bleeding deacon
 n.— «Even in aftercare or AA, if this quality of rigidity continues, it can reach a point where patients are no longer viewed by their peers in recovery as a zealot for the program but as “bleeding deacons” who insist loudly that “my way is the only way to make the program.”» —by Vernon E. Johnson I’ll Quit Tomorrow: A Practical Guide to Alcoholism Treatment , 1990. (source: Double-Tongued Dictionary)
