Adam Clarke on 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."
