For a Nephil character concept I was tossing around, I left out anything True Faith related; that's for mortal worshipers, not for direct agents of the divine. The target for that build was Soulfire, Mythic Strength and Speed, Physical Immunity (with lower values being taken as Toughness, never Recovery) with a Catch of divine power (including that of angels, fallen angels, and power loaned out to Emissaries of either) at a +3 (anyone who knows anything about angels knows that only God and each other can really hurt them, but getting your hands on Soulfire, Hellfire, or a weapon imbued by an angel or one of the Fallen is a bit trickier), and Wings. Incite Emotion (Terror, Ranged, Potent, Area Effect) might also be reasonable.
What you're looking at is really more of a saint than an angel, in my mind; one of the core traits of an angel is that it can't exercise free will without falling from grace. A proper saint should have, as you note, all of the True Faith powers, and likely also uses Soulfire. Inhuman attributes don't really seem appropriate.
