Missionary Union of Priests and Religious
In 1916, Fr. Paolo Manna, a PIME* missionary established the Missionary Union of Priests and Religious to focus on what is needed to be missionary and to encourage others in missionary work. This spiritual apostolate continues to address itself today to those called to bring Catholics to a better understanding of their baptismal responsibility for the Church's missionary work -- priests, religious, seminarians, pastoral leaders, and those engaged in catechesis and religious education. In fact, the success of the efforts of the other three mission societies is linked to the vitality of the Missionary Union, because it is through this work that the missionary spirit of prayer and sacrifice is developed and nurtured.
