In an interview this week with the Christian Broadcasting Network, Gov. Sarah Palin of Alaska, the Republican vice-presidential candidate, was asked to “clear up exactly what you believe in” about her religious faith, including her involvement with Pentecostalism.

Ms. Palin responded by speaking generally, but extensively, about how she counts on God for strength, guidance and wisdom. “My faith has always been pretty personal,” she said. But she did not talk more specifically about her church affiliation or her beliefs.

Ms. Palin’s faith has come under scrutiny after two videos taken in her former church surfaced on YouTube and became immediate sensations. The first showed a visiting preacher from Kenya praying fervently over Ms. Palin in a gravelly voice and asking God to favor her campaign for governor and protect her from “every form of witchcraft.”

The second showed Ms. Palin at an event in June praising the African preacher’s prayer as “awesome” and “very, very powerful.” She is also seen nodding as her former pastor from Wasilla prays over her and declares that Alaska is “one of the refuge states in the Last Days,” a piece of prophecy popular in some prayer networks that predicts that as the “end times” approach, people will flock to Alaska for its abundant open space and natural resources.
