Concerning the Swearing of Oaths we believe and confess, that the Lord Christ has set aside and forbidden, the same to his disciples, that they should not swear at all, but that yea should be yea, and nay, nay; from which we understand that all oaths, high and low, are forbidden, and that instead of them we are to confirm all our promises and obligations, yea, all our declarations and testimonies of any matter, only with our word yea, in that which is yea, and with nay, in that which is nay; yet, that we must always, in all matters, and with every one, adhere to, keep, follow, and fulfill the same, as though we had confirmed it with a solemn oath. And if we do this, we trust that no one, not even the Magistracy itself, will have just reason, to lay a greater burden on our mind and conscience. Matt. 5:34,35; James 5:12; 2 Cor. 1:17.
We also believe in, and confess, a ban, Separation, and Christian correction in the church, for amendment, and not for destruction, in order to distinguish that which is pure from the impure: namely, when any one, after he is enlightened, has accepted the knowledge of the truth, and been incorporated into the communion of the saints, sins again unto death, either through willfulness, or through presumption against God, or through some other cause, and falls into the unfruitful works of darkness, thereby becoming separated from God, and forfeiting the kingdom of God, that such a one, after the deed is manifest and sufficiently known to the church, may not remain in the congregation of the righteous, but, as an offensive member and open sinner, shall and must be separated, put away, reproved before all, and purged out as leaven; and this for his amendment, as an example, that others may fear, and to keep the church pure, by cleansing her from such spots, lest, in default of this, the name of the Lord be blasphemed, the church dishonored, and offense given to them that are without; and finally, that the sinner may not be condemned with the world, but become convinced in his mind, and be moved to sorrow, repentance and reformation. Jer. 59:2; 1 Cor. 5:5,13; 1 Tim. 5:20; 1 Cor. 5:6; 2 Cor. 10:8; 13:10.
Further, concerning brotherly reproof or admonition, as also the instruction of the erring, it is necessary to exercise all diligence and care, to watch over them and to admonish them with all meekness, that they may be bettered, and to reprove, according as is proper, the stubborn who remain obdurate; in short, the church must put away from her the wicked (either in doctrine or life), and no other. James 5:19; Tit. 3:10; 1 Cor. 5:13.
