29 That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication: from which if ye keep yourselves, ye shall do well. Fare ye well.
Now in these precepts where it says that no other burden ought to be imposed on Gentile believers except abstinence from the sacrifices of idols, from blood, from what has been suffocated and from fornication, homicide is not forbidden, nor adultery, nor theft, nor homosexual acts, nor other crimes that are punished by divine and human laws. But if it is saying that Christians must observe only that which it has recounted, it will appear to some that it granted license concerning the rest. But consider how the Holy Spirit manages affairs: since other crimes are avenged by laws of the world, it seemed superfluous for those things, which are sufficiently covered by human law, also to have been forbidden by divine law. It only decreed those things about which human law had said nothing and which seemed proper to religion.
"That ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication from which if ye keep yourselves, ye shall do well." For these things the New Testament did not enjoin: we nowhere find that Christ discoursed about these matters; but these things they take from the Law. "From things strangled," it says, "and from blood." Here it prohibits murder. It shows that the rest are not necessary, but superfluous, seeing these things are necessary. "From which if ye keep yourselves," it saith, "ye shall do well." It shows that nothing is lacking to them, but this is sufficient.
From blood, and from things strangled: The use of these things, though of their own nature indifferent, was here prohibited, to bring the Jews more easily to admit of the society of the Gentiles; and to exercise the latter in obedience. But this prohibition was but temporary, and has long since ceased to oblige; more especially in the western churches.
