[The holy Roman Church] also declares that the apostolic prohibition, to abstain from what has been sacrificed to idols and from blood and from what is strangled, was suited to that time when a single church was rising from Jews and gentiles, who previously lived with different ceremonies and customs. This was so that the gentiles should have some observances in common with Jews, and occasion would be offered of coming together in one worship and faith of God and a cause of dissension might be removed, since by ancient custom blood and strangled things seemed abominable to Jews, and gentiles could be thought to be returning to idolatry if they ate sacrificial food. In places, however, where the Christian religion has been promulgated to such an extent that no Jew is to be met with and all have joined the church, uniformly practising the same rites and ceremonies of the gospel and believing that to the clean all things are clean, since the cause of that apostolic prohibition has ceased, so its effect has ceased (Bull of Union with the Copts).
