Father Jean-Jacques Olier is the founder of the Sulpicians and an inspirational priest, as well as Catholic Author. In his earlier days he crossed paths with Saint Francis de Sales. Let us consider the details of his ordination: "On the 12th of March, 1633, M. Olier received the sub-diaconate, and on the 26th of the same month the diaconate; and, finally, on the 21st of May, being the Saturday before Trinity Sunday, he was ordained priest by M. Etienne Puget, Bishop of Dardania, who was also at the time Bishop Auxiliary of Metz and subsequently became Bishop of Marseilles. But, not content with making the ordinary retreat, he desired, like other good and pious priests, to employ some considerable time in "adorning" (to adopt M. Faillon's words) "the interior sanctuary of his heart before offering for the first time the Lamb without spot." Accordingly, he spent an entire month in a course of spiritual exercises, intermitting all other occupations."
