Note here, that communion is one thing, and subjection is another. It is not your subjection to other churches that is required to your communion with them. The churches that Paul wrote to at Rome, Corinth, Galatia, Ephesus, Philippi, &c. had communion together according to their capacities in that distance; but they were not subject one to another, any otherwise than as all are commanded to be subject to each other in humility, 1 Pet. v. 5. The church of Rome now accuseth all the christians in the world of separating from their communion, unless they will take them for their rulers, and obey them as the mistress church: but Paul speaketh not one syllable to any of the churches of any such thing, as their obedience to the church of Rome. To your own pastors you owe subjection statedly as well as communion; and to other pastors of the churches of Christ (fixed or unfixed) you owe a temporary subjection so far as you are called to make use of them (as sick persons do to another physician, when the physician of the hospital is out of the way): but one church is not the ruler of another, or any one of all the rest, by any appointment of the King of the church. _Direct._ III. By the help of what is already said, you are next distinctly to understand how far you are bound to union or communion with any other church or person, and what distance, separation, or division is a sin, and what is not: that so you may neither causelessly trouble yourselves with scruples, nor trouble the church by sinful schism. [Sidenote: What unity is among all christians.] I. There must be a union among all churches and christians in these particulars. 1. They have all but one God. 2. And one Head and Saviour, Jesus Christ. 3. And one Sanctifier, the Holy Ghost. 4. And one ultimate end and hope, even the fruition of God in heaven. 5. And one gospel to teach them the knowledge of Christ, and contain the promise of their salvation. 6. And one kind of faith that is wrought hereby. 7. And one and the same covenant (of which baptism is the seal) in which they are engaged to God. 8. And the same instrumental founders of our faith, under Jesus Christ, even the prophets and apostles. 9. And all members of the same universal body. 10. And all have the same new nature and holy disposition, and the same holy affections, in loving God and holiness, and hating sin. 11. They all own, as to the essential parts, the same law of God, as the rule of their faith and life, even the sacred canonical Scriptures. 12. Every member hath a love to the whole, and to each other, especially to the more excellent and useful members; and an inclination to holy communion with each other. 13. They have all a propensity to the same holy means and employment, as prayer, learning the word of God, and doing good to others.[140] All these things the true living members of the church have in sincerity, and the rest have in profession.
