Ah. You want a sort of Christian Madrasah, then.
Ah, equating the Christian Faithful to Islamist Shariah Fundamentalists...
How original.
You know, that might be a good idea for missionaries in post-Islamic cultures. Offer Christian education using culturally-aware settings. After all, if Roman Christians could hijack Saturnalia, should we not view the traditions of other societies as ripe for pillage and re-purposing?
The madrasah, FWIW, shuts down cognitive processing by focusing on rote repetition of an incoherent "sacred" text in a foreign language. Christian education opens the mind by giving the scholar the tools for learning, for organizing, sorting, and working with information. Secular humanism offers a file drawer with one category, Miscellaneous.
Finally, give thought to the possibility that public education is incredibly successful at achieving its real purpose -- creating docile cannon fodder and factory hands to be used as resources by Caesar, and his minions, the banksters. Google John Taylor Gatto, and read his book The Underground History of American Education. Those who opt out, home school families, are raising millions of smart, personable, and competent children on their own dime. Kids who typically score in the top 20th percentile in academic and social metrics.
America has a bright future, since so many are repudiating the cult of Caesar, and its priestly caste.
