[ Apaugasma ]

 RADIANCE or shine. This is St. Paul's word, Hebr. i. 3, taken from Wisdom vii. 26, and suggesting the "Light from Light" of the Nicene Creed. It is the familiar illustration used by Athan. to convey the idea of the Divine Sonship, as consubstantial and from eternity. He sometimes uses the image of fire, Orat. iv. § 2 and 10, but it is still fire and its radiance . However, we find the illustration of fire from fire, Justin. Tryph. 61, Tatian. contr. Græc. 5. At this early day the illustration of radiance might have a Sabellian bearing, as that of fire in Athan.'s had an Arian. Hence Justin protests against those who considered the Son as "like the sun's light in the heaven," which "when it sets, goes away with it," whereas it is as "fire kindled from fire." Tryph. 128. Athenagoras, however, like Athanasius, says "as Light from Fire," using also the word [ aporrhoia ], effluence . Vid. also Orig. Periarchon, i. 2, n. 4. Tertull. Apol. 21. Theogn. ap. Athan. Decr. § 25.
