(Charlotte Observer) For the second time during the presidential campaign, a group of African-American ministers in North Carolina has criticized Franklin Graham for challenging the spiritual beliefs of President Barack Obama, accusing the evangelist Monday of promoting a narrow form of Christianity that supports a politically conservative point of view.

Meeting in Charlotte, the group read an open letter to Graham that comes in response to a series of full-page ads that bear a photograph of his father, Billy Graham, and ask voters to elect candidates who support “biblical principles.”

In comments to The Charlotte Observer last week, Graham said his 93-year-old father supported the message, which endorses candidates who support the nation of Israel, “the sanctity of life” and “the biblical definition of marriage.”

Franklin Graham went on to say that Obama’s support for gay marriage and abortion rights challenges “God’s standard” and says “it’s OK for people to sin.”
