Do you think including explicitly religious instruction in the new england primer was a good method of instruction? why or why not?

The New England Primer, called as The English Protestant Tutor during the 17th century, was the foundation of the schooling system in the century for the American colonies. While it is largely based in King James Bible, the Puritan views are evident even until today. I think it is good to introduce faith in the system however, if this become the very hurdle to learn, then it is bad.
