2. As this unity and peace may consist in the ignorance of many truths, and in the holding some errors, so it must consist with, and it cannot consist without, the believing and practising those things which are necessary to salvation and church communion; and they are, (1.) Believing that Christ the Son of God died for the sins of men. (2.) That whoever believeth ought to be baptized. (3.) The third thing essential to this communion is a holy and a blameless conversation.

(1.) That believing that the Son of God died for the sins of men is necessary to salvation, I prove by these texts, which tell us that he that doth not believe shall be damned (Mark 16:16; John 3:18; 2 Thess 2:12; Rom 10:10).

That it is also necessary to church-communion, appears from Matthew 16:16-18. Peter having confessed that Christ was the Son of the living God, Christ thereupon assures Peter, that upon this rock, viz., this profession of faith, or this Christ which Peter had confessed, he would build his church, and the gates of hell should not prevail against it. And (1 Cor 3:11), the apostle having told the Corinthians they were God's building, presently adds, that they could not be built upon any foundation but upon that which was laid, which was Jesus Christ. All which proves, that Christian society is founded upon the profession of Christ; and not only Scripture, but the laws of right reason, dictate this, that some rules and orders must be observed for the founding all society, which must be consented to by all that will be of it. Hence it comes to pass, that to own Christ as the Lord and head of Christians, is essential to the founding Christian society.

(2.) The Scriptures have declared that this faith gives the professors of it a right to baptism, as in the case of the eunuch (Acts 8), when he demanded why he might not be baptized? Philip answereth, that if he believed with all his heart, he might; the eunuch thereupon confessing Christ, was baptized.

Now, that baptism is essential to church-communion, I prove from 1 Corinthians 12, where we shall find the apostle labouring to prevent an evil use that might be made of spiritual gifts, as thereby to be puffed up; and to think that such as wanted them, were not of the body, or to be esteemed members; he thereupon resolves, that whoever did confess Christ, and own him for his head, did it by the Spirit (v 3), though they might not have such a visible manifestation of it as others had; and therefore they ought to be owned as members, as appears (v 23). And not only because they have called him Lord by the Spirit, but because they have, by the guidance and direction of the same Spirit, been baptized (v 13): 'For by one Spirit we are all baptized into one body,' &c. I need not go about to confute that notion that some of late have had of this text, viz., that the baptism here spoken of is the baptism of the Spirit, because you have not owned and declared that notion as your judgment; but on the contrary, all of you that I have ever conversed with, have declared it to be understood of baptism with water, by the direction of the Spirit. If so, then it follows, that men and women are declared members of Christ's body by baptism, and cannot be by Scripture reputed and esteemed so without it; which farther appears from Romans 6:5, where men, by baptism, are said to be planted into 'the likeness of his death.' And (Col 2:12), we are said to be 'buried with him by baptism.' All which, together with the consent of all Christians, (some few in these late times excepted,) do prove that baptism is necessary to the initiating persons into the church of Christ.

(3.) Holiness of life is essential to church-communion, because it seems to be the reason why Christ founded a church in the world, viz., that men might thereby be watched over and kept from falling; and that if any be overtaken with a fault, he that is spiritual might restore him.

That by this means men and women might be preserved, without blame, to the coming of Christ; and 'the grace of God teacheth us to deny ungodliness and worldly lusts, and to live soberly and uprightly in this present evil world' (Titus 2:11,12). 'And let every one that nameth the name of Christ depart from iniquity' (2 Tim 2:19). And James tells us, speaking of the Christian religion, that 'pure religion, and undefiled, before God—is to visit the fatherless and widows in their affliction, and to keep himself unspotted from the world' (James 1:27). From all which, together with many more texts that might be produced, it appears that an unholy and profane life is inconsistent with Christian religion and society, and that holiness is essential to salvation and church-communion; so that these three things—faith, baptism, and a holy life, as I said before, all churches must agree and unite in, as those things which, when wanting, will destroy their being. And let not any think, that when I say believing the Son of God died for the sins of men is essential to salvation and church-communion, that I hereby would exclude all other articles of the Christian creed as not necessary, as the belief of the resurrection of the dead and eternal judgment, &c.; which, for want of time, I omit to speak particularly to, and the rather because I understand this great article, of believing the Son of God died for the sins of men, is comprehensive of all others, and is that from whence all other articles may easily be inferred.

And here I would not be mistaken, as though I held there were nothing else for Christians to practise, when I say this is all that is requisite to church-communion; for I very well know that Christ requires many other things of us after we are members of his body, which, if we knowingly or maliciously refuse, may be the cause, not only of excommunication, but damnation. But yet these are such things as relate to the wellbeing, and not to the being, of churches; as laying on of hands, in the primitive times, upon believers, by which they did receive the gifts of the Spirit—this, I say, was for the increase and edifying of the body, and not that thereby they might become of the body of Christ, for that they were before. And do not think that I believe laying on of hands was no apostolical institution, because I say men are not thereby made members of Christ's body, or because I say that it is not essential to church-communion. Why should I be thought to be against a fire in the chimney, because I say it must not be in the thatch of the house? Consider, then, how pernicious a thing it is to make every doctrine, though true, the bound of communion; this is that which destroys unity; and, by this rule, all men must be perfect before they can be in peace. For do we not see daily, that as soon as men come to a clearer understanding of the mind of God, to say the best of what they hold, that presently all men are excommunicable, if not damnable, that do not agree with them. Do not some believe and see that to be pride and covetousness, which others do not, because, it may be, they have more narrowly and diligently searched into their duty of these things than others have? What then? must all men that have not so large acquaintance of their duty herein be excommunicated? Indeed, it were to be wished that more moderation in apparel and secular concernments were found among churches; but God forbid, that if they should come short herein, that we should say, as one lately said, that he could not communicate with such a people, because they were proud and superfluous in their apparel.

Let me appeal to such, and demand of them, if there was not a time, since they believed and were baptized, wherein they did not believe laying on of hands a duty; and did they not then believe, and do they not still believe, they were members of the body of Christ? And was not there a time when you did not so well understand the nature and extent of pride and covetousness as now you do? And did you not then believe, and do you not still believe, that you were true members of Christ, though less perfect? Why, then, should you not judge of those that differ from you herein, as you judged of yourselves when you were as they now are? How needful, then, is it for Christians to distinguish, if ever they would be at peace and unity, between those truths which are essential to church-communion, and those that are not!

3. Unity and peace consists in our making one shoulder to practise and put in execution the things we do know. 'Nevertheless, whereto we have—attained, let us walk by the same rule, and mind the same thing' (Phil 3:16). How sad is it to see our zeal consume us, and our precious time, in things doubtful and disputable, while we are not concerned nor affected with the practice of those indisputable things we all agree in! We all know charity to be the great command, and yet how few agree to practise it! We all know they that labour in the Word and doctrine are worthy of double honour; and that God hath ordained, that they which preach the gospel should live of the gospel; these duties, however others have cavilled at them, I know you agree in them, and are persuaded of your duty herein; but where is your zeal to practise? O how well would it be with churches if they were but half as zealous for the great, and plain, and indisputable things, and the more chargeable and costly things of religion, as they are for things doubtful or less necessary, or for things that are no charge to them, and cost them nothing but the breath of contention, though that may be too great a price for the small things they purchase with it.
