It's tempting to tag this tale of star-crossed love in a Catholic seminary "The Sermon on Brokeback Mount." But the characters have more than private/public conflict to deal with--theirs is a love triangle rounded out by God. This could've made for ultranarrow material, but the thoughtful script--developed by the two performers and director Lessa Bouchard--delves into the existential dilemmas underlying all faith. And the well-drawn Michael (Grant Stokes) and Jeff (Garrett Prejean) represent two common ways that devout but moderate Catholics of every sexual persuasion negotiate the dogma that draconian literalists take at face value. The play undeniably runs long, and despite some full frontal nudity, gets dry in patches. But committed, understated performances offer rewards for a patient audience. Opens Fri 9/1, 8 PM. Through 9/29: Fri-Sat 8 PM, Sun 4 PM, EP Theater, 1820 S. Halsted, 312-850-4299, $20.
