9. If any by violence will banish or cast out the true bishops or pastors of the church, and set up usurpers in their stead, (as in the Arians' persecution it was commonly done,) it is no culpable separation, but laudable, and a duty, for the people to own their relation to their true pastors, and deny communion with the usurpers: as the people of the eastern churches did commonly refuse communion with the intruding bishops, even to the death, telling the civil rulers, that they had bishops of their own, to whom they would adhere. 10. If a true church will obstinately deny her members the use of any one ordinance of God, as preaching or reading Scripture, or prayer, or praise, or discipline, while it retaineth all the rest, though we may not separate from this church as no church, (which yet in the case of total rejection of prayer or praise, is very questionable at least,) yet if we have opportunity, we must remove our local communion to a more edifying church, that useth all the public ordinances of God: unless the public good forbid, or some great impediment or contrary duty be our excuse. 11. If a true church will not cast out any impenitent, notorious, scandalous sinner, though I am not to separate from the church, yet I am bound to avoid private familiarity with such a person, that he may be ashamed, and that I partake not of his sin.[149] 12. As the church hath diversity of members, some more holy, and some less, and some of whose sincerity we have small hope, some that are more honourable, and some less, some that walk blamelessly, and some that work iniquity; so ministers and private members are bound to difference between them accordingly, and to honour and love some far above others, whom yet we may not excommunicate; and this is no sinful separation.[150] 13. If the church that I live and communicate with, do hold any tolerable error, I may differ therein from the church, without a culpable separation. Union with the church may be continued with all the diversities before mentioned, direct. iii. 14. In case of persecution in one church or city, when the servants of Christ do fly to another, (having no special reason to forbid it,) this is no sinful separation, Matt. x. 23. 15. If the public service of the church require a minister or private christian to remove to another church, if it be done deliberately and upon good advice, it is no sinful separation. 16. If a lawful prince or magistrate command us to remove our habitation, or command a minister from one church to another, when it is not notoriously to the detriment of the common interest of religion, it is no sinful separation to obey the magistrate.
