Sorry, can’t agree with your definition.
It assumes there is one God. While I personally agree, there are and have been many religions with a different POV.
There are and have been religions with many gods, and religions with no gods.
I personally consider them false religions, but they’re false religions, not non-religions.
I also do not want my, or anybody else’s beliefs about religions, incorporated into our legal or constitutional system. Let all the religions, true and false, duke it out in the public square.
That’s because only one God has provided us a true religion.
Respecting any other religion disrespects His legitimate authority.
The American political doctrine of ‘freedom of religion’ was premised upon Christianity, with different religions being different denominations within Christianity, all originally premised upon Judaism, all directed back towards God on His Word.
In understanding religion, study how it is used in Scripture. The Old Testament rituals in the Tabernacle were religious and true and provided by God. On the contrary, the Puritans premised their religion upon Scriptural worship of God through faith in Christ, void of all Roman Ritual.
Islam lacks verity as it was synthesized some 6 centuries after the Resurrection and Ascension, without adequately addressing Jesus Christ.
