>And they were baptized after the age of consent?
I understand there are wide variations here, among different churches, and of course individual believers. Some have the more reasonable (IMO) belief that a person should choose his religion after the age of consent. Therefore, some will only accept a baptism after some age of consent. Others will accuse you of apostasy, even if you were baptised as a baby.
Some clarification of terminology is in order. If you change your religion, for example, from Muslim to Christian, you are a "convert". If you change the other way around, you are an "apostate". That is, if you talk with a Christian. If you talk with a Muslim, it may be the other way around.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
