This mystery was hidden from men, but not from
the Church in heaven, which is contained in the principalities and
powers who knew it "from all ages, but not before all ages: because
the Church was at first there, where after the resurrection this
Church composed of men will be gathered together."

It can also be explained otherwise that "what is hidden, is known by
the angels, not only in God, but also here where when it takes place
and is made public," as Augustine says further on (Gen. ad lit. v,
19). Thus when the mysteries of Christ and the Church were fulfilled
by the apostles, some things concerning these mysteries became
apparent to the angels, which were hidden from them before. In this
way we can understand what Jerome says (Comment. in Ep. ad
Eph.)--that from the preaching of the apostles the angels learned
certain mysteries; that is to say, through the preaching of the
apostles, the mysteries were realized in the things themselves: thus
by the preaching of Paul the Gentiles were converted, of which
mystery the Apostle is speaking in the passage quoted.

Reply Obj. 2: The apostles were instructed immediately by the Word of
God, not according to His Divinity, but according as He spoke in His
human nature. Hence the argument does not prove.

Reply Obj. 3: Certain men in this state of life are greater than
certain angels, not actually, but virtually; forasmuch as they have
such great charity that they can merit a higher degree of beatitude
than that possessed by certain angels. In the same way we might say
that the seed of a great tree is virtually greater than a small tree,
though actually it is much smaller.

THIRD ARTICLE [I, Q. 117, Art. 3]

Whether Man by the Power of His Soul Can Change Corporeal Matter?

Objection 1: It would seem that man by the power of his soul can
change corporeal matter. For Gregory says (Dialog. ii, 30): "Saints
work miracles sometimes by prayer, sometimes by their power: thus
Peter, by prayer, raised the dead Tabitha to life, and by his reproof
delivered to death the lying Ananias and Saphira." But in the working
of miracles a change is wrought in corporeal matter. Therefore men,
by the power of the soul, can change corporeal matter.

Obj. 2: Further, on these words (Gal. 3:1): "Who hath bewitched you,
that you should not obey the truth?" the gloss says that "some have
blazing eyes, who by a single look bewitch others, especially
children." But this
