What is the point of that question? They are both important figures in God's creation. That's all I need to know. I wouldn't dare to pretend to have Universal Knowledge, to determine those things. As a matter of fact, man's(Eve's) first sin was to want to play the role of God. I see that a lot lately. May God deliver me.
The point of the question, is that according to Catholic theology, Mary was born sinless. Moses was a sinner. So which is greater? Do Catholics worship Moses?
So, who is greater, Moses or Mary.
