς, devout, as paying devotion to the Father.” Socr. Hist. ii. 43. Hence Arius ends his Letter to Eusebius with ἀληθως εὐσέβιε. Theod. Hist. i. 4.
