它不承认其它任何宗派是基督的教会，不论英国圣公会，或非国教的新教派，它一概都不承认。达秘在公开的文字上与私人的信件中反复说明：唯有属于他一会的人，才组成伦敦市的真正教会。

没人见过一个达秘的粉丝，参加我们的圣经班、宣教聚会、或其它福音团契。不论别人信仰多么纯正、正统，多么敬虔、爱主，弟兄会还是基本上视他们为非正统的旁门左道，并且在教会管理上出了差错，所以，他们相信，与别人在事工上同负一轭是有罪的。

这种执着的信念，自然导致了他们属灵的骄傲。他们相信在所有的宗派群体中，唯有他们获得了真理的知识。所以，他们很顺理成章，居高临下，可怜其它的基督教派。不但如此，他们自己的一些成员承认，他们甚至鄙视别人。

这种优越感，自然导致了他们的骄傲自负、唯我独尊，以致与他们意见相左的人，往往很受不了。这种心态，在达秘的身上，更是一览无遗：他呈现出一副绝对无误的样子。

基本上，达秘先生是新教里的、一个彻头彻尾的教皇。他永远不会承认自己的错误，所以，当有人挑战他神学的正确性时，他也自然置若罔闻、拒绝争辩。是的，这也是很合情合理的。”（司布真）

原文如下： Charles Spurgeon on Darby Brethrenism

"Plymouth Brethren (referring to the Closed Brethren of Darby) have no feeling wherever their principles are concerned. I know indeed of no sect or denomination so utterly devoid of kindness of heart. It is the most selfish religious system with which I am acquainted. It is entirely wrapped up in itself.

It recognizes no other denomination, whether the Church of England, or either of the Nonconformist denominations, as a church of Christ. Mr. Darby has again and again said in print, as well as written in private, that those who belong to his party in the metropolis, constitute the only church of Christ in London. . . .

No one ever saw a Darbyite at any of our Bible, or Missionary, or other Evangelical Society meetings. The Brethren look upon all other denominations, however evangelical in sentiment, and however high their standard of personal religion, as so largely infected with error in doctrine, as well as wrong in relation to church government, that they believe it would be sinful to associate with them for the promotion of religious ends. And this conviction, which is never absent from their minds, naturally has the effect of puffing them up with spiritual pride. Believing that they alone of all religious bodies have attained to the knowledge of the truth, it could hardly be otherwise than that they should look down on every other Christian sect with supreme pity, mingled, even according to the admission of some of their own number, with contempt. . . .

With this feeling is naturally associated an amount of arrogance in the assertion of their own views, which those who differ from them often find to be unbearable. And in this respect their leader, Mr. Darby, sets them an example.

In his case it assumes the form of infallibility.

Mr. Darby is, to all intents and purposes a thorough Pope, though under a Protestant name. He will never admit that he is in error; and therefore very naturally declines to argue with those who controvert the soundness of his views. How, indeed, could it be otherwise?"
