Every year, Mitt Romney and his family spend a week at his estate on picturesque Lake Winnipesaukee. They go boating, play games — and attend church, an expression of the faith that's fundamentally shaped the Republican presidential candidate.

Romney, the first Mormon to clinch the presidential nomination of a major party, attended services Sunday with his wife, Ann, five sons, five daughters-in-law and 18 grandchildren. They made up nearly a third of the congregation that gathered inside the small, nondescript building that houses this tiny resort town's branch of the Church of Jesus Christ of Latter-Day Saints.

The Romney clan has attended the church in Wolfeboro many times before — only now the family patriarch carries the distinction of being President Barack Obama's Republican challenger.

Not that church leaders or worshippers mentioned the new reality as, one by one, they stood at a podium to offer testimony, a custom in Mormon churches on the first Sunday of every month. Among those testifying: one of the many Romney grandchildren.
