I'm finishing up in the MDiv program at Duke and the NT professors associated with the Divinity School (Joel Marcus, Doug Campbell, Richard Hays, Kavin Rowe, Susan Eastman) are confessing Christians. Some are more reserved about saying what they think on matters of faith, others are quite upfront about it. They aren't evangelicals per se, but if you're coming from an evangelical background it won't hurt you, as I've met people who've come from more evangelical/conservative seminaries that are in the PhD/ThD program.
