Clement: The One is infinite

 “[...]since the first principle (ἀρχὴ) of everything is difficult to find out
(δυσεύρετος), the absolutely first and oldest principle (πρώτη καὶ
πρεσβυτάτη ἀρχὴ), which is the cause of all other things being and having
been, is difficult to exhibit (δύσδεικτος). For how can that be expressed
which is neither genus, nor difference, nor species, nor individual, nor
number; nay more, is neither an event, nor that to which an event happens?
No one can rightly express Him wholly. For on account of His greatness He
is ranked as the All, and is the Father of the universe. Nor are any parts to
be predicated of Him. For the One is indivisible (ἀδιαίρετον γὰρ τὸ ἕν); wherefore also it is infinite (ἄπειρον), not considered with reference to
inscrutability (ἀδιεξίτητον), but with reference to its being without
dimensions (ἀδιάστατον), and not having a limit (μὴ ἔχον πέρας). And
therefore it is without form and name (ἀσχημάτιστον καὶ ἀνωνόμαστον).” (Str. 5.12.81.4, pp. 463-464)
