The National Association of Catholic Nurses, USA gives nurses of different backgrounds, but with the same Roman Catholic values, the opportunity to promote moral principles within the Catholic context in nursing and stimulate desire for professional development.

This approach to Roman Catholic doctrine focuses on

  • educational programs,
  • spiritual nourishment,
  • patient advocacy, and
  • integration of faith and health.

As we continue to share our faith and values with each other, and with other healthcare providers, we simultaneously reach outward to the larger Church and also our communities, as we offer support to those in need.

Donate to the only association exclusively dedicated to supporting, nourishing and strengthening Catholic Nurses in the USA.

Our Lady of the Immaculate Conception

The National Association of Catholic Nurses, U.S.A. traces our roots to 1909 when the first local Council of Catholic Nurses, the Guild of St. Radegonde for Nurses, formed in Boston, Massachusetts. In 1924, the International Catholic Guild of Nurses (ICGN) was founded in Milwaukee, Wisconsin under the spiritual direction of Fr. Edward J. Garesche, S.J.

In the early 1930’s, a few existing groups of Catholic nurses from the USA, along with nursing groups from several other countries, assembled in Lourdes, France, and found what is now known as the International Catholic Committee for Nurses and Medico-Social Assistants* (CICIAMS). This Private Association of the Christian Faithful promotes Christian and professional values in nursing care. It is recognized by the Ecclesiastical Authority, and has a close working relationship with the Holy See, through the Dicastery for Promoting Integral Human Development, along with all national and international Catholic organizations around the world.

The Holy Father, Pope Pius XI, in a letter, asked that there be local associations of Catholic Nurses where feasible, according to the needs of the respective diocese, under the guidance of the Bishop, and in due time be united to create the National Council. The late Pope Pius XII reiterated this request of his predecessor by saying, “The Catholic Nurse must carry on her professional activity in the light of the Church’s doctrines and Christian morality.”

After the formation of CICIAMS, the ICGN adopted a new constitution and bylaws of a “national character” and changed to the National Federation of Catholic Nurses with headquarters in Chicago, Illinois. At the request of Pope Pius XI Local Councils of Catholic nurses continue to form across the United States. The oldest are located in the Diocese of Youngstown, Albany and Chicago. Around 1942 the ICGN became known as the National Council of Catholic Nurses (NCCN).

The NCCN was suceeded by the National Catholic Nurses Association-USA (NACN-USA) in 1993 formed under the auspices of the Diocese of Joliet, Illinois, with the permission and spiritual advisement of the bishop at that time, Bishop Joseph L. Imesch. In October, 1994, the Association became a full voting member of CICIAMS, thus all NACN-USA members are also part of CICIAMS through the Association. Two years later, in October 1996, NACN-USA was approved by the U.S. Conference of Catholic Bishops for inclusion in the “Official Catholic Directory” under the Joliet Diocese. NACN-USA is registered as a non-profit 501c3 organization. Several local/regional councils remain as independent affiliates of NACN-USA and others are in formation.

1935 2nd International Congress of Catholic Nurses (now CICIAMS) held in Rome
Pope Pius XI address, “After describing the important work of the Nurse, her lofty vocation and the preparation so necessary for the successful execution of her mission to the sick, His Holiness Pope Pius XI told the assembly that it was the duty of every Catholic nurse to belong to Catholic associations of nurses and to promote them in every way possible (excerpt from G. Cardinal Pizzardo’s 1937 letter to bishops).

1937 Excerpt from the Address of Pope Pius XI to the 3rd International Congress of Catholic Nurses:
“…The exercise of the profession of nurse is surely one of those which offer the greatest possibility for the apostolate, but we must not forget that the nurse, in the exercise of her profession, has to employ all sorts of technical means, and lives in a materialistic atmosphere, exposed to the danger of a limited interior piety only, dissociated from the profession and exterior practices enjoined by the Church. Furthermore, modern theories seek to penetrate the minds of Catholic nurses and to make them become unconsciously strong agents for the propagation of eugenics and neo-malthusianism. It is necessary, then, to protect them by means of Catholic Action, which has for one of its duties to sustain and fortify them in their professional and Christian formation.”
(Reference p25 Conference Report – Excerpt from Pope Pius XI address).

1937 3rd International Congress of Catholic Nurses (now CICIAMS) held in London.

1938 G. Cardinal Pizzardo shared the report from the 3rd International Congress of Catholic Nurses (now CICIAMS) and wrote each bishop expressing His Holiness Pope Pius XI’s desire “that ways and means be found to emphasize the necessity of bringing all Catholic nurses within the influence of Catholic Association of Nurses” and requested “In accordance with this wish of the Holy Father, It is most desirable, Your Excellency, that the Catholic nurses of the United States be gathered into one national association under the direction of the respective Ordinaries of the Hierarchy.” …”In keeping with the wish manifested in the words of His Holiness, that the Archbishops and Bishops should organize local associations of Catholic nurses according to the needs of their respective diocese, which in due time, under the guidance of the Hierarchy, might be united to create a National Federation of Catholic Nurses.”
