The catholic or universal church may be called invisible in terms of the internal work of the Spirit. The universal church consists of the whole number of the elect from the past, present, and future. They will be gathered into one, under Christ, its head. The church is the spouse, the body, and the fullness of him who fills all in all.1
All persons throughout the world who profess faith in the gospel and practice obedience to God by Christ according to it, who have not destroyed their own profession by any foundational errors or unholiness, are and may be called visible saints.2 Individual congregations ought to be composed of those who profess such faith.3
The purest churches under heaven are subject to mixture and error.4 Some have so degenerated so as to become no churches of Christ but synagogues of Satan.5 Nevertheless, Christ has always had and ever will have a kingdom in this world until its end, a kingdom of those who believe in him and profess his name.6
The Lord Jesus Christ is the Head of the Church. By the Father’s appointment, all authority is invested in him in a supreme and sovereign manner for the calling, institution, order, and government of the church.7
The Lord Jesus, in the execution of this power with which he is so entrusted, calls those who are given to him by his Father8 out of the world to himself, through the ministry of his word, by his Spirit. He calls them, that they may walk before him in all the ways of obedience, which he prescribes to them in his word.9 He commands those thus called to walk together in particular communities, or churches, for their mutual edification and the proper execution of public worship, which he requires of them in the world.10
The members of these churches are saints by calling, visibly demonstrating and evidencing (in and by their profession and walking) their obedience to the call of Christ.11 They willingly consent to walk together, according to the appointment of Christ, giving themselves up to the Lord and one to another by the will of God, in professed subjection to the ordinances of the Gospel.12
To each of these churches thus gathered, according to the mind of Christ declared in his word, he has given power and authority. This power and authority is necessary to carry out in good order the worship and discipline God has instituted for them to observe. Along with this power and authority, God gave commands and rules for the proper and right exerting and executing of it.13
A particular church, gathered and completely organized according to the mind of Christ, consists of officers and members. The officers appointed by Christ are to be chosen and set apart by the church (called and gathered) for the administration of the sacraments and execution of power or duty to which he entrusts or calls them. The two offices of elder (also called overseer and pastor) and deacon continue to the end of the world.14 For the health of the particular church and from scriptural examples, it is ideal that there is a plurality of qualified overseers or elders.15 While not every church is able to have a plurality of overseers or elders, each local church should strive toward the ideal.
The way appointed by Christ for the calling of any person, fitted and gifted by the Holy Spirit, to the office of elder in a church, is that he be affirmed by the church itself.16 He is to be solemnly set apart by prayer with the laying on of hands by the eldership of the church, if the church already has elders.17 Deacons should be likewise affirmed by the church and set apart by prayer and the laying on of hands.18
The work of pastors is constantly to attend to the service of Christ in his churches in the ministry of the word and prayer, watching over their souls as those who must give an account to him.19 Therefore, it is incumbent on the churches to whom they minister, not only to give them all due respect, but also to share with them from all their good things according to their ability.20 This is so that the pastors may have a comfortable supply without being entangled in secular affairs21 and may also be capable of exercising hospitality towards others.22 Such provision is required by the law of nature and by the express order of our Lord Jesus, who has ordained that those who preach the Gospel should earn their living by the Gospel.23
It is essential that the pastors of the churches preach the word as a function of their office, but the work of preaching is not limited to pastors only. Other men gifted and fitted by the Holy Spirit and approved and called by the church may and ought to preach.24
All believers are bound to join themselves to particular churches when and where they have the opportunity, so that all who are admitted to the privileges of a church are also under its censures and government, according to the rule of Christ.25
If any offense is taken by church members and they have performed their duty required of them toward the person who offended them, they should not disturb any church order or remove themselves from the assemblies of the church or administration of any sacraments because of the account of such offense at any of their fellow members. Instead, they are to wait upon Christ in the further actions of the church.26
Each church and all the members of it are bound to pray continually for the good and prosperity of all the churches of Christ27 in all places and upon all occasions to further it. Everyone within the bounds of their places and callings are to exercise their gifts and graces for the benefit of every church. Churches planted by the providence of God, as they enjoy opportunity and advantage for it, should hold fellowship among themselves, for their peace, increase of love, and mutual edification.28
The unity of the Church as a single body with Christ as its head should be manifest in partnership. Therefore, it is appropriate for particular churches to unite with other churches for fellowship, accountability, and cooperation in mission and training.29
The exemplary council of the early church in Jerusalem commends the regular gathering of the elders of churches in partnership for various purposes.30
Such partnerships are voluntary and are thus established by the mutual consent of the particular churches. The authority of these assemblies shall be such as is agreed upon by the churches through their ordained elders and shall pertain to such things as ordination, the discipline of elders, appeals for church discipline, and shared participation in mission.
