John Trapp on John 15:17

Verſe 17. That ye love one another] That ye hold together, becauſe the world will hate you. A ſpirit of perverſities made way for the ruine of Aegypt, Iſai. 19.14, 16, 17. Si collidimur, frangimur, If we claſh, we break, Of the ancient Britains Tacitus tels us, that nothing was ſo deſtructory to them, as their diſſentions, Dum ſinguli pugnant, univerſi vincuncur. And of the Thracians, Herodotus ſaith, that if they had been all of one minde, they had been invincible. Keep therefore the ſtaff of binders unbroken, Zech. 11.7, 14. Keep the unity of the Spirit in the bond of peace, Epheſ. 4.3. In the cauſe of Religion every ſubdiviſion is a ſtrong weapon in the hand of the enemy; as in the diſagreement of Luther and Zuinglius. The Jeſuites have a practice of ruinning over to the Lutherans, pretending to be convers; but it is only to keep up that bitter contention that is between the Calviniſts and Lutherans; the virulency whereof is much fomented by theſe renegado Jeſuites.
