I spent about 15 years, starting at age 12, as a titular Mormon. My mother was converted from Methodism by a couple of nice young men in black suits and white shirts who introduced themselves as "Elder" somethingorother. She dragged my brother and me along. When I was 27 my mother urged the church to excommunicate me. They took her up on it. Everyone is happier as a result.
My mother died 20 years ago. As St. Peter reviewed her resume', he exclaimed, "You advocated that your own son be denied the company of God and JC because he smokes cannabis? Wow! Come right in!" Abraham was ready to stab his son at the behest of God, remember.
Mormons encourage members to construct their genealogy. That's cool. Genealogy is fascinating.
Part of the reason the Mormon Church promotes it is to set the stage to baptize our ancestors by proxy, because if they were not baptized into the Church of Jesus Christ of Latter Day Saints during their lives, and assuming they had lived lives righteous enough that they didn't go straight to Hell, they've been sitting in a waiting room right outside of heaven since their deaths. "I know you were a good person, but you gotta wait until your great-great-great grandnephew gets you placed in the family tree and then goes and gets wet in your name."
Lately, some progeny of holocaust victims have been taking offense at the practice. Some of their cousins have converted to Mormonism and are undertaking this rather weird work of baptizing-by-proxy their Jewish grandmother who died at Auschwitz.
Really? Do Mormons really believe that God is holding up the papers of people who were starved, beaten, experimented on, gassed and cooked by the Nazis?
Of course that's only a half-step beyond the weirdness professed by most of those who call themselves Christians. Romney, Gingrich and Santorum all advocate rather bizarre policies based on their interpretation of what they call their "faith."
