It is clear the religious leaders have blurred the line when it comes to the separation between church and state. Leaders in both the Catholic Church and the Mormon Church were instrumental in championing the unconstitutional Prop 8 in California. A $1.4 million contribution to the Yes on 8 campaign came from the New Haven, Connecticut-based Knights of Columbus (of which all Catholic Bishops and priests are members), while an additional $200,000 came directly from the U.S. Conference of Catholic Bishops. In collusion with the Catholic Church, the Mormon Church (LDS) participated by providing money ($5 million), institutional support and dedicated volunteers to walk door-to-door. Presently, the Catholic Archdiocese of Minnesota plans to institute anti-gay marriage committees in every Catholic church in Minnesota and vows to do all in its power to see that an anti-gay marriage amendment is included in the Minnesota Constitution. In addition, right-wing Christian fundamentalist churches are working through the National Organization for Marriage and the Family Research Council in Minnesota on this legislation.
IRS rules clearly state that churches and religious organizations "must not devote a substantial part of their activities to attempting to influence legislation," and they "must not participate in, or intervene in, any political campaign on behalf of (or in opposition to) any candidate for public office."
Churches are no longer ministering, but are engaging directly in the political process. By virtue of this, their 501(c)(3) tax exempt status should be subject to Internal Revenue Service review, and then revoked.
