"becoming a slave of Christ means having been redeemed from servitude into freedom." (Marius Victorinus, On Galatians ??)

"God is therefore μὴ ὄν"

“Necessarily we say that through superiority and preeminence over τῶν ὄντων God is above all existence, above all life, above all knowledge, above every ὄν and the ὄντως ὄντα; indeed he is unknowable, infinite, invisible, without idea, insubstantial, inconceivable, and because transcendent, he is nothing of existents, and because he is above existents, he has nothing from existents. God is therefore μὴ ὄν.” (Marius Victorinus, Ad Cand. 13, 5–12 (SC 68, p. 148; tr. Clark, p. 70))

“Necessario per praelationem et per eminentiam τῶνὂντων deum dicemus supra omnem exsistentiam, supra omnem vitam, supra omnem cognosccntiam, supra omne ὂν et ὄντωςὄντα, quippe inintellegibile, infinitum, invisibile, sine intellectu, insubstantiale, inio cognoscibile, et quod super omnia, nihil de his quae sunt, ct quoniam supra quae sunt, nihil ex his quae sunt. Μὴὂν ergo deus est”
