I'm quite sure I understand the concept of Total Depravity, but I'm not sure it's viewed exactly the same in different doctrinal frameworks that support it. I've spent a lot of time among Lutherans, and while I'm sure they support Total Depravity, they usually rather talk about Original Sin. Is this because Total Depravity as a term originates in Calvinism?
I came upon a table comparing the Lutheran, Calvinist and Arminian ideas of Total Depravity, but I don't quite understand it. Can you explain the main differences in the three views to me?
