In 1625, St. Vincent and three priests pledged to, in his own words, “…to live together as a Congregation… and to devote ourselves to the salvation of the poor country folk.” The Congregation of the Mission is later approved in the Papal Bull Salvatoris Nostri. It is affirmed that the Congregation was founded for the evangelization of the poor and must ensure the founding of Confraternities of Charity so that the poor are served and that lay people are included in the evangelization.
