Here is a quote from an article posted on a PCA website.
“As Reformed people, we tend to be dismissive of the charismatic movement,” Keller said. He pointed out that there’s a lot of “unfortunate and bad theology there,” including the “prosperity gospel,” which is often integrated into charismatic teaching. But Keller points out that Pentecostalism is the most vital, fastest growing, and most multiracial, multiethnic movement in the world. It is, he said, now bigger than the rest of Protestantism combined. And we [need to] know how in a nonpaternalistic way reach out and season that movement and help. Ecumenical relationships are important, Keller believes, and that is a weak spot for PCA. “That’s one we’ve got to figure out,” he said.
