I've seen many books and articles that use the word God-talk. This seems, often, to be used as a friendlier alternative to theology, which comes from the Greek θεός (theos) for God, and λόγος (logos) for word, talk, discourse, etc., and therefore meaning something like God-talk. Some examples from a Google Books search are:
- The End of God-Talk: An African-American Humanist Theology, Anthony B. Pinn (OUP, 2012)
- Racism and God-talk: A Latino/a Perspective, Rubén Rosario Rodríguez (NYU Press, 2008)
- Doing girlfriend theology: God-talk with young women, Dori Grinenko Baker (Pilgrim Press, 2005)
- Sisters in the Wilderness: The Challenge of Womanist God Talk, Delores Williams (Orbis, 1993)
- Sexism and God-Talk: Toward a Feminist Theology, Rosemary Radford Ruether (Beacon Press, 1983)
It looks like this term is mainly being used by authors in feminist, womanist, and mujerista theology; African-American theology; LGBT and queer theology; and so forth.
I am curious about how this term originated and became popular, especially in relation to the communities just mentioned, and about what its connotations are, in contrast to "theology". (For example, I have a rough impression that "God-talk" covers any kind of talking about God in everyday life, as opposed to theology which is done in an academic or formal setting, but this is only an impression without evidence.)
