Whether the soul was made or was of God's substance?

Objections

Objection 1 : It would seem that the soul was not made, but was God's substance. For it is written (Gn. 2:7): "God formed man of the slime of the earth, and breathed into his face the breath of life, and man was made a living soul." But he who breathes sends forth something of himself. Therefore the soul, whereby man lives, is of the Divine substance.
Objection 2 : Further, as above explained (Question [75], Article [5]), the soul is a simple form. But a form is an act. Therefore the soul is a pure act; which applies to God alone. Therefore the soul is of God's substance.
Objection 3 : Further, things that exist and do differ are the same. But God and the mind exist, and in no way differ, for they could only be differentiated by certain differences, and thus would be composite. Therefore God and the human mind are the same.
