When Eugene had written to Henri Tempier to invite him to join the Missionaries, he had said:
We will live together in one house, that which I have bought, under a Rule we shall adopt with common accord and for which we will draw the elements from the statutes of St. Ignatius, of St. Charles for his Oblates, of St. Philip Neri, of St. Vincent de Paul and of the Blessed Liguori. Happiness awaits us in this holy Society which will have but one heart and soul.
Letter to Henri Tempier, 9 October 1815, O.W. VI n. 4.
The Rule which Eugene put together in September 1818 at St Laurent drew from the source of the Rules of other religious Congregations, especially that of St. Alphonsus Liguori who preached missions from the perspective of Christ the Redeemer, also of Saints Ignatius, Charles Borromeo, Philip Neri, Vincent de Paul, as well as the Sulpicians.
All these figures were admired by Eugene for their zeal either in mission preaching, or devotion to the poor, or ministry to youth, or foreign missions, or pastoral care etc. Eugene built on solid rock here as well because he made use of Rules that had been approved by the Church, and which contained the lived experience of other and older Congregations.
The sections which Eugene adapted and made his own clearly expressed his own spirit in a tried and tested manner, and thus together with the Missionaries of Provence whose Rule it was, we need to see these Rules as their own reality which expressed the spirit with which God led them to respond to God’s call.
The Rule was the Gospel reflected for the Mazenodian family in the light of our charism.
