Bristol CU have issued a statement in which they confirm they will be extending speaking invitations to both men and women. It makes the point the whole issue has emerged out of an ongoing dialogue about how to accommodate people of varying theological perspectives. For an excellent description of what has happened and the significance of it for both Bristol and UCCF see this post from Danny Webster.
What has been seen here is a playing out of wider issues within the church, how to accommodate difference, particularly difference which emerges from different interpretations of the bible and feeds into wider debates on equality. I wish them all the best as they continue to do this difficult task.
