Eleven years ago, two young men in white shirts and black ties knocked on Arcadia Scheel's apartment door. They were missionaries from The Church of Jesus Christ of Latter-day Saints, commonly known as Mormons.
Scheel, who invited them in, had drifted from Catholicism and was studying the Bible for answers. She recalls being impressed by the Mormon practice of tithing, or giving 10 percent of one's income to one's church.
