Based on what you understand from McGrath, would you argue that Luther or Augustine was a bigger influence on Calvin? Why?

Please limit your answer from 200-250 words.

Please write as an international student and don’t write as a Christian because Im not just write your response as if u don’t understand that much about religions and please make it simple as much as u can. It is also a text box submission and please don’t forget to make it simple. Without using other sources.

Thank you.
