Which is why we are focusing on "home churches" - getting people used to meeting in homes instead of churches - prep. for coming persecution.
South Vietnamese pastors had thier congregations read "Tortured for Christ" by R. Wurmbrandt (founder of VOM) in preparation of takeover by the communists (Jane Fonda and Ted Kennedy's Red friends).
Home churches are a great idea, but to work they have to be strictly under the radar: no paid staff, no insurance, no property or trusts, nothing that could create a paper trail. The pastor would need to be a tentmaking pastor, which is a demanding way of life.
Perhaps a FReeper with more legal acumen than me could speak to the possiblity of the hosting homeowner being named a party in a civil rights lawsuit. To the point: could you be financially or otherwise liable for hosting a home church that refuses to marry homosexuals? My gut says yes.
