It appears after reading the Supreme Court Arguments that the Supreme Court will rule in favor of homosexual marriage at the end of next month. Justice Kennedy, the swing vote on the court, compared the recent cases dealing with homosexuality (Bowers, Lawrence, and Obergefell) to the Civil Rights cases (Plessy, Brown, and Loving). This would be an expected comparison when dealing with the lawyer defending the state bans on homosexual marriage, but Kennedy compared these cases during a discussion with the lawyer opposing the bans in Michigan, Ohio, Kentucky, and Tennessee.
This begs the question, what will Christians do when the Supreme Court elevates homosexual marriage to the status of heterosexual marriage? Once the Supreme Court does this it is likely to declare that any institution that refuses to accept homosexual marriage will not be eligible for non-profit status or government funding, as it did following Loving. Thus churches would face a decision, lose many of their charities and much of their organization or retain these institutions but cave and ignore what the Bible says. I predict we shall see some of both. Most likely this decision will result in the eventual closer of Hospitals, Adoption Agencies, Colleges, and other Christian organizations that rely on their non-profit status and their government funding. Also since the Government has taken over the student loan industry, students who take out student loans will not be able to attend Christian College. Christian Colleges that do survive will eventually face a battle to protect their accreditation.
Already in many conservative evangelical denomination there is mounting pressure with in the Church to accept homosexual marriage. For example at the Nazarene Church's last Church wide meeting in 2013, a large group of supposedly homosexual Nazarenes pushed for an amendment to allow acceptance of homosexuality within the Church, although in 2013 this amendment failed, the push to remake the Church in the image of man is growing.
