I think that Reid is a Birth Mormon.
Nope, Reid's a Mormon convert who the Lds church has welcomed with such open arms that they readily made him into an elders quorum president, a high councilor, and Sunday School superintendent!
Reid, who has served as an elders quorum president, high councilor and Sunday school superintendent, converted to Mormonism while attending Utah State University in 1960. He subsequently converted his wife Landra from Judaism to the Mormon faith and has raised his family in the church.
