LOL How about they follow the New Testament prohibitions?
Acts 15:29 That ye abstain from meats offered to idols, and from blood,
John 6:63 The Spirit gives life; the flesh counts for nothing.
The first is given by the same Church that offers the Eucharist, which is flesh and blood of Christ. We don’t go to pagan services today, let alone eat there.
The second is the Catholic teaching: the Holy Eucharist “profits” the spirit not the flesh.
I have never eaten meat that I knew was offered to an idol and it is impossible to eat meat without consuming some blood....maybe cooked dry, but blood nevertheless.
