Therefore do not let anyone condemn you in matters of food and drink or of observing festivals, new moons, or sabbaths. These are only a shadow of what is to come, but the substance belongs to Christ. Do not let anyone disqualify you, insisting on self-abasement and worship of angels, dwelling on visions, puffed up without cause by a human way of thinking, and not holding fast to the head, from whom the whole body, nourished and held together by its ligaments and sinews, grows with a growth that is from God. If with Christ you died to the elemental spirits of the universe, why do you live as if you still belonged to the world? Why do you submit to regulations, “Do not handle, Do not taste, Do not touch”? All these regulations refer to things that perish with use; they are simply human commands and teachings. These have indeed an appearance of wisdom in promoting self-imposed piety, humility, and severe treatment of the body, but they are of no value in checking self-indulgence. (Colossians 2:16-23, NRSV)
Jesus did not come to abolish the law, but He did not come to make us follow the rules made by man either.
Jesus came to show us how to live into the law and into the lives that God wants us to.
If you eat food used in idol worship, then that is not someone elses concern. Although I would like to know where you are getting food used in idol worship…
The Body is held together by Christ, and we are all apart of one another because of Him.
And we are all there because of Him, not because of the rules we keep, or the things we do.
Jesus is the reason we are not condemned. There for let Him judge others. Love them, as He loved you!
