"There are two positions Vines’ book hinges on: 1, that celibacy has never been forced on Christians but instead has always been a choice, seen as a 'gift' that some have but that most do not, and, 2, that orientation cannot be changed. This second point is helped by the fact that Exodus International, the last major organization promising that orientation could be changed, closed its doors while Vines was writing his book — with the closing of Exodus and the thorough debunking of Mark Regnerus’ problematic research there is no longer any institutional level of support for the idea that orientation can be changed.  While many among the oldest generations of conservative Americans will not accept this in their lifetime, younger generations are already living in a world where the status quo regarding orientation is that it cannot be altered. Thus, the checkmate – if you believe orientation cannot be changed and you are also persuaded by Vines that celibacy has never been forced on Christians, it follows that there must be a Christian expression of sexuality for gay people. There must be and, according to Vines, there is: covenantal marriage."
