From the first startling moments of Brad Sherrill’s glorious one-man performance of the Gospel of John, it’s clear how much he revels in its poetic power. The Atlanta-based Sherrill, a churchgoing Christian, brings energy, craft, and inspiration to this sometimes preachy, sometimes transcendentally beautiful part of the New Testament, which he delivers in its 20,000-word entirety. His subtle, sensitive, word-drunk performance in this Provision Theater Company production should please secular and religious audiences alike–though Jews may need a grain of salt to appreciate the literary power of a gospel that anti-Semites have used to reinforce the idea of inherited bloodguilt. –Jack Helbig a Through 2/25: Thu-Fri 8 PM, Sat 3 and 8 PM, Sun 2 PM, Royal George Theatre Center, 1641 N.
