_Direct._ VIII. Keep right apprehensions of the excellency of charity and unity among believers, and receive nothing hastily that is against them; especially take heed lest under pretence of their authority, their number, their soundness, or their holiness, you too much addict yourselves to any sect or party, to the withdrawing of your special love and just communion from other christians, and turning your zeal to the interest of your party, with a neglect of the common interest of the church; but love a christian as a christian, and promote the unity and welfare of them all.[61]
Use often to read and well consider the meaning and reason of those many urgent passages in Scripture, which exhort all christians to unity and love.[62] Such as John xi. 52; xvii. 11, 21-23; 1 Cor. iii. 10, 17; xii. throughout; 2 Cor. xi. 13; 1 Thess. v. 12, 13; Phil. ii. 1-3; 1 Pet. iii. 8; Rom. xvi. 17; 1 Cor. i. 10; iii. 3; xi. 18. And John xiii. 35; Rom. xii. 9, 10; xiii. 10; 2 Cor. xiii. 11; Gal. v. 6, 13, 22; Col. i. 4; 1 Thess. iv. 9; 1 John iii. 11, 14, 23; iv. 7, 11, 16, 19-21. Surely if the very life of godliness lay not much in unity and love, we should never have had such words spoken of it, as here you find. Love is to the soul, as our natural heat is to the body: whatever destroyeth it, destroyeth life; and therefore cannot be for our good. Be certain, that opinion, course, or motion, tends to death, that tends to abate your love to your brethren, much more which under pretence of zeal, provoketh you to hate and hurt them. To divide the body is to kill it or to maim it; dividing the essential, necessary parts, is killing it; cutting off any integral part, is maiming it. The first can never be an act of friendship, which is the worst that an enemy can do: the second is never an act of friendship, but when the cutting off a member which may be spared is of absolute necessity to the saving of the whole man, from the worse division between soul and body. By this judge what friends dividers are to the church, and how well they are accepted of God.
He that loveth any christian aright, must needs love all that appear to him as christians. And when malice will not suffer men to see christianity in its profession, and credible appearance in another, this is as well contrary to christian love, as hating him when you know him to be a true christian. Censoriousness (not constrained by just evidence) is contrary to love, as well as hatred is.
There is a union and communion with christians as such: this consisteth in having one God, one Head, one Spirit, one faith, one baptismal covenant, one rule of holy living, and in loving and praying for all, and doing good to as many as we can. This is a union and communion of mind, which we must hold with the catholic church through the world. And there is a bodily local union and communion, which consisteth in our joining in body, as well as mind, with particular congregations: and this, as we cannot hold it with all, nor with any congregation, but one at once; so we are not bound to hold it with any, that will drive us from it, unless we will commit some sin:[63] statedly we must hold it with the church which regularly we are joined to, and live with; and occasionally we must hold it with all others, where we have a call and opportunity, who in the substance worship God according to his word, and force us not to sin in conformity to them. It is not schism to lament the sins of any church, or of all the churches in the world: the catholic church on earth consists of sinners. It is not schism to refuse to be partaker in any sin of the purest church in the world: obedience to God is not schism. It is not schism that you join not bodily with those congregations where you dwell not, nor have any particular call to join with them; nor that you choose the purest and most edifying society, rather than one that is less pure and profitable to you; _cæteris paribus_, supposing you are at liberty: nor that you hold not bodily communion with that church, that will not suffer you to do it, without sinning against God; nor that you join not with the purest churches, when you are called to abide with one less pure.
