Whether religious who are raised to the episcopate are bound to religious observances?

Objections

Objection 1 : It would seem that religious who are raised to the episcopate are not bound to religious observances. For it is said (XVIII, qu. i, can. Statutum) that a "canonical election loosens a monk from the yoke imposed by the rule of the monastic profession, and the holy ordination makes of a monk a bishop." Now the regular observances pertain to the yoke of the rule. Therefore religious who are appointed bishops are not bound to religious observances.
Objection 2 : Further, he who ascends from a lower to a higher degree is seemingly not bound to those things which pertain to the lower degree: thus it was stated above (Question [88], Article [12], ad 1) that a religious is not bound to keep the vows he made in the world. But a religious who is appointed to the episcopate ascends to something greater, as stated above (Question [84], Article [7]). Therefore it would seem that a bishop is not bound to those things whereto he was bound in the state of religion.
Objection 3 : Further, religious would seem to be bound above all to obedience, and to live without property of their own. But religious who are appointed bishops, are not bound to obey the superiors of their order, since they are above them; nor apparently are they bound to poverty, since according to the decree quoted above (Objection [1]) "when the holy ordination has made of a monk a bishop he enjoys the right, as the lawful heir, of claiming his paternal inheritance." Moreover they are sometimes allowed to make a will. Much less therefore are they bound to other regular observances.
