Brother
mcmurry, this is just a partial answer, but it is for the sake of our brethren we do not do some things also,
1Co 10:27 If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.
1Co 10:28 But if any man say unto you, This is offered in sacrifice unto idols,
eat not for his sake that shewed it, and for conscience sake: for the earth is the Lord's, and the fulness thereof:
1Co 10:29
Conscience, I say, not thine own, but of the other.
We are no longer under law, but we know certain things are taboo to some who are weak; especially those that were under the Old Covenant.
Rom 14:2 For one believeth that he may eat all things: another,
who is weak, eateth herbs.
Rom 14:21 It is good neither to eat flesh, nor to drink wine,
nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
Rom 15:1 We then that are strong ought to bear the infirmities of the weak, and not to please ourselves.
