Security video from St. Coleman Church on Pompano Beach shows a man tackling a deacon during a Saturday evening mass.
Several other churchgoers ran to help as the man wrestled with the deacon on the floor.
28-year-old Thomas Eisel was arrested on charges of battery and disturbing the peace.
A Broward County judge ordered Eisel held without bond for violating his probation in a Volusia County case.
It is unclear why Eisel attacked the deacon.
The Archdiocese of Miami told WSVN the deacon suffered some bruises but is otherwise OK.
