complementary expressions

From Ott's Fundamentals of Catholic Doctrine, p. 64:

The co-ordinating formula (filioque) and the subordinating formula (per filium) concur essentially, in so far as they both attest that both the Father and the Son are the Principle of the Holy Ghost and they also complement each other. While in the former the unicity and the indivisibility of the Principle are above all expressed, the latter effectively stresses that the Father is the Primitive Principle (cf. Augustine, De Trin. XV 17, 29: de quo procedit principlaliter), and that the Son as "God from God" is the Derived Principle, in so far as He, with His Essence, also receives the power of spiration from the Father. Cf. D 691.

Note to self: learn about the Filioque controversy.

omnipresence and transcendence

"Neither do I deny that God is so deeply present to everything . . . that it would be impossible for him but for his infinity not to be identified with them or, from the other side, impossible but for his infinity so to be present to them."

Hopkins

"I believe in one God"

God must be eternal if he is one; that is, only the being of which unqualified unity can be predicated can be eternal, for it would not possess its being in a series of moments but in a single act.
