17. If a poor christian that hath a due and tender care of his salvation, do find that under one minister his soul declineth and groweth dead, and under another that is more sound, and clear, and lively, he is much edified to a holy and heavenly frame and life, and if hereupon, preferring his salvation before all things, he remove to that church and minister where he is most edified, without unchurching the other by his censures, this is no sinful separation, but a preferring the one thing needful before all.
18. If one part of the church have leisure, opportunity, cause, and earnest desires to meet oftener for the edifying of their souls, and redeeming their time, than the poorer, labouring, or careless and less zealous part will meet, in any fit place, under the oversight and conduct of their pastors, and not in opposition to the more public, full assemblies, as they did, Acts xii. 12, to pray for Peter at the house of Mary, "where many were gathered together praying;" and Acts x. 1, &c. this is no sinful separation.
19. If a man's own outward affairs require him to remove his habitation from one city or country to another, and there be no greater matter to prohibit it, he may lawfully remove his local communion from the church that he before lived with, to that which resideth in the place he goeth to. For with distant churches and christians I can have none but mental communion, or by distant means (as writing, messengers, &c.); it is only with present christians that I can have local, personal communion.
20. It is possible in some cases that a man may live long without local, personal communion with any christians or church at all, and yet not be guilty of sinful separation. As the king's ambassador or agent in a land of infidels, or some traveller, merchants, factors, or such as go to convert the infidels, or those that are banished or imprisoned. In all these twenty cases, some kind of separation may be lawful.
21. One more I may add, which is, when the temples are so small, and the congregations so great, that there is no room to hear and join in the public worship; or when the church is so excessively great, as to be uncapable of the proper ends of the society; in this case to divide or withdraw, is no sinful separation. When one hive will not hold the bees, the swarm must seek themselves another, without the injury of the rest.
By all this you may perceive, that sinful separation is first in a censorious, uncharitable mind, condemning churches, ministers, and worship causelessly, as unfit for them to have communion with. And secondly, it is in the personal separation which is made in pursuance of this censure: but not in any local removal that is made on other lawful grounds.
_Direct._ IV. Understand and consider well the reasons why Christ so frequently and earnestly presseth concord on his church, and why he so vehemently forbiddeth divisions. Observe how much the Scripture speaketh to this purpose, and upon what weighty reasons. Here are four things distinctly to be represented to your serious consideration. 1. How many, plain, and urgent are the texts that speak for unity, and condemn division. 2. The great benefits of concord. 3. And the mischiefs of discord and divisions in the church. 4. And the aggravations of the sin.
