You won't convert the Pharisees
When there is tension within the Body of Christ, in the local church, it is usually because the wheat do not have anything in common with the tares. This has nothing to do with doctrine, but with the fact that there are very two different spirits abiding within the church: that of the Pharisee's (the tares), and that of Jesus (the wheat). When we are called to "love everyone," that does not mean that we are to set up camp with some of them! Jesus did not hang with the Pharisees when He walked this earth. Jesus' love was not the mushy, gushy sort of love that we can confuse with real love. Jesus actually said that there was more hope for the whores and tax collectors than the religious leaders when it came to salvation! Jesus said to them, “Truly I say to you that the tax collectors and prostitutes will get into the kingdom of God before you." Matthew 21:31 Not exactly a way to win friends and influence people. So don't even bother trying to "win"
