John Trapp on John 17:21

Verſe 21. That they all may be one] Though not by the ſame kinde of union, whereby the Father and Sonne are one, yet by an union every way as reall and indiſſoluble; ſuch, as whereby the world may be convinced that Chriſt is the very Meſſiah, and the faithfull, the true Church. So it was acknowledged in the Primitive times, Act. 4 32. But what a ſad thing was it, that a Heathen ſhould ſoon after have cauſe to ſay, Am Marcellinus l 2. c. 2. Triſt iſſima illa perſecur to ſub Diocletiano, poreſſ. or ta eſt a petulantia, ſuperbia & rixis ſacerdotum. Euſeb. 2 Cor. 3 ul[illegible: 1 letter]. Epheſ. 2 6. Heb 6, 2. [non-Latin text not transcribed] Nullae infestae hominibus beſtiae, ut ſunt ſibi ferales pleri que Christiani; No beaſts are ſo miſchievous to men, as Chriſtians are one to another. They had not ſo learned Chriſt. Love and humility are his cognizances. Why then ſhould the Turk have occaſion to ſay, that he ſhould ſooner ſee his fingers all of a length, then Chriſtian Princes all of a minde? Why ſhould the Jew ſtumble at our diſſenſions, which is one of the main ſcandals they take from Proteſtants?
