Romans 14:4

because it does not go into his heart, but into his stomach, and goes to the sewer?” (Thus He declared all foods clean.)

Do not slander one another, brothers. He who slanders a brother or judges his brother, slanders the law and judges the law; but if you judge the law, you are not a doer of the law but a judge of it.

There is only one Lawgiver and Judge, the One who is able to save and to destroy. But who are you who judge your neighbor?
