Apostolate is a vital aspect of the missionary activity of the Church.

As a gift of the Holy Spirit, every charism finds its proper expression in an apostolate necessary for the building of the Kingdom of God. As an expression of their charism, the Rogationists dedicate their lives in the apostolate in favor of the poor. In various places throughout the world, the Congregation has established orphanages, health and nutrition centers, schools for the deaf and mute, technical-vocational schools, scholarship programs for poor children, centers for professional management, centers for relief and assistance, parishes and oratories.
