Hi @Adaml108 thank you for the question, I think this is a challenging one for many of us and really important to have a think about. I haven’t had to face the dilemma that you put forward yet, but I know it’s a struggle to come to a decision that fills me with peace.
I call it a dilemma, because I feel the main issues are that if a Christian takes the stance that homosexual marriage is not God‘s best plan for us, or if we feel the Bible is clear about not remarrying unless a spouse has died, then it feels like a choice between the Bible or our friends. I think the clinch on our conscience comes because if we attend a wedding, we could be seen as condoning the choice but if we stay away, we could be seen as judgemental.
My overwhelming conviction here is that if we are made in the image of God, our primary role is to love the person. How our demonstration of love looks may differ from person to person, but primarily, I believe our response should not convey a suggestion of the opposite.
I always think it’s a helpful thing to see how Jesus modelled this. Firstly, he was the Holy God who stepped into our world of sin. This was the first demonstration of stepping into something against who he is. When he was in flesh, he dined with tax collectors and prostitutes and anyone whom the culture labelled as sinful or unworthy. This helps me see that in these dilemmas, we are trying to convey the gospel into a different culture in our modern day. Paul, a very highly regarded Pharisee shunned anyone who did not meet his standards, until Jesus changed his heart. He spent the rest of his life stepping into the gentile world to show God’s love.
So as we approach our culture which says everything is permissible, my personal feeling would be to step into those places, accept those wedding invitations and spend time with your friends because that is how you can demonstrate the gospel message and God’s unconditional love. Whether you accept the invitation with a chat about how you feel Biblically is something you might consider too. If you are invited to such a wedding, maybe ask God to open conversations with the people in question, but always make a choice that tells them you value and love them as individuals. I think if we reject invitations, we risk closing the door to those friendships and therefore, conversations about Jesus.
Like I said, I’ve not had to face this myself yet so I’d be interested to hear from others who have.
