What the Valentinian προβολὴ was is described in Epiph. Hær. 31, 13 [but see D.C.B. iv. 1086 sqq.] Origen protests against the notion of προβολή, Periarch. iv. p. 190, and Athanasius Expos. §1. The Arian Asterius too considers προβολὴ to introduce the notion of τεκνογονία, Euseb. contr. Marc. i. 4. p. 20. vid. also Epiph. Hær. 72. 7. Yet Eusebius uses the word προβάλλεσθαι. Eccl. Theol. i. 8. On the other hand Tertullian uses it with a protest against the Valentinian sense. Justin has προβληθὲν γέννημα, Tryph. 62. And Nazianzen calls the Almighty Father προβολεὺς of the Holy Spirit. Orat. 29. 2. Arius introduces the word here as an argumentum ad invidiam. Hil. de Trin. vi. 9.
