Religious education should be taught throughout primary and secondary school from the very earliest grades continuously through to graduation. Christianity should be the default religion, but parents should be allowed to choose any other religion they would like their children to study. At age 14, children should be allowed to choose which additional religion(s) to study, but they should still study the religion their parents chose for them. Regardless of which religion is studied, fundamental religious teachings should include a thorough study on the religion’s facts including logical coherence as well as its historical and scientific accuracy. It should be taught that religions are not merely a form of entertainment, but that all aspects of every religion should be tested for accuracy and truth, especially in the scientific sense. Simultaneously, students should be taught that neither religions or religious doctrines or statements cannot be correct for one group of people while simultaneously incorrect for another. Naturally, variations in style, form, custom, or any other aspect of how a religion is practiced can almost always be accepted as unobjectionable variety and diversity within the religion. If any provable contradictions are found within a religion, that religion should either be discarded outright (if it is a fundamental error within the religion) or at the very least the scientifically offending portions of the religion should be discarded or modified.
Parents should be encouraged to have their children study Christianity. Children who reach age 14 should be allowed to choose for themselves which additional religions (if any) to study, but Christianity should be encouraged. Christianity is the only religion that is logically coherent as well as historically and scientifically accurate.
To provide the most immediate secular benefit, emphasis should be given on religious teachings, whether they are from Christianity or from any other religion (as much as is possible within that religion), that relate to the existence of one loving and personal God, the reality of an afterlife, the existence of both Heaven and Hell, and the reality of each individual’s appointment with God to give an account of every evil word and deed spoken and committed throughout an individual’s lifetime.
One essential purpose of such teachings throughout primary school is to instill within each student an effective internal mechanism which would allow them to more effectively resist the temptation to do mischief, even when they think no one else is watching or that they will never be caught. Many religions from around the world can accomplish at least most of these goals; however, Christianity may be the most effective and comprehensive.
