its not the governments business to educate religious doctrine.
like sex education in the schools. It has no business there. It should (or should not if you feel that way) be taught at home.
Many schools teach it as literature.
Actually it's not the governments place to educate our children period. That was meant for the church and private enterprises to build and support. The system worked well for our nation till Washington politicians took it over in 1953 UNDER THE GOP's WATCH.
The Department of Education formerly the Department of Education, Health, and Welfare, was created under Ike's term as a Cabinet level position. The churches also did a fine job of running {oversite of} our hospitals as well as our welfare system till government took that over as well in one act. This IIRC is an elective course not a requirement. The founders were not against religious teachings in school but rather the prohibition of such. The Bible in our nations early years often doubled as the school primer in reading.
