It should be observed, that when He delivered the Jews from the observance of meats, He then also opened the door to the Gentiles, as Peter was first bidden in the vision to break this law, and was afterwards sent to Cornelius. But if any should ask, how it is that He bade His disciples “go not into the way of the Gentiles,” and yet now Himself walks this way; we will answer, first, that that precept which He had given His disciples was not obligatory on Him; secondly, that He went not to preach, whence Mark even says, that He purposely concealed Himself.
