I’m sure that many of these points have already been mentioned, but it is useful to compare findings when they have been independently established.
Gentiles not prohibited to eat unbled meat
Under the Law of Moses, the alien residents (those who were not proselytes) were totally at liberty to eat blood according to Deuteronomy 14:21. What is interesting about that scripture is the fact that God Himself gave permission to sell meat with blood in it to those not under the Law. He could have enforced a nationwide ban, but chose not to.
God anointed Gentiles with the Holy Spirit regardless of the fact that they ate unbled meat
It is of great importance to note that Jehovah accepted the Gentiles and anointed them with Holy Spirit, despite the fact that they were at liberty to eat unbled meat according to the Law. (Acts 10:3-4,15 ; 11:1-18 ; 15:7-9)
13 years
According to the Watchtower’s chronology, there was a period of 13 years between the first Gentile conversion to Christianity, and the Council of Jerusalem, when the issue of the Law was raised. As mentioned above, during those years they were totally at liberty to eat unbled meat.
If it really was so important to the will of God, why did He not inform the Gentiles of His stipulations regarding blood and the Law right at the beginning of their conversion? God was in direct communication with Peter, so adding one more detail to the mix would not have been a big issue.
It makes no sense that He would wait for 13 years before deciding to inform the congregations.
Jewish Christian sensibilities was the only reason why the issue of the Law was raised. It did not originate from God
The issue of the Law was raised only because of the fact that some ‘unauthorised’ Jewish Christians took it upon themselves to insist that the Gentile brothers were to observe the Law. (Acts 15:1,5,24)
Had those Jewish converts understood that the Law had been fulfilled, they would have accepted that the Gentiles were not obligated to adhere to any part of it.
Hence, there is every reason to conclude that things would have simply continued as they had for the previous 13 years.
The use of the word ‘ABSTAIN’
The Cambridge Dictionary defines ‘abstain’ as follows :-
“to not do something that you could do… If you abstain from voting, you do not vote although you are permitted to vote.”
In light of the points above, the use of the word ‘abstain’ is significant owing to the fact that the Gentile Christians had been free to eat meat with blood in it for the previous 13 years.
It is not the same as a command. It is asking people to voluntarily refrain from doing something that they could otherwise do. The language used in the decisions made at the Council of Jerusalem contrasts significantly with the language found in Leviticus.
Paul’s letters also contradict the notion that the word ‘abstain’ was considered to be a commend.
Acts 15:29 says in part:-
“to keep abstaining from things sacrificed to idols…”
6 years after the Council of Jerusalem, Paul readdressed the issue of food offered to idols in his letter to the Corinthians. (1 Corinthians chapters 8 & 10) Had Paul understood the decisions to be a command, he would have simply reiterated that food offered to idols was not to be consumed as it was against God’s law.
Paul said no such thing.
Instead, he made it clear that food offered to idols was perfectly acceptable, so long as it didn’t stumble the conscience of a fellow believer. (1 Cor 8:7,9-11)
Therefore, with regards to food offered to idols, the word ‘abstain’ could not have been a Divine command.
Around the same time, in his letter to the Romans, Paul also clarified “that nothing (no food) is defiled in itself; only where a man considers something to be defiled, to him it is defiled.” (Romans 14:14) There is no reason to conclude that Paul’s counsel is not inclusive of ‘things sacrificed to idols and from blood and from things strangled’, considering his letter to Corinth.
Obviously, fornication was considered unbefitting for Gentile Christians. On the other hand, the dietary requirements of Acts 15 are debatable.
There is a lot more that could be said.
