Verse 21 of Acts 15 explains the reason for the command to abstain from blood. Abstain from blood BECAUSE there are synagogues all over the world where people follow Moses and have had their conscience sensitized to eating only Kosher foods. That would be the least that Gentile Christians could do to accommodate their Jewish brothers. It would ease the fellowship between Jews and Gentiles. So much fellowship involves sharing meals together etc. If a Gentile and a Jew were in "field service" together preaching in public places and it was time to have lunch it would be wrong for a Gentile to buy some blood sausage and start gnawing away in front of his Jewish brother. Likewise, temples made money selling meat that had been offered to idols. A Christian could partake of that food but it would be wrong to do so in front of a newly converted Gentile who's weak conscience might be offended.
Notice: there is no scripture that says those who eat blood will not inherit the kingdom of heavens. Acts 15:21 suggested no congregational action for those who would fail to abstain from the listed food items. The Watchtower article comes to the false conclusion that because "FORNICATION" is forbidden in the same verse as these dietary restrictions that they all carry the same sinful weight. Just because several things are associated in the same context doesn't mean that they are all equal. If that were true then The Father, Son and Holy Spirit are equal by virtue of their being listed together. Fornication was thrown in because that was a serious problem in Gentile lands.
They (Watchtower) don't have a leg to stand on when it comes to this God dishonoring deadly policy.
