ARLINGTON, Mass. — Three decades ago, Carolyn Caci, a recently divorced Mormon convert, joined a congregation here presided over by a young church leader named Mitt Romney. As the local bishop, Romney conducted annual interviews with all the members of his flock, and he used his time with the newcomer to express both his disapproval of divorce and to remind the middle-aged woman, who had begun dating again, about the church’s opposition to premarital sex.

“I got awfully mad,” said Caci, now 80. “I told him it was none of his business and he said it was.” Romney persisted, she said, and also warned her to avoid consorting with a group of devout but independent Mormon women who had eased her transition into the church. Caci said she reported her “run-in” with Romney to those women, who published a Mormon feminist journal titled Exponent II.
