1 Cor 10:25
Eat whatever is sold in a meat market, making no inquiry because of your conscience, 26 for “to Jehovah* belong the earth and everything in it.” 27 If an unbeliever invites you and you want to go, eat whatever is set before you, making no inquiry on account of your conscience. 28 But if anyone says to you, “This is something offered in sacrifice,” do not eat because of the one who told you and because of conscience. 29 I do not mean your own conscience, but that of the other person. For why should my freedom be judged by another person’s conscience? 30 If I am partaking with thanks, why am I to be spoken of abusively over that for which I give thanks?
Mark 7:15
Nothing from outside a man that enters into him can defile him; but the things that come out of a man are the things that defile him.” 16* ——17 Now when he had entered a house away from the crowd, his disciples began to question him about the illustration. 18 So he said to them: “Are you also without understanding like them? Are you not aware that nothing from outside that enters into a man can defile him, 19 since it enters, not into his heart, but into his stomach, and it passes out into the sewer?” Thus he declared all foods clean.
