Mormon’s explain why baptizing the dead is okay.
The practice is rooted in the belief that certain sacred sacraments, such as baptism, are required to enter the kingdom of heaven and that a just God will give everyone who ever lived a fair opportunity to receive them, whether in this life or the next. Church members who perform temple baptisms for their deceased relatives are motivated by love and sincere concern for the welfare of all of God’s children. According to Church doctrine, a departed soul in the afterlife is completely free to accept or reject such a baptism — the offering is freely given and must be freely received. The Church has never claimed the power to force deceased persons to become Church members or Mormons, and it does not list them as such on its records. The notion of coerced conversion is utterly contrary to Church doctrine.
My favorite line: The Church has never claimed the power to force deceased persons to become Church members or Mormons, and it does not list them as such on its records.
Force deceased persons to….
You know, it really doesn’t matter what comes after those words. Game over.
