At the heart of the Christian’s view of spiritual reality is a man who gave his life in sacrifice for people who did not believe in him, a man who died asking for forgiveness for the people who were killing him. Therefore, Christianity is an exclusive claim, but it is the most inclusive exclusive claim because it wants you to exclusively believe in this man who died for his enemies, and asks you to love and care for yours.
So, does the message that Jesus is the only way to God necessarily lead to intolerance? Christians can only become intolerant to the degree that they misunderstand the heart of the gospel — namely, the good news that Almighty God himself came to serve us and die for us, so we could be saved not because of our right beliefs and behavior, but by the gift of his unmerited grace. That message, rightly grasped, cannot lead to coercion or intolerance. The gospel has within it deep resources for humility and respect. It is up to Christians to prove this assertion with their lives.
