In this comedy about megachurch Protestantism, a fallen pastor is eulogized by two underlings while other congregants tease the audience with confessional lines like "Who among us hasn't gone online and sold your wife's titty milk?" There are some nice touches with the music ("Awesome God"), jargon ("Praise God" and "Hallelujah" are uttered often), and homophobia; there's even an anti-Christian lurking in the parking lot who proclaims that "literalists are literally retarded." Director Sue Gillan gets charismatic performances from writer-performers Beau Golwitzer and Brian Wilson, playing multiple roles, but by the end the material doesn't feel grounded enough in churchgoing experience to work as satire. Embodying a nebulous, fantastical Christianity, Testify can have little relevance for anyone but a quick-to-snicker liberal. --Ryan Hubbard a Through 4/29: Sun 8 PM, Annoyance Theatre, 4840 N.
