If the Church feels that 18 is an appropriate age for a child who lives in a sinful environment (homosexual couple) then why do they have any kids get baptized at 8? Is 8 not old enough? If it isn't old enough, then why don't we make every kid wait until 18? Why do we baptize children where one parent is not in the church and drinks and smokes?
If the reason is that we don't want kids to make a covenant that they can't keep because of their home environment, why do we baptize kids who have a parent who drinks or smokes? Isn't that kid just as likely to break their covenant? What about a kid who has parents who fornicated and their relationship is based on that fornication?
Why not wait until 18 to have EVERY kid baptized?
My kids are twelve, and they like to go to Church and participate in Church activities, but even though they want to be baptized, I have objected with reasoned specific concerns about the compliance the Church requires even of children who are unfairly caught in doctrinal cross currents they really can't be expected to independently evaluate and make covenants to comply with. Fortunately, the ward has respected that line of distinction.
Go ahead, send your kids to Church and be nice to the people who welcome them, and keep a lid on the controversy. They don't need to be baptized if you have that kind of concern.
I merely stated to the leaders that I believed some questions in the bishop's instruction manual required more specific beliefs than faith in Christ, and were inappropriate for children to be required to make any promise about.
