In his retreat reflections using the Oblate Constitutions and Rules, Eugene copied out some of the passages of the Rule that he wished to keep before his eyes regularly in the future as a reminder. It is the exemplary quality of the Oblate that he keeps returning to.
And above all, the missions. The Constitutions come back to it again and again and rightly so as missions are the first and principal end of the Institute. So I do not think that it is necessary to insist on this point: Since the missions are one of the principal ends of the Institute, all will strive principally to fulfill this task well. (Art. 1, parag. 1, Regarding the Missions).
The whole should be read, but note the passage: Above all the members of the Institute will be intent on not giving even the appearance of bad example, and they will behave in such a way as to be always venerated by the people… (Art. 25, para. 1, Regarding the Missions).
That is not all: Since the end of the Institute is not only to give missions, but also to replace, insofar as our weak means permit, the religious orders and to repair the evils that have crept in among the clergy, all should be persuaded that it is easier to achieve this end by example than by words. Hence, we must convince ourselves that it is indispensable that we should practice all the virtues, and not be unacquainted with any of them. (Art. I, Preaching).
Firmly established on the foundation of the virtues, all the members of the Institute will devote themselves to perform any good work that may be prescribed by obedience. (art. 2, ibid.).
