A footnote in my Douay-Rhiems Bible says that the prohibition by the Council at Jerusalem in the Book of Acts against strangled food and blood was an ancient discipline, which, having no purpose anymore, was allowed to lapse long ago.
I guess it probably did refer more to meat sacrificed to idols.
It also seems to me (and this is just a personal observation) like the Apostles held that the 7 commandments given to Noah in Genesis 9 were still binding, even though the law of Moses had been fulfilled by Christ. The Jewish faith holds these ‘Noahide Laws’ as being binding on righteous gentiles as well as Jews,
en.wikipedia.org/wiki/Noahide_laws because they were given to the whole human race when God gave us a ‘new start’ after the flood.
If the Apostles were building on the foundation that Christ had abolished the division between Jews and gentiles, they may have still held that the basic laws for the whole of humanity applied. One of these laws is a prohibition against unnecessary cruelty to animals (not taking meat from a living animal), which may also be a reason for the prohibition against strangled meat and blood. I think the way we treat animals is pretty important personally, because the way we treat the animals under our stewardship ought to echo the way God treats His human flock. That’s why I rarely eat meat (will have turkey at Christmas to avoid family arguments) and am careful where my eggs come from.
Though I’ve got to say, I do miss good old fashioned British black pudding with bacon, sausage and eggs on a Sunday morning!
