It is impossible for any creature which experiences the Beatific Vision, seeing God “face to face,” to reject God, because such a creature would possess perfect happiness.
So the angels must have been created in a state short of the Beatific Vision.

I can’t offer an infallible interpretation of your Bible verses, but they have to be reconcilable with the theology, which is very sure.
Well, you say they have to be reconcilable with the theology, but I see no way for them to be reconciled. It seems to me that or the other must be wrong. Here’s something from the Catholic Encyclopedia that illustrates why:
“Pope Gregory divided the nine angelic orders into three choirs, the highest choir being: thrones, cherubim, and seraphim. Of the cherubim he says (Hom. in Ev., xxxiv, 10), that cherubim means “the fulness of knowledge, and these most sublime hosts are thus called, because they are filled with a knowledge which is the more perfect as they are allowed to behold the glory of God more closely”. This explanation of St. Gregory is ultimately derived from Philo’s similar statement, and was already combined with the Old Testament function of the cherubim by St. Augustine in his sublime comment on Ps., lxxix, 2, “Who sitteth upon the Cherubim”:
Cherubim means the Seat of the Glory of God and is interpreted: Fullness of Knowledge. Though we realize that cherubim are exalted heavenly powers and virtues; yet if thou wilt, thou too shalt be one of the cherubim. For if cherubim means, Seat of God, remember what the Scripture says: The soul of the just is the Seat of Wisdom.”

The phrase “covering cherub” implies even more intimacy and full knowledge of God than just a cherub, since these were the cherubim that were in direct contact with God, like his personal entourage. The covering cherubim are represented surrounding God’s throne, facing the Mercy Seat on the Ark of the Covenant, inside the Holy of Holies, demonstrating that they most certainly were “face to face” with God.
So, either the Bible is wrong, or the Catholic theology is wrong on this point, and the angels with the most direct, face to face contact with God could reject God, since that is exactly what Satan did.
