“I am a professional Christian theologian/pastor-type connected to a mainline denomination. My ears always perk up when someone is claiming to speak for God, completely sure of “God’s will.”
Parents sometimes (often) do not know when it is time to cease trying to control adult children. And these children need to decide if they are willing to continue to be controlled by their elders, period.
And if God’s opinion, blessing or not, is truly important to anyone involved here, it is important to remember that God loves a sinner and understands the actions and motivations of this kind of “sin,” ESPECIALLY if it is the choice of a person of faith, one who is routinely in conversation with God. People need to do what will make themselves happy as long as they can live with their OWN decisions and THEIR understanding of God’s requirements of them.
As a parent of adult children, I can relate to the desires of “well-intentioned” parents and grandparents. But they need to remember and trust that, if they trained up their children well in the first place, they have no cause to worry how they will turn out. Having once stated their position quite clearly, perhaps the relatives should keep their voices out of their children’s business until they’re asked for their advice. Then they need to remember that children don’t have to follow that advice.”
