I'm not sure whether the theological/Christological views of John D. Caputo count as fideism in the sense in which that term attaches to, say, Tertullian, Pascal, Kierkegaard, or Karl Barth.
Whether he joins that august company or not, as the significance of his works comes to be sorted by time, I'm glad he recently came within my ken.
Caputo's works include:
AGAINST ETHICS (1993)
THE WEAKNESS OF GOD (2003)
And at essay length, "Temporal Transcendence," in TRANSCENDENCE AND BEYOND (2007).
The title of the anthology to which I've just referred reminds me a bit of Buzz Lightyear's expression, "To Infinity and Beyond." But that is probably unfair to them both.
One quote. Caputo is often quoted saying this, though I don't know the sourcing specifics for it.
"I am seeking to know what religion would look like, what form it would take, if it were wrested free from people who consider themselves authorities in matters in which we are all unlearned novices and perpetual beginners."
Another possible candidate for the title "fideist" is Graham Ward, author of Barth, Derrida, and the Language of Theology. But I'll leave him to another time.
