Theology is part of a conversation

Marilynne Robinson, author of Gilead, on the importance of doing theology, and of not thinking you're the only one or the first one to do it:

Theology always needs to be written again. But, I think that the best theology is written with an awareness of what has been said before. To affirm, to elaborate, or reject. 

—Marilynne Robinson, "Interview with Marilynne Robinson," from the Center of Theological Inquiry, 1:12-1:24.
