Which church is the right church? The answer is simple: the one that follows the Bible completely. The Bible is the complete word of God and furnishes us with everything we need to serve him (2 Tim. 3:16-17; 2 Pet. 1:3). There is no additional revelation from God to man. God, through the Holy Spirit, delivered his will to man in the first century and that will has been recorded and providentially preserved for all mankind (Jn. 16:13; Jude 3; 1 Pet. 1:25).
The Bible teaches that Christ only has only one church (Eph. 4:4 ff; 1:22-23; Mt. 16:18). When we confess our faith in Jesus Christ as the Son of God, repent of our sins, and are baptized in water for the remission of our sins, then the Lord adds us to his church (Rom. 10:10 f; Acts 2:3 8,47). There is just one church, and the person who obeys the gospel of Christ becomes a part of that body. (1 Cor 12:27) He can then wear the name Christian, because then and only then is he truly a follower of Christ (Acts 11:26).
Must Be Right On Worship
After obeying the conditions given by the Lord, we must worship Him as he has commanded. Since there is only one church, we must find the right one so that we can continue to please God. His word plainly teaches that it is possible to worship him in vain (Mt. 15:8-9). The acts of worship that we read about in the Bible consist of prayer, singing, giving of our means, teaching and being taught, and eating the Lord’s Supper on a weekly basis (Acts 2:42 ff; Eph. 5:19; 1 Cor. 16:1-2; Acts 20:7; 1 Cor. 11:17-34). We are commanded not to go beyond the doctrine of Christ, and not to participate with those who do, so it is imperative that we find the right church and worship with that body (Gal. 1:8-9; 2 Jn. 9-11).
When a group calling itself the church adds instruments of music to their service or takes the weekly observance of the Lord’s Supper from their service, then on that point they are wrong. They are not the church we read about in the Bible. We must take our Bibles and find the right church which worships God in Spirit and in Truth. (Jn 4:23-24)
It must be remembered that in order to be the right church, it must be right on all points. One church may be right on most points and wrong on a few, and another church wrong on most points and right on a few. Which one is right with God? (Jas. 2:10). The answer would be, both are wrong and need to get in line with God’s Word completely. We don’t please God by being partially right. If we obey a deviated gospel, we are lost. If we worship a deviated doctrine, we are lost. If we teach another gospel, we are accursed. Gal 1:6-9 If we teach another doctrine, we have not God. 2 Jn 9 Each individual church of Christ have self autonomy. Some are right and some are wrong. As individual Christians, we must choose to abide with the ones who are following the gospel and doctrine of Christ, and reject the ones abiding by the doctrines of men.
Conclusion: It is true that there are no perfect local churches because there are no perfect Christians. However, the universal church of Christ is perfect. Thus, the churches of Christ which has the same gospel and same doctrine as its pattern to follow as does the universal church of Christ must be attended. Those which reject this same gospel and doctrine must be avoided.
