be unstable, going to and fro from one thing to another; but we shall
see all we know at one glance."

_I answer that,_ What is seen in the Word is seen not successively, but
at the same time. In proof whereof, we ourselves cannot know many
things all at once, forasmuch as understand many things by means of
many ideas. But our intellect cannot be actually informed by many
diverse ideas at the same time, so as to understand by them; as one
body cannot bear different shapes simultaneously. Hence, when many
things can be understood by one idea, they are understood at the same
time; as the parts of a whole are understood successively, and not all
at the same time, if each one is understood by its own idea; whereas
if all are understood under the one idea of the whole, they are
understood simultaneously. Now it was shown above that things seen in
God, are not seen singly by their own similitude; but all are seen by
the one essence of God. Hence they are seen simultaneously, and not
successively.

Reply Obj. 1: We understand one thing only when we understand by one
idea; but many things understood by one idea are understood
simultaneously, as in the idea of a man we understand "animal" and
"rational"; and in the idea of a house we understand the wall and the
roof.

Reply Obj. 2: As regards their natural knowledge, whereby they know
things by diverse ideas given them, the angels do not know all things
simultaneously, and thus they are moved in the act of understanding
according to time; but as regards what they see in God, they see all
at the same time.

ELEVENTH ARTICLE [I, Q. 12, Art. 11]

Whether Anyone in This Life Can See the Essence of God?

Objection 1: It seems that one can in this life see the Divine
essence. For Jacob said: "I have seen God face to face" (Gen. 32:30).
But to see Him face to face is to see His essence, as appears from the
words: "We see now in a glass and in a dark manner, but then face to
face" (1 Cor. 13:12).

Obj. 2: Further, the Lord said to Moses: "I speak to him mouth to
mouth, and plainly, and not by riddles and figures doth he see the
Lord" (Num. 12:8); but this is to see God in His essence. Therefore it
is possible to see the essence of God in this life.

Obj. 3: Further, that wherein we know all other things, and whereby
we judge of other things, is known in itself to us. But even now we
know all things in God; for Augustine says (Confess. viii): "If
