Words and music are the stock-in-trade at most Christian festivals, but the Wild Goose Festival is adding another component: the visual arts.

This year’s progressive Christian smorgasbord of culture, justice and spiritual exchange June 26-29 in Hot Springs, N.C., near Asheville, will feature plenty of speakers. Keynoters include newsmakers such as the Rev. William Barber, leader of the state’s Moral Mondays campaign; Jim Wallis, poverty activist and founder of Sojourners magazine; and Frank Schaefer, the United Methodist minister who was defrocked in December for performing his son’s same-sex wedding.
