Hi,
This is from Gotquestions.org–you may not agree with what they say but it gives you an answer to your question.
Why are there so many Christian denominations?
Question: “Why are there so many Christian denominations?”
Answer: To answer this question, we must first differentiate between 1) denominations within the body of Christ and 2) non-Christian cults and false religions. Presbyterians and Lutherans are Christian denominations; Mormons and Jehovah’s Witnesses are “Christian” cults; Islam and Shintoism are entirely separate religions.
The rise of denominations within the Christian faith can be traced back to the Protestant Reformation, the movement to “reform” the Roman Catholic church during the 16th century, out of which four major divisions or traditions of Protestantism would emerge: Lutheran, Reformed, Anabaptist, and Anglican. From these four, other denominations grew over the centuries. The Lutheran denomination was named after Martin Luther and was based on his teachings. The Methodists got their name because their founder, John Wesley, was famous for coming up with “methods” for spiritual growth. Presbyterians are named for their view on church leadership—the Greek word for elder is presbyteros. Baptists got their name because they have always emphasized the importance of baptism. Each denomination has a slightly different doctrine or emphasis from the others, such as: the method of baptism; the availability of Lord’s supper to all or just to those whose testimonies can be verified by church leaders; the sovereignty of God vs. free will in the matter of salvation; the future of Israel and the church; the role works play in salvation; pretribulation vs. post-tribulation rapture; the existence of the “sign” gifts in the modern era, and the list could go on and on. The point of these divisions is never Christ as Lord and Savior, but rather honest differences of opinion by godly, albeit flawed, people seeking to honor God and retain doctrinal purity according to their consciences and their understanding of His Word.
Denominations today are many and varied. The original “mainline” denominations mentioned above have spawned numerous offshoots such as Assemblies of God, Christian and Missionary Alliance, Nazarenes, Evangelical Free, independent Bible churches, and others. Some denominations emphasize slight doctrinal differences, but more often they simply offer different styles of worship to fit the differing tastes and preferences of Christians. But make no mistake: we, as believers, must be of one mind on the essentials of the faith, but beyond that there is great deal of latitude in how a Christian should worship in a corporate setting. This latitude is what causes so many different “flavors” of Christianity. The Presbyterian Church of Mbale, Uganda, has a style of worship much different from the Presbyterian Church of Denver, but their doctrinal stand is the same. Diversity is a good thing, but disunity is not. If two churches disagree doctrinally, debate and dialogue over the Word may be called for. This type of “iron sharpening iron” (Proverbs 27:17) is beneficial to all. If they disagree on style and form, however, it is fine for them to remain separate. This separation, though, does not lift the responsibility Christians have to love one another (1 John 4:11-12) and ultimately be united as one in Christ (John 17:21-22).
When looking for a church, the believer should start with its Statement of Faith. What that church believes and practices should be in line with the doctrines of faith as outlined by the Bible. What we should be seeking is a body of believers where the Gospel of Christ is preached, the authority of the Bible is the governing truth, the sufficiency of Scripture is affirmed, where we can grow in our relationships with the Lord, where we can minister to the body with our spiritual gifts, spreading the Gospel and glorifying God. Church is important and all believers need to belong to a body that fits the above criteria. We need relationships that can only be found in the body of believers, we need the support that only the church can offer, and we need to serve God in community as well as individually.
