Jesus is the Truth and the head of His Church. To be out of doctrinal communion with the Church means separation from the Body of Christ. This group has already left the Church materially, if not formally.
Asked what Jesus Christ would make of the controversy, Father Kennedy replied: "Well, Jesus always stood with the poor, the broken and the oppressed. Jesus was not a Christian. He was a Jew. And he certainly wasn't a Catholic and he didn't start the Catholic Church. He didn't start any church.
Fr. Kennedy appears to be a heretic. He certainly denies the obvious in Scripture. Perhaps he doesn't listen when his ladies proclaim the Gospel. Perhaps he just skips certain readings.
