​​​​​​​​​​​​​​​​St. John's Seminary

St. John's Seminary opened in September 1939​​ on land in Camarillo, California, that was donated to the archdiocese by Don Juan Camarillo. The seminary offers a post-college,​​ fully accredited theological academic program for men from the archdiocese and from other dioceses that do not have their own seminary. The seminary will celebrate its 75th anniversary during the 2014–2015 academic year. It continues to serve the needs of the Church through the education and continued formation of seminarians, priests, deacons, and lay ecclesial ministers.

In 1962 St. John's College opened, adding a four-year undergraduate degree for men considering the priesthood and seeking a seminary-based college experience. The college continued until 2003.

Men who aspire to the priesthood in the archdiocese now participate in the formation program offered to college-​​level men at the Juan Diego House of Formation in Gardena as well as in the programs offered at St. John's Seminary.

In addition to the archdiocesan formation programs, several religious orders have houses of formation within the archdiocese that are listed in the Archdiocese of Los Angeles Catholic Directory​.

Catholic Charities of Los Angeles Inc.

Catholic Charities of Los Angeles Inc. is the social service arm of the archdiocese. Its roots are in the early days of Los Angeles when Catholic women organized to provide immediate care for the homeless and poor through soup kitchens and food pantries. These groups were formally organized in 1919 and became the archdiocesan entity focused on meeting the immediate needs of families and initiating new service programs as required. Now Catholic Charities strives to find permanent solutions to crisis situations by offering clients the tools and resources they need to achieve greater self-reliance and stability in their lives. Services are provided to anyone who comes to the agency in need, regardless of race, ethnicity, gender, age, or religious belief.

Catholic Charities operates community centers and homeless shelters, as well as programs serving the poor that include food pantries, thrift stores, in-home services for homebound seniors, refugee resettlement, youth employment services, counseling, affordable before- and after-school child care, immigration assistance, preschool for children of low-income families, and temporary worker centers.

In addition, the agency oversees the Catholic Youth Organization, which coordinates interscholastic athletics for elementary schools of the Archdiocese of Los Angeles​.

Catholic Charities' operations are divided into five service areas that coincide with the pastoral regions of the archdiocese. This structure enables the agency to maintain a presence in communities with the greatest needs, while sharing common resources and administrative overhead.

Charitable gifts and donor support are critical components of funding. Annually, nearly half of the funding needs are met from donations or earnings on donations; about one-third of the funding is from government support or contracts and the balance is from services, sales, and other revenues.​

Catholic Cemeteries

The archdiocese operates 11 cemeteries that are owned by, overseen by, and subject to the canonical authority of the archbishop of Los Angeles and operated through separate units under the Archdiocesan Catholic Center​. The cemeteries are an important ministry of the archdiocese and an extension of our church community that serve parishes and the faithful as an ongoing sacred testament to the Church's belief in the resurrection of the body and as a holy place for prayer and consolation. Disposition rights may be purchased by Catholics and members of their families for burial in a grave (interment), crypt (entombment), or niche (inurnment)​. Ownership of the real property associated with the purchased disposition rights is retained by the archdiocese and each cemetery has various policies concerning visiting, interment, and services. The cemetery operations offer both pre-need arrangements​ for the purchase of disposition rights to graves, crypts, or niches while the faithful are alive and at-need arrangements at the time of death or burial.

Together in Mission

Together in Mission is an annual appeal program established in 1992 to reach out to the entire Catholic community of the archdiocese to raise money to preserve and support Catholic schools and parishes that would not survive economically without outside support. The appeal supports the work of the Church in providing the sacraments, ministries, Catholic education, and service programs throughout the archdiocese and allows parishes and schools to assist one another through the generosity and commitment of their parishioners. The program is governed by an advisory board of clergy and laity that allocates the available funds among the regions of the archdiocese; in turn, funds are then allocated within the region to benefit schools and parishes with the most need.

All funds collected through the Together in Mission program are restricted for use as subsidies for the designated parishes and schools. Annually each parish is given a fund-raising goal equal to 10 percent of parish offertory income for the prior fiscal year and that amount is used to plan for the annual gifts from Together in Mission. If the annual targets are surpassed, the excess is available for emergency grants. To encourage the parishes in their fund-raising efforts, when a parish exceeds its fund-raising goal, 100 percent of the excess is returned to it for its use.

Catholic Education Foundation

The Catholic Education Foundation (CEF) was founded in 1986 by Cardinal (then Archbishop) Roger Mahony. Mindful of the great tradition of Catholic schools as well as their escalating cost, he sought and received the support of leading members of the Los Angeles business and philanthropic leadership. The result is CEF, formed as a revocable trust under the incumbent archbishop with a board of clergy and business and philanthropic laity.

The purpose of CEF when it was founded was to preserve quality education in the Catholic schools, make schools as affordable as possible, and ensure that the schools were available to those who could not afford the cost, particularly inner-city children who were supported regardless of religious affiliation. Through the years, raising funds to sustain a tuition assistance program (TAP) has been the cornerstone of CEF's efforts. The majority of all tuition awards continues to be made to children attending the poorest subsidized schools of the archdiocese. In more recent years CEF also has engaged in follow-up studies of the recipients of funding to confirm the positive benefits of CEF efforts and has, on a selected basis, provided some funding for graduate studies for faculty in selected Catholic schools.

CEF has detailed protocols for applications and the review and administration of its TAP and other programs that are available annually and directly to schools and through the CEF website.

Pontifical Mission Societies: Society for the Propagation of the Faith

The Holy See has established four Pontifical Mission ​​​Societies: the Society for the Propagation of the Faith, the Society of St. Peter Apostle, the Missionary Union of Priests and Religious, and ​the ​Missionary Childhood Association​. The principle aim of the Pontifical Mission Societies, which are international in scope and orientation, is "the promotion of a universal missionary spirit in the hearts of the People of God."

In the archdiocese, the Mission Office oversees the efforts related to the societies, including the Society for the Propagation of the Faith, as one of the four Pontifical Mission Societies. It is broadly supported by the faithful of the archdiocese. Under the direction of the Congregation for the Evangelization of Peoples (in Rome) and the bishops, the Society for the Propagation of the Faith seeks to foster an ever-deeper spirit of universal mission, inform Catholics of the life and needs of the Catholic Church in the missions, and encourage prayer and financial help for those mission churches.

Through the offerings from Catholics worldwide, the Society for the Propagation of the Faith provides ongoing support for the pastoral and evangelization programs of the Catholic Church in Africa, Asia, the Pacific Islands, and remote regions of Latin America. This includes aid for the education and support of seminarians, religious novices, and lay catechists; for the work of religious communities in education, health care, and social services; for communication and transportation needs; and for disaster and emergency relief when necessary.​​​
