How would you write a one-liner law against theism?

[Cecelia]

Church and State shall remain separated in such that the government shall not have any involvement in religion (including protecting religious definitions, no laws shall be passed solely based on religious doctrine nor to protect any religious institutes, or putting up religious monuments on public grounds, and excepting for court cases involving church officials and crimes committed by clergy including but not limited to child molestation and extortion) and the church shall not have any involvement in government (including endorsing candidates) save for the express paying of taxes.
