The observance of the Rule of Saint Benedict procured for Benedictine monks at an early period the name of "regulars".

But the Decretals of Gregory IX, promulgated 5 September 1234, use the word "regularis" in a more general sense, in book III, ch.

xxxv "De statu monachorum et canonicorum regularium" the distinction returns, disappearing in the corresponding book and chapter of the Decretals of Boniface VIII (3 March 1298),[6][1] which is entitled merely "De statu regularium" and reappearing in the collection of Clementines (25 Oct., 1317) but with the conjunction vel, which indicates the resemblance between them.

Those who have taken simple vows in the Society of Jesus were also regulars in the proper sense according to the Constitution "Ascendente" of Pope Gregory XIII.
