The first same-sex marriages in the UK took place in 2014. A decade later, many of us Christians feel we are still playing catchup: we are trying to get our heads around same-sex sexuality and how to hold on to our Biblical conviction that marriage is the lifelong union of a man and a woman while simultaneously loving well those who are attracted to people of the same sex. We are wrestling with how both to love God and love our neighbour in relation to same-sex sexuality.
But while Christians have been playing catch-up, wider society has been continuing to develop its sexual ethic. Same-sex relationships aren’t really a point of debate for most people in modern Western society. In fact, to many, it seems obvious that two people of the same sex should be able to marry.
Today, a new frontier is emerging in sexual ethics, one that is likely to grow significantly in acceptance and practice in coming years, and one that Christians ought to start thinking about now. That new frontier is polyamory. We need to start wrestling with how both to love God and love our neighbour in relation to polyamory.
