FIRST ARTICLE [II-II, Q. 188, Art. 1]
Whether There Is Only One Religious Order?
Objection 1: It would seem that there is but one religious order. For there can be no diversity in that which is possessed wholly and perfectly; wherefore there can be only one sovereign good, as stated in the First Part (Q. 6, AA. 2, 3, 4). Now as Gregory says (Hom. xx in Ezech.), "when a man vows to Almighty God all that he has, all his life, all his knowledge, it is a holocaust," without which there is no religious life. Therefore it would seem that there are not many religious orders but only one.
Obj. 2: Further, things which agree in essentials differ only accidentally. Now there is no religious order without the three essential vows of religion, as stated above (Q. 186, AA. 6, 7). Therefore it would seem that religious orders differ not specifically, but only accidentally.
