Reflection:

1. St. Vincent knew from experience of the importance to have support when you want to achieve something. He knew it when the negotiations for the recognition of the “small” (compared to the “great Jesuit”) Company began in Rome. He knew, moreover, by the number of recommendations that came to him (as a member of the Council of awareness of Queen Margaret) when he had to propose someone to the Holy See to the appointment of a bishop…  Human supports, obviously, but, we know he also trusted the divine support, the Holy Trinity.
2. The first of the obligations St. Vincent asked his missionaries was to “celebrate this feast with great devotion.” We can easily understand the term “celebrate” in the sense of “commemorate an event, especially if a ‘party/feast’ or other event alike is organized.” More difficult to understand is how to do it “with great devotion.” I would translate it with “being noticed by the rest.” Truthfully, we do not try to “understand” the mystery; but, even so, the “mystery” is to be celebrated with songs, laughter and celebration.
3. The second of the obligations is “teaching” this mystery. Difficult task: it is impossible to understand and difficult to believe in the Father, the Son and the Holy Spirit; so, how can we teach it?
4. Third and last obligation: this teaching must be done “at all times,” “early and late.” This may very well be one of Vincent’s deepest thoughts and convictions, an interpretative key of the Vincentian Mission. The strength of expression and finding it in other texts allows us to say so. We would have, thus, one of the key lines in the life of the Vincentian family.
