Dr. Martyn Lloyd-Jones on Church Unity

https://www.mljtrust.org/sermons/book-of-ephesians/schism-in-the-church-1/ "I'm a great believer in church unity. I think that these divisions are sinful. What grounds are there for this church unity that you want? Well, the New Testament teaches this. Our Lord's high priestly prayer that they all might be one and that the world might know we are meant to be one and to present this common message to the world. But there is all the difference in the world between a true spiritual biblical New Testament unity and a mere amalgamation of people who call themselves Christian and who disagree violently with one another with regard to the very essentials of the gospel."
