So how do we keep Sunday School from teaching "proof texting" and "idolizing the bible"? We could start out teaching our toddlers and preschoolers about the loving deity Jesus points to, and teach our elementary children that the bible is a book of stories about the people who worshipped a god named "YHWH", and teach our youth about historical and source criticism. Then we could teach and model the type of life that we believe the teachings of Jesus (and I mean the historical Jesus who taught the god of Love) calls us to.
While carefully choosing or writing curriculum resources is probably key, there is also a need to educate our teachers how to teach and model the Way Jesus taught and lived.
