Outside the spotlight, Mr. Romney can be demonstrative about his faith: belting out hymns (“What a Friend We Have in Jesus”) while horseback riding, fasting on designated days and finding a Mormon congregation to slip into on Sundays, no matter where he is.
He prays for divine guidance on business decisions and political races, say those who have joined him. Sometimes on the campaign trail, Mr. and Mrs. Romney retreat to a quiet corner, bow their heads, clasp hands and share a brief prayer, said Representative Jason Chaffetz, a Utah Republican who has traveled with them.
Clayton M. Christensen, a business professor at Harvard and a friend from church, said the question that drove the Sunday school classes — how to apply Mormon gospel in the wider world — also drives Mr. Romney’s life. “He just needs to know what God wants him to do and how he can get it done,” Mr. Christensen said.
