Q. 1. I heard that there is a "Red Mass." (See Question & Answer # 1404.) But is true that there is also a "White Mass?"
A. 1. Yes, there is a "White Mass." According to Wikipedia,
"The tradition of the White Mass in the United States finds its origins in the development of the national Catholic Medical Association in the early 1930s. The White Mass, so named by the color worn by those in the healing profession of medicine, is held in recognition of the dedicated work of healthcare professionals and to ask Godís blessing upon patient, doctor, nurse, and caregiver. The Archdiocese of St. Louis celebrates a 'White Mass' every year for those involved in healthcare. The Mass is associated with St. Luke, the patron of physicians and surgeons, whose feast day is October 18. The Archdiocese of Atlanta also celebrates a White Mass honoring health care professionals, as does Creighton University. St. Patrick's Cathedral in Norwich, Connecticut held its twenty-fifth White Mass in 2015. The speaker at the brunch following the mass was Lt. Commander Seth Flagg M.D. of the U.S. Marine Corps Wounded Warrior Regiment."
"In Lewiston, Maine, the White Mass is held in February to coincide with the World Day of Prayer for the Sick, instituted by Pope John Paul II in 1992 as "a special time of prayer and sharing, ... and of reminding everyone to see in his sick brother or sister the face of Christ". It is celebrated on February 11, the Feast of Our Lady of Lourdes."
