They are children being brought up in a family with Christian values Joe and that is a very different thing. Just about every religion has a ceremony of rites of passage. There is a genuine reason for that.

You can say a child is blonde, has blue eyes or is American by birth but you cannot ascribe something suggestive such as religion and make mental leaps.

Children are by any value innocent. There rests the case M'Lud.

If by choice in the future retain their faith then you have another card carrying member and I hope it is a comfort for them rather than fuck their brains, but a child is a child and dressing them as adults doesn't alter it one jot. Your Bible explains it better than I can.
