There is one lawgiver, who is able to save and to destroy: who art thou that judgest another?
There is only one lawgiver and judge, he who is able to save and to destroy. But who are you to judge your neighbor?
God alone, who gave the law, is the Judge. He alone has the power to save or to destroy. So what right do you have to judge your neighbor?
