THE SHORT VERSION: The church of Christ believes, follows, and stands for what the Bible teaches—and whatever the Bible teaches—regardless of any temporal circumstances.
But here are some of the more specific things we stand to defend:
1. There is One God, manifested in three persons. The Father, the Son (formerly known as the Word—Jn. 1:1,14), and the Spirit.
2. There is salvation in no other name given among men but Jesus Christ (Acts 4:12).
3. Salvation (i.e., from one’s past sins—cf. Rom. 13:11) is attained as a result of:
a. Hearing/Believing the Gospel (Rom. 10:10-17);
b. Repenting (turning away from, exiting, ceasing) of current/past sins (Acts 2:38; Lk. 13:3,5);
c. Confessing the Divine Sonship of Jesus (Rom. 10:10);
d. Being Immersed in Water, “unto [in order to] the remission of sins” [cp. Matt. 26:28 & Acts 2:38] (Acts 2:38; 22:16; Mk. 16:16; Jn. 3:3-7; Rom. 6:3-7; Gal. 3:27; 1 Pet. 3:21). At this point, the sincere soul is cleansed of his past sins (Acts 22:16), and he is added to the one and only (now and forever) kingdom of Jesus Christ—he is added to the Lord, Himself (Gal. 3:27), by the Lord, Himself (Acts 2:47).
4. Salvation (i.e., continuous cleansing) is maintained by living faithfully and sincerely for the Lord—to the very best of one’s ability (cf. Rom. 4:3; Gen. 15:6)—unto death (Jn. 3:36; 2 Cor. 5:15; 1 Jn. 1:7; Rev. 2:10).
5. The worship of the New Testament church is simple and plain, and is regulated—both permissively and prohibitively—by the written word of God (see 2 Cor. 4:6). The church which God purposed, prophesied, and planned, and which Jesus prepared, promised, and purchased with His blood worshiped Jehovah God by means of prayer, song (without mechanical accompaniment), preaching/studying Scripture, partaking of the Lord’s Supper (each Lord’s day—cf. Acts 20:7; 1 Cor. 16:2), and giving of their means to support the various works with which the local congregation is involved.
