Personally I am not assured of necessity of teaching in school any one religion. Faith - is that to what a person should address himself making a deliberate choice. And teaching at school more likely will cause purely a conventional attitude to the Bible and religions, as to any other subject: has learnt, has answered, and has forgotten… Besides, now practically there are no places where there would live only one religion adherents. Probably, the survey course of world religions would be appropriate to help to understand subtleties and to make a choice.
