cf. note on p. 27 and the distinction between δόγμα and κήουγμα in § 66. “The great objection which the Eastern Church makes to the Filioque is, that it implies the existence of two ἀρχαὶ in the godhead; and if we believe in δύο ἄναρχοι; we, in effect, believe in two Gods. The unity of the Godhead can only be maintained by acknowledging the Father to be the sole ᾽Αρχὴ or πηγὴ θεοτήτος, who from all eternity has communicated His own Godhead to His co-eternal and consubstantial Son and Spirit. This reasoning is generally true. But, as the doctrine of the Procession of the Spirit from the Father and the Son presupposes the eternal generation of the Son from the Father; it does not follow, that that doctrine impugns the Catholic belief in the Μία ᾽Αρχή.” Bp.
