is this statement true if not tell me what really happened Monks and nuns, serving as missionaries, helped spread Christianity throughout Europe

The answer is true, but to a certain extent.

Explanation:

Monks and nuns helped out by playing many roles. The provided shelter, taught others how to read and how to write. They prepared medicine, sewed clothes, and overall helped others in times of need. But they did believe in Christianity and took many vows and spent most of their time praying along with meditating.
