Sorry is the Hardest Word
It might indeed be that we need to avoid rushing ahead with further such 'prophetic acts'. But the other side of that bargain would be, that those who regard them as mistakes go back to prayer. Not along the lines that they've prayed up till now, ("Please, Lord, show these liberal unbelievers they are wrong and bring them to repent,") but along the lines of "Lord, we are all mistaken. Show us where we all need to change our minds and learn your truth. Show us your way of keeping the church united, at the same time as including people we categorically disagree with. Better yet, help us to learn to value them, understand where they are coming from, and who knows? maybe even agree with them."
