I have a question for Christians, especially Anglicans: Can homosexuality be reconciled with scriptural teachings?
OneHumanFamily, I believe it can, but I don't believe it changes the position on teaching about marriage being between 1 man/1 woman (any more than the church would accept polygamy, marriage between adult/minors, marriage between close family members, marriage with an animal etc.. or condone ANY sexual activity outside of a marriage).
If by being 'reconciled' you mean the interpretation of scripture will do an about face, I do not believe this is possible. To understand why, please indulge me in setting up some context...
I'm no theologian, but from my understanding, Christianity is based on the teachings of Christ (New Testament). Christians believe that there is a God (three in one - Father, Son and Holy Spirit) who created the world, everything in it and loves his creation and humans in particular. They were designed to be in perfect relationship with him, but he didn't create humans to be robots but have free will, and thus are subject to temptation by another spiritual influence in the world (known as 'The Devil'). Christianity's spiritual understanding is that these opposing forces (God - who is good and Devil - who is not) are at work in all our lives. God has our best interests at heart, the Devil is interested in destroying these.
Jesus said that he has two 'ground rules'' - Love the Lord Your God with all your heart and love your neighbour as yourself. All previous teachings (Old Testament) can be 'summed up'in these. Basically he says you're free to do whatever you want, as long as these principles are followed. Christianity is not about following a random/restrictive set of rules to try to earn favour with a disinterested deity, but engaging in a daily relationship with a creator God and living your own life in a way which honours this. Effectively, it comes down to the fact that if you're in a relationship with someone you love/respect, you will try to make choices and act in ways that would please that person (and they do they same for you) - ideal world. Christianity is about trying to live in a way that pleases God because you love him ('Love' in the sense of agape rather than eros or philia.
Clearly, this doesn't actually happen without failing (sometimes alot, sometimes a little). The position of the entire bible is that "'All have sinned and fall short of the glory of God" and that the only way now to be in relationship with God is to believe and say that Jesus was God's son sent to pay the price for that sin (by dying) but by then rising to life again, accepting that his doing this means you will be forgiven your sins.
So based on this fundamental truth of what Christianity actually is, homosexuality may well be considered a sin, but so are a lot of other 'human' characteristics that people are born with (from 'little things' like greed/arrogance/lying/jealousy etc.. to 'big things' like murder, abuse, theft etc.. Different people have different opinions on what is 'worst'').
I think the church has made a lot of mistakes in giving messages that heterosexual people are somehow 'better'' (or even less 'sinful') than homosexual people. They have certainly given wrong messages that being homosexual makes you unacceptable, or worse that God 'hates'you. This wrong and certainly something the church should repent of. After all, to God EVERYONE is sinful in some way and needs to be reconciled in relationship with him. There are obviously some sins which have more impact and worse consequences than others, but nonetheless God doesn't condone any sinful behaviour (and Jesus urges individuals to repent too - which means turn your back (sometimes over and over and for the rest of your life) on sinful attitudes/behaviours.
So homosexuality can easily be reconciled with scriptural teachings, on the same basis as any other 'sin'. But the issue is usually that calling it such is what is seen as wrong (in the same way humanity justifies/accepts a whole lot of other 'natural' inclinations with which we've been born).
If the church believes homosexuality is sinful, it would be hypocritical to then come out (no pun intended) in support of gay marriage. So when the Church makes a stand on marriage not being for homosexual partners, people are effectively complaining they are sticking to their sincere beliefs and are NOT being hypocritical.
However, one of the most damning criticisms of the church and Christians is hypocrisy (rightly so!). So, they are (ironically) 'damned if they do and damned if they don't'.
Not sure this answers your original question or not, but hope it explains some of my thoughts on why I don't believe the Church can change its stance without compromising/denying its fundamental beliefs.
