Go read this (via Tim - also read that - and David, so read that too).
I was recently asked to be more explicit about what Christians can do to go further in their faith; to not just talk about the why and the what, but the how. Yet when I have done this, eg in saying Christians should not shop at Tesco, I meet great resistance. People simply don't want to be told this. It is seen as a curious quirk of the Rector's, not realistic, and certainly not much to do with Christianity. Christianity, after all, is about becoming a better person, more spiritually centred - and, in many cases, a rather obsessive and Levitical attitude to sexual practices.
I really don't think that God cares half as much as we do about human sexuality, most especially now that procreation is separable from it. Of course, there are ways of becoming wicked through the pursuit of disordered sexuality, but such a risk is vastly overestimated. The wickedness that is casually acceptable in Western society through the systematic exploitation of the poor and vulnerable in this country and worldwide is of far more concern to the God of justice and compassion who was incarnated in Christ. How often does Jesus speak about sexuality? As much as a whole column of a standard Bible at most? Yet concern for the poor and criticism of the rich runs throughout his ministry, as it does throughout the Bible as a whole. It is simply not possible to be a faithful Christian and not be concerned about issues of economic justice - indeed, to be much more concerned about such questions than about questions of human sexuality about which so much fuss is presently being made. That is simply one more example of how our church community has been captured by worldly idolatries - the world is presently obsessed with sex, and the church falls in with that emphasis. No wonder the church is seen as being irrelevant and out of touch. If this is all the Christianity in general, and the Church of England in particular, is capable of being, then it deserves a fate on the scrapheap of history.
