What our fathers said, the same say we, that the glory of the Father and of the Son is common; wherefore we offer the doxology to the Father with the Son.  But we do not rest only on the fact that such is the tradition of the Fathers; for they too followed the sense of Scripture, and started from the evidence which, a few sentences back, I deduced from Scripture and laid before you.  For “the brightness” is always thought of with “the glory,” Heb. i. 1.  cf. Aug. Ep. ii. ad Serap.:  “The Father is Light, and the Son brightness and true light.” “the image” with the archetype, 2 Cor. iv. 4. and the Son always and everywhere together with the Father; nor does even the close connexion of the names, much less the nature of the things, admit of separation.
