Whether any procession in God can be called generation?

Objections

Objection 1 : It would seem that no procession in God can be called generation. For generation is change from non-existence to existence, and is opposed to corruption; while matter is the subject of both. Nothing of all this belongs to God. Therefore generation cannot exist in God.
Objection 2 : Further, procession exists in God, according to an intelligible mode, as above explained (Article [1]). But such a process is not called generation in us; therefore neither is it to be so called in God.
Objection 3 : Further, anything that is generated derives existence from its generator. Therefore such existence is a derived existence. But no derived existence can be a self-subsistence. Therefore, since the divine existence is self-subsisting (Question [3], Article [4]), it follows that no generated existence can be the divine existence. Therefore there is no generation in God.
