The Missionary Union of Priests and Religious: Lay People in Common Cause with Religious and Pastoral Leaders.
Founded in 1906, the Missionary Union is a spiritual apostolate. Unlike the other three Pontifical Mission Societies, this mission society does not collect or distribute funds. Its purpose is to educate and inspire priests, men and women religious, pastoral leaders, and those responsible for catechesis and religious education so that they may better animate others to share their faith and to be missionaries themselves, supporting also the missionary work of the Church worldwide.
There are a number of local and national organizations that help connect lay Catholics to mission opportunities in the United States and abroad. Contact the Catholic Volunteer Network, a national membership organization of Christian volunteer and mission programs that fosters and promotes full-time national and international service opportunities for people of all backgrounds, ages, and skills: www.catholicvolunteernetwork.org. Member programs have volunteer positions available in all fifty states, the District of Columbia, and in over 100 countries across the world, ranging from a week to a summer to a several-year commitment and everything in between.
