“We have one God because there is a single Godhead. Though there are three objects of belief . . . it is as if there were a single intermingling of light, which existed in three mutually connected Suns” (Gregory of Nazianzus, Oration 31, in On God and Christ, 127-128).
“It is just like three suns cleaving to each other without separation and giving out light mingled and conjoined into one” (John of Damascus, De fide orthodoxa 1.8).
