From The Sermons Of The Apostles:

My second Argument is taken from the Subject of the Sermons of the Apostles, both whilest our Saviour lived on earth, and after his Ascension. The Apostles in our Saviours time were sent, Luke 9.2. to Preach the Kingdome of God: For neither there, nor Mat. 10.7. giveth he any Commission to them, other than this, “As ye go, Preach, saying, the Kingdome of Heaven is at hand;” that is, that Jesus is the Messiah, the Christ, the King which was to come. That their Preaching also after his ascension was the same, is manifest out of Acts 17.6. “They drew (saith St. Luke) Jason and certain Brethren unto the Rulers of the City, crying, These that have turned the world upside down are come hither also, whom Jason hath received. And these all do contrary to the Decrees of Caesar, saying, that there is another King, one Jesus:” And out of the 2.&3. verses of the same Chapter, where it is said, that St. Paul “as his manner was, went in unto them; and three Sabbath dayes reasoned with them out of the Scriptures; opening and alledging, that Christ must needs have suffered, and risen againe from the dead, and that this Jesus (whom he preached) is Christ.”
