Did all denominations come from the Catholic faith? I have been asked this question and I did not have an answer.
In a round about way, you could say that all protestant denominations came from the Catholic faith. The process began in the 16th century with a movement that was initially intended to reform the beliefs and practices of the Catholic Church but resulted in the breakaway we know as the Protestant Reformation.
Subsequent divisions within the protestant movement, usually over doctrinal differences, have resulted in the formation of numerous denominations and other less formally defined groups, a process that continues to this day.
