Whether a bishop may lawfully forsake the episcopal cure, in order to enter religion?

❌ Objection 1 : It seems that a bishop cannot lawfully forsake his episcopal cure in order to enter religion. For no one can lawfully pass from a more perfect to a less perfect state; since this is "to look back," which is condemned by the words of our Lord (Lk. 9:62), "No man putting his hand to the plough, and looking back, is fit for the kingdom of God." Now the episcopal state is more perfect than the religious, as shown above (Question [184], Article [7]). Therefore just as it is unlawful to return to the world from the religious state, so is it unlawful to pass from the episcopal to the religious state.

❌ Objection 2 : Further, the order of grace is more congruous than the order of nature. Now according to nature a thing is not moved in contrary directions; thus if a stone be naturally moved downwards, it cannot naturally return upwards from below. But according to the order of grace it is lawful to pass from the religious to the episcopal state. Therefore it is not lawful to pass contrariwise from the episcopal to the religious state.

❌ Objection 3 : Further, in the works of grace nothing should be inoperative. Now when once a man is consecrated bishop he retains in perpetuity the spiritual power of giving orders and doing like things that pertain to the episcopal office: and this power would seemingly remain inoperative in one who gives up the episcopal cure. Therefore it would seem that a bishop may not forsake the episcopal cure and enter religion.
