But Sproul addressed only a very narrow topic: not attending the ceremony itself (which, by the way, obviously precludes acting as a participant in some capacity). He left for another day the issue of relating afterwards to the "happy" couple, as I must do during occasional family gatherings with my nephew and his "husband." They both know very well my stance biblically, and it is not generally a topic for discussion at these large social events, although I am praying for them and for opportunities to dialogue. Indeed, recently I've been considering approaching them just for such a dialogue and wondering what the Holy Spirit is planning.
Meanwhile, I remain polite.
I think you are taking the right approach.
May God bless you as you continue to pray for them and witness to them.
Be careful and sure that you don’t allow your own heart to be compromised.
