I have done an long article on this at http://jwfacts.com/index_files/blooddoctrine.htm
There is nothing wrong with eating things strangled. In the Jewish Law things strangled could be sold to non Israelites.
At Acts 21:25 it recommended that ‘the believers from among the nations’ observe fours things from the Mosaic Law
““As for the believers from among the nations, we have sent out, rendering our decision that they should keep themselves from what is sacrificed to idols as well as from blood and what is strangled and from fornication.””
This is not an exhaustive list of things to abstain from (murder being obvious omission) so why was this unusual list given. It was to prevent stumbling Jewish brothers. This was explained in the Watch Tower 1909 April 15 pp. 116-117 and is the common Christian understanding. The New Catholic Encyclopaedia states;
“These four prohibitions were imposed for the sake of charity and union. As they forbade practices which were held in special abhorrence by all the Jews, their observance was necessary to avoid shocking the Jewish brethren and to make free intercourse between the two classes of Christians possible….
With the disappearance of the Jewish-Christian community of Jerusalem at the time of the rebellion (A.D. 67-70), the question about circumcision and the observance of the Law ceased to be of any importance in the Church, and soon became a dead issue.” (The Catholic Encyclopedia, Volume VIII Copyright © 1910 by Robert Appleton Company Online Edition Copyright © 2003 by K. Knight as displayed at http://www.newadvent.org/cathen/08537a.htm 17/09/2005)
How do both scholars and Russell reach this conclusion? Firstly, as the Mosaic Law had ceased to apply it does not make sense for Christians to be required to retain only this portion of it. Particularly is this so when considering that these four things are not the only Mosaic rules that a Christian must follow, nor are they the most important ones.
James explained why the four things mentioned at Acts 15:20 were specifically chosen in the very next verse.
Acts 15:19-21
” 1 Hence my decision is not to trouble those from the nations who are turning to God, 20 but to write them to abstain from things polluted by idols and from fornication and from what is strangled and from blood. 21 For from ancient times Moses has had in city after city those who preach him, because he is read aloud in the synagogues on every sabbath. ”
The words of Moses that were read in Synagogues every Sabbath is the passage from Lev 17:1 to 18:27. Leviticus 17 and 18 has the same four requirements, listed in the exact order as that given in Acts 15. These were the compulsory rules for both Israelites and foreigners living in ancient Israel. This is why these four items meant so much to the Judaizers. Hence the Apostles felt abstinence was necessary in order to prevent stumbling within the surrounding Jewish congregations.
Paul specifically states that there is nothing wrong with eating food sacrificed to idols. Paul explains that this prohibition was in order to not stumble others. This was an issue in congregations that were having trouble between Judaizers and Gentiles. The same principal can apply to blood.
1 Corinthians 8:4-13
“ Now concerning the eating of foods offered to idols, we know that an idol is nothing in the world , and that there is no God but one… Nevertheless, there is not this knowledge in all persons; but some, being accustomed until now to the idol, eat food as something sacrificed to an idol, and their conscience, being weak, is defiled. 8 But food will not commend us to God ; if we do not eat, we do not fall short, and, if we eat, we have no credit to ourselves. 9 But keep watching that this authority of YOURS does not somehow become a stumbling block to those who are weak. 10 For if anyone should see you, the one having knowledge, reclining at a meal in an idol temple, will not the conscience of that one who is weak be built up to the point of eating foods offered to idols? 11 Really, by your knowledge, the man that is weak is being ruined, [your] brother for whose sake Christ died. 12 But when YOU people thus sin against YOUR brothers and wound their conscience that is weak, YOU are sinning against Christ. 13 Therefore, if food makes my brother stumble, I will never again eat flesh at all, that I may not make my brother stumble. ”
1 Corinthians 10:25-33
“ Everything that is sold in a meat market keep eating , making no inquiry on account of YOUR conscience; 26 for “to Jehovah belong the earth and that which fills it.” 27 If anyone of the unbelievers invites YOU and YOU wish to go, proceed to eat everything that is set before YOU, making no inquiry on account of YOUR conscience. 28 But if anyone should say to YOU: “This is something offered in sacrifice,” do not eat on account of the one that disclosed it and on account of conscience. 29 “Conscience,” I say, not your own, but that of the other person. For why should it be that my freedom is judged by another person’s conscience? 30 If I am partaking with thanks, why am I to be spoken of abusively over that for which I give thanks? 31 Therefore, whether YOU are eating or drinking or doing anything else, do all things for God’s glory. 32 Keep from becoming causes for stumbling to Jews as well as Greeks and to the congregation of God, 33 even as I am pleasing all people in all things, not seeking my own advantage but that of the many, in order that they might get saved.”
Even though the decree at Acts 15 says to abstain from eating food sacrificed to idols Paul makes clear that there is nothing wrong with this practice. He said it was only wrong when it stumbled the brothers, in this case the Judaizers. Acts 15 included food sacrificed to idols, blood and animals strangled because they caused stumbling in the mixed congregations due to their being read “in the Synagogue on every Sabbath”, not because they are offensive to God. This became less of an issue after the destruction of the temple in 70 A.D. and holds no relevance in our era.
Abstaining from blood is never mentioned in any other context in the New Testament. It is never discussed as a reason to shun a brother. Paul does not mention eating blood at 1 Corinthians 5 as a reason to ‘quit mixing’ with a brother, neither does John mention it. In Revelation 21:8 and 1 Corinthians 6 blood is not said to be a reason for not inheriting God’s Kingdom. If avoiding blood was a key requirement of God it would be mentioned alongside sins such as fornication, murder and idolatry that are repeatedly condemned in the New Testament.
