Acts 10:15

What God hath cleansed - God, who made at first the distinction between Jews and Gentiles, has a right to remove it, whenever and by whatever means he pleases: he, therefore, who made the distinction, for wise purposes, between the clean and the unclean, now pronounces all to be clean. He had authority to do the first; he has authority to do the last. God has purposed that the Gentiles shall have the Gospel preached to them: what he therefore has cleansed, "that call not thou common."

What God hath cleansed - What God has pronounced or declared pure. If God has commanded you to do a thing, it is not impure or wrong. Perhaps Peter would suppose that the design of this vision was to instruct him that the distinction between clean and unclean food, as recognized by the Jews, was about to be abolished, Acts 10:17. But the result showed that it had a higher and more important design. It was to show him that they who had been esteemed by the Jews as unclean or profane - the entire Gentile world - might now be admitted to similar privileges with the Jews. That barrier was robe broken down, and the whole world was to be admitted to the same fellowship and privileges in the gospel. See Ephesians 2:14; Galatians 3:28. It was also true that the ceremonial laws of the Jews in regard to clean and unclean beasts was to pass away, though this was not directly taught in this vision. But when once the barrier was removed that separated the Jews and Gentiles, all the laws which were founded on such a distinction, and which were framed to keep up such a distinction, passed away of course. The ceremonial laws of the Jews were designed solely to keep up the distinction between them and other nations. When the distinction was abolished; when other nations were to be admitted to the same privileges, the laws which were made to keep up such a difference received their death-blow, and expired of course. For it is a maxim of all law, that when the reason why a law was made ceases to exist, the law becomes obsolete. Yet it was not easy to convince the Jews that their laws ceased to be binding. This point the apostles labored to establish; and from this point arose most of the difficulties between the Jewish and Gentile converts to Christianity. See Acts 15; and Romans 14-15:

10:15 What God hath purified - Hath made and declared clean. Nothing but what is clean can come down from heaven. St. Peter well remembered this saying in the council at Jerusalem, Acts 15:9 .
