What if the Celtic church survived and the protestant reformation never happened
The Celtic church was a branch of Christianity created by the welsh and Irish, but was shortly incorporated into general Catholicism. In this timeline it survives due to the papacy focusing all of their resources on converting pagans in continental Europe and fighting the Byzantines. Martin Luther moves to denmark and converts to Celtic Christianity instead of trying to reform the Papacy.
