We believe and profess, one catholic or universal Church, which is an holy congregation, of true Christian believers, all expecting their salvation in Jesus Christ, being washed by His blood, sanctified and sealed by the Holy Ghost. This Church hath been from the beginning of the world, and will be to the end thereof; which is evident from this, that Christ is an eternal King, which, without subjects, cannot be. And this holy Church is preserved or supported by God, against the rage of the whole world; though she sometimes (for a while) appears very small, and in the eyes of men, to be reduced to nothing: as during the perilous reign of Ahab, the Lord reserved unto Him seven thousand men, who had not bowed their knees to Baal. Furthermore, this holy Church is not confined, bound, or limited to a certain place or to certain persons, but is spread and dispersed over the whole world; and yet is joined and united with heart and will, by the power of faith, in one and the same spirit.
Article 28 - That every one is bound to join himself to the true Church
We believe, since this holy congregation is an assembly of those who are saved, and that out of it there is no salvation, that no person of whatsoever state or condition he may be, ought to withdraw himself, to live in a separate state from it; but that all men are in duty bound to join and unite themselves with it; maintaining the unity of the Church; submitting themselves to the doctrine and discipline thereof; bowing their necks under the yoke of Jesus Christ; and as mutual members of the same body, serving to the edification of the brethren, according to the talents God has given them. And that this may be the more effectually observed, it is the duty of all believers, according to the Word of God, to separate themselves from all those who do not belong to the Church, and to join themselves to this congregation, wheresoever God hath established it, even though the magistrates and edicts of princes were against it, yea, though they should suffer death or any other corporal punishment. Therefore all those, who separate themselves from the same, or do not join themselves to it, act contrary to the ordinance of God.
Article 29 - Of the marks of the true Church, and wherein she differs from the false church
We believe, that we ought diligently and circumspectly to discern from the Word of God which is the true Church, since all sects which are in the world assume to themselves the name of the Church. But we speak not here of hypocrites, who are mixed in the Church with the good, yet are not of the Church, though externally in it; but we say that the body and communion of the true Church must be distinguished from all sects, who call themselves the Church. The marks by which the true Church is known, are these: if the pure doctrine of the gospel is preached therein; if she maintains the pure administration of the sacraments as instituted by Christ; if church discipline is
