All Foods Clean

And he called the people to him again and said to them, “Hear me, all of you, and understand: There is nothing outside a person that by going into him can defile him, but the things that come out of a person are what defile him.” And when he had entered the house and left the people, his disciples asked him about the parable. And he said to them, “Then are you also without understanding? Do you not see that whatever goes into a person from outside cannot defile him, since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.) And he said, “What comes out of a person is what defiles him. For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. All these evil things come from within, and they defile a person.
Mark 7:14–23

All Foods Clean
The Lord had set aside his holy people from the rest of the Gentile world. He gave them special clothes to wear, food to eat, and language to speak. He circumcised their baby boys. They were not to be like the rest of the world. Jesus fulfills these ceremonial laws. His people, washed in his blood, are set apart by his work on the cross. People everywhere are set aside in their baptisms as his people. They are marked with his cross (both upon their foreheads and their hearts) and with his Name (Father, Son, and Holy Spirit) to mark them as one redeemed by Christ the crucified. He gives us a new food. He gives us his very own body and blood to eat and to drink. That calls us out as his own. He gives us a new set of clothes to wear: the robe of righteousness. He gives us the Church's language to speak: the Liturgy and the Church's songs to sing: the Psalms and the Hymns. We are his own. He has made us new in him.
