Romans 14:3

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

And He also told this parable to some people who trusted in themselves that they were righteous, and viewed others with contempt:

Now accept the one who is weak in faith, but not for the purpose of passing judgment on opinions.

But you, why do you judge your brother? Or you again, why do you view your brother with contempt? For we will all stand before the judgment seat of God.

Therefore let us not judge one another anymore, but rather judge this—not to put a stumbling block or offense before a brother.

Therefore, no one is to judge you in food and drink, or in respect to a festival or a new moon or a Sabbath day—

But solid food is for the mature, who because of practice have their senses trained to discern both good and evil.
