Just something to provide a different perspective:
Perhaps most of the vocal opposition to Mormonism is produced by those who sincerely feel like we are stealing something. From this perspective, we steal members (and their attendant money) away from ministers and congregations, but we also steal souls away from Christ or tradition or family.
I interviewed many years ago for a position of teacher at a Quaker school. The principal told me directly that he would have to defend my hiring to one board member who had “lost a daughter to the Mormons.” Money had nothing to do with that father’s emotion; he truly felt his daughter’s spiritual life was in danger.
Likewise, one of my missionary companions was a native Japanese elder. He was the oldest son of the oldest son of the town’s Buddhist priest – going back about 16 generations. When he joined the Church, his father performed a death ceremony for him – in Christian terms, letting go of a damned soul.
Finally, early converts didn’t join and stay in their home towns with their families. They joined and moved thousands of miles away to live among the saints. They said, in essence, “I would rather be with Joseph Smith and the Mormons than with you, my family.” I know that is consistent with statements in the New Testament, but it still is a brutal message to hear as a parent or sibling.
In each of these cases, these people who opposed the Church believed deeply that joining the Mormon Church was tantamount to abandoning family and friends and jumping into the flames of Hell. They felt that the Mormon Church stole their children’s eternal salvation/soul/destiny.
That underlying feeling of being robbed in one way or another can’t be ignored – and for those of us who are parents, it should be understood better. Even though we disagree strongly, we should fight the tendency to take offense and be much more charitable in our reaction to opposition – understanding how we would feel if we “lost a child” to something in which we didn’t believe and which we felt would harm her eternally.
