“Of course there will be gay weddings, but after lawsuits...”
No there won’t. The Church has withstood this type of intimidation for over 2000 years and will close and deconsecrate the church, essentially abandon it, before joining two sodomites in holy matrimony.
If the church wants to keep its tax free status, or perform public weddings, baptisms, counseling or adoptions, they will kowtow to the PTB, or be destroyed financially. It is another step to the destruction of the family, and the church will need to drop its tax free status to be free to choose. Not many will do that. There was a photographer in San Diego, that refused to be hired to take wedding pictures, but referred the woman woman couple to another. She was sued, and lost the case. The California supreme court upheld the verdict. Similar things happen in Canada all the time, you can even lose your tax free status, and be criminally liable for preaching against sodomy, same sex marriage, and warning people about the dangers of Islam. Coming soon here, their weapon, the courts.
