Camillians
The Camillians or (Clerks Regular) Ministers to the Sick are a Roman Catholic religious order of the type of Regular Clerks, founded by Saint Camillus de Lellis. A red cross was chosen by Camillus as the distinguishing badge for the members of the Order to wear upon their black cassocks. The founder taught his volunteers that the "hospital was a house of God, a garden where the voices of the sick were music from heaven".
