Orth. -Then there are many things which He cannot do, for there are many kinds of transgression.
Eran. -Nothing of this kind can be wished or done by God.
Orth. -Nor can those things which are contrary to the divine nature.
Eran. -What are they?
Orth. -As, for instance, we have learnt that God is intelligent and true Light.
Eran. -True.
Orth. -And we could not call Him darkness or say that He wished to become, or could become, darkness.
Eran. -By no means.
Orth. -Again, the Divine Scripture calls His nature invisible.
Eran. -It does.
Orth. -And we could never say that It is capable of being made visible.
Eran. -No, surely.
Orth. -Nor comprehensible.
Eran. -No; for He is not so.
Orth. -No; for He is incomprehensible, and altogether unapproachable.
Eran. -You are right.
Orth. -And He that is could never become non-existent.
Eran. -Away with the thought!
Orth. -Nor yet could the Father become Son.
Eran. -Impossible.
Orth. -Nor yet could the unbegotten become begotten.
Eran. -How could He.
Orth. -And the Father could never become Son?
Eran. -By no means.
Orth. -Nor could the Holy Ghost ever become Son or Father.
