Thank you very much for your well thought out response. By taboo, what was meant by me, are those relationship, sexual, that are not allowed, phrased in the OT as “you shall not see your xxxx nakedness”. Agree completely with you that those verses from Leviticus are being, and have been, terribly misused, if not abused. Not being Christian, what various Christians do with it does not bother me, as long as they leave me alone, something, that given their history, is not a likely outcome.
The disciples being Jewish, would have been raised knowing the Law, whether they practiced it or not was another thing. They would have known what seeds can be sown together, what fabrics could be used for cloth, what foods were kosher, what tithes were owed, etc., this is pretty basic stuff, and being raised around and in it, it would have been just part of their everyday consciousness. In the Talmud, there is a whole classification, for those who are questionable about upholding the Law strictly. Since Christianity preaches that only Jesus can give the Law, all other laws are henceforth overridden, and abolished, why they adhere to those two, fragments(?), is beyond me. Then again, religion is not necessarily a strictly logical understanding.
