The Catholic Home Missions Appeal Strengthens the Church from Alaska to Alabama. Next Sunday, May 5 all Catholics are invited to give to the Catholic Home Missions Appeal of the U.S. Conference of Catholic Bishops (USCCB). This annual collection supports dioceses in the United States and its territories where it is difficult to sustain basic, essential ministries because of challenges posed by geography, population, or economy. These basic pastoral services include Mass, the sacraments, religious education, and training for clergy and lay people to minister to the local faithful.
