Question

What German monk believed that Christians had to live by faith alone and depend on the mercy of God?

Answer 1

I believe it would be more proper to ask this question in the HippoCampus Religion section @shadostrike13.

On answering your question, Martin Luther was a German monk who believed that Christians had to live by faith alone and depend on the mercy of God. Martin Luther elevated \(\textit{sola fide}\) quite to a high standard in the Reformation.

Peace.
