Why have a church?
Why are believers formed into a church? Because by this means Christ would increase their usefulness in the world and strengthen their personal influence for good.—Letter 26, 1900 (February 15); 3SM 16PCL 22.2
The church is God’s appointed agency for the salvation of men. It was organized for service, and its mission is to carry the gospel to the world. From the beginning it has been God’s plan that through His church shall be reflected to the world His fullness and His sufficiency. The members of the church, those whom He has called out of darkness into His marvelous light, are to show forth His glory. The church is the repository of the riches of the grace of Christ; and through the church will eventually be made manifest, even to “the principalities and powers in heavenly places,” the final and full display of the love of God. (Ephesians 3:10).—AA 9 (1911)PCL 22.3
Members are a family—Believers are to shine as lights in the world. A city set on a hill cannot be hid. . . . The members are pledged to be separate from the world, consecrating their service to one Master, Jesus Christ. They are to reveal that they have chosen Christ as their leader. . . . The church is to be as God designed it should be, a representative of God’s family in another world.—Letter 26, 1900 (February 15); 3SM 17PCL 22.4
The church is a Christian society formed for the members composing it, that each member may enjoy the assistance of all the graces and talents of the other members, and the working of God upon them, according to their several gifts and abilities. The church is united in the holy bonds of fellowship in order that each member may be benefited by the influence of the other. All are to bind themselves to the covenant of love and harmony. The Christian principles and graces of the whole society of believers are to gather strength and force in harmonious action. Each believer is to be benefited and improved by the refining and transforming influence of the varied capabilities of the other members, that the things lacking in one may be more abundantly displayed in another. All the members are to draw together, that the church may become a spectacle to the world, to angels, and to men.—Letter 26, 1900 (February 15); 3SM 15, 16PCL 23.1
The Lord’s body—God is seeking to make His church the continued incarnation of Christ. The gospel ministers are the undershepherds, Christ is the divine shepherd. The members of the church are the working agencies of the Lord. His church will stand out prominently. It is the Lord’s body.—Letter 121, 1900 (August 13)PCL 23.2
The Lord has provided His church with capabilities and blessings, that they may present to the world an image of His own sufficiency, and that His church may be complete in Him, a continual representation of another, even the eternal world, of laws that are higher than earthly laws. His church is to be a temple built after the divine similitude, and the angelic architect has brought his golden measuring rod from heaven, that every stone may be hewed and squared by the divine measurement and polished to shine as an emblem of heaven, radiating in all directions the bright, clear beams of the Sun of Righteousness. The church is to be fed with manna from heaven and to be kept under the sole guardianship of His grace. Clad in complete armor of light and righteousness, she enters upon her final conflict. The dross, the worthless material, will be consumed, and the influence of the truth testifies to the world of its sanctifying, ennobling char- acter.—GCDB, February 27, 1893; TM 17, 18PCL 23.3
