Whether to be immutable belongs to God alone?

❌ Objection 1 : It seems that to be immutable does not belong to God alone. For the Philosopher says (Metaph. ii) that "matter is in everything which is moved." But, according to some, certain created substances, as angels and souls, have not matter. Therefore to be immutable does not belong to God alone.

❌ Objection 2 : Further, everything in motion moves to some end. What therefore has already attained its ultimate end, is not in motion. But some creatures have already attained to their ultimate end; as all the blessed in heaven. Therefore some creatures are immovable.

❌ Objection 3 : Further, everything which is mutable is variable. But forms are invariable; for it is said (Sex Princip. i) that "form is essence consisting of the simple and invariable." Therefore it does not belong to God alone to be immutable.
