The Harrisburg Diocesan Guild of the Catholic Medical Association is a physician-led professional organization dedicated to advancing healthcare through the lens of Catholic faith and moral principles. Based in Harrisburg, PA, the Guild serves as a chartered chapter of the national Catholic Medical Association, bringing together healthcare professionals committed to upholding Catholic teachings in medical practice and ethics. The organization focuses on several key service areas: informing healthcare professionals about Catholic medical ethics, organizing educational programs and professional development opportunities, and inspiring members to integrate faith principles into their clinical work. The Guild actively supports Catholic hospitals in applying moral principles to medical practice and facilitates collaboration among Catholic physicians and healthcare workers. Through events like the annual White Mass—a tradition dating back to the 1930s that celebrates the healing profession under the patronage of St. Luke—the organization gathers medical professionals to seek God's blessing upon patients, doctors, nurses, and caregivers. The Guild also hosts specialized programs such as Lenten mornings of reflection that bring together physicians, healthcare workers, medical students, and legal professionals for spiritual and professional growth. By maintaining steadfast fidelity to the teachings of the Catholic Church, the Harrisburg Diocesan Guild enables Catholic healthcare professionals to deepen their mutual understanding, work collaboratively with stronger support systems, and communicate Catholic medical ethics effectively to both the medical profession and the broader community. The organization operates under the Diocese of Harrisburg and conducts all activities in accordance with the teaching authority of the Catholic Church's magisterium.
