Palmer’s chapter of the International Order of St. Luke (OSL) the Physician is an ecumenical Christian healing ministry and fellowship of men and women who believe healing is an essential part of the teaching of our Lord Jesus Christ. The work of the order is carried out through teaching and prayer. Members are committed to intercessory prayer – that is, praying for others. They serve on prayer teams, sponsor healing services, and lead workshops and missions.

OSL grew from the Fellowship of Saint Luke, begun in 1932 by the Rev. John Banks, an Episcopal priest, and his wife, Ethel Tulloch Banks. Today there are chapters all over North America and in many countries around the world. Chapters are interdenominational.
