The Mormon church has claimed this in the best interest of the children. I disagree on every level with them since the Mormon church believes baptism is a saving ordinance and they are denying a saving ordinance from children:
1. They are making children choose between a saving ordinance and their parent
2. They are making children choose between their parent and the church
3. They are separating the child from their peers, while they are advancing the peers in the priesthood and the young womens, they are preventing these children from taking part in these rituals., including doing baptisms for the dead with their peers
4. They are setting these children up to be ridiculed and bullied by their peers because they are setting them apart, making them different by not allowing them to participate in giving talks in church, in praying, in advancing the same way their peers are
5. They are usurping the role of parent since it is the role of parent to determine what will and will not cause harmony or discord within the family and it isn't the role of the church to determine this
6. It is the role of parent to determine a religion for their children, it isn't the role of religion to determine what religion a child will or won't be raised in.
One more thing I must add. Many Mormons have been quoting their favorite apologists blog, Greg Trimble where he says that Jesus didn't accept everyone, implying that Jesus would reject the same people that Mormons reject. I agree with the premise that Jesus didn't accept everyone, I absolutely reject the premise that Jesus rejected gays, as there is NOTHING in any Biblical scripture to suggest such a thing.
I will agree with Greg Trimble that Jesus did reject some people. Jesus rejected people who took financial advantage of people by selling things at the temple, he rejected the church leaders who did not take care of the poor and did their alms in public. He rejected the leaders who were hypocrites.
When I stopped believing in all the tenets of the Mormon church, I started drinking coffee, tea and alcohol, since I no longer believed these things to be sinful. I also had these things in my home. My true believing Mormon family, however, believed me to be sinful and would not come into my home, even when my Mom died. My family traveled great distances for my Mom's funeral and spent a great deal of money to be here for her funeral. I offered my home as respite for them. Not a single family member would stay in my 'sinful' home to save money or share in our grief together. I was shunned because of my sins. Love the sinner, hate the sin, right? It is impossible to separate the two out.
If Mormon's truly believe this new policy will not shun children and parents, they are in error.
I wish people would think for themselves. If your first reaction to this new policy is one of revulsion, then your morals are telling you it is wrong. Why would you trust any person above your own ethics?
