(previews start on Wednesday; opens on May 20) Robert Askins's "Hand to God" is playing uptown; his latest comedy gets handsy downtown, too. Justin Bartha and Elizabeth Reaser play a married couple who adopt Christian Domestic Discipline. Nicole Lowrance, Talene Monahon and Lucas Near-Verbrugghe are co-stars, and Alex Timbers directs the brand-spanking-new show.
