A brief answer: Since the Bible is sufficient, why do we need catechisms and creeds?

Ephesians 4

11 And He Himself gave some to be apostles, some prophets, some evangelists, and some pastors and teachers, 12 for the equipping of the saints for the work of ministry, for the edifying of the body of Christ, 13 till we all come to the unity of the faith and of the knowledge of the Son of God, to a perfect man, to the measure of the stature of the fullness of Christ; 14 that we should no longer be children, tossed to and fro and carried about with every wind of doctrine, by the trickery of men, in the cunning craftiness of deceitful plotting, 15 but, speaking the truth in love, may grow up in all things into Him who is the head—Christ— 16 from whom the whole body, joined and knit together by what every joint supplies, according to the effective working by which every part does its share, causes growth of the body for the edifying of itself in love.

John Woodbridge, Research Professor, Trinity Evangelical Divinity School, answers the question “If Scripture is sufficient, why do we need catechisms?” related to his talk “Sola Scriptura: Worldview Formation, Renewing the Church, and Evangelism,” 2017 European Leadership Forum.

Essay Question



Catholic apologists claim that Protestants and Evangelicals have so many ‘sects’ because we read the Bible on our own without a teaching authority; that this has produced tens of thousands of denominations; and that this is a sign of God’s judgment upon Protestantism.

What do you think?

If you disagree, how would you respond to Catholic apologists?


Here are a few responses from Dr. Joe Mizzi of justforcatholics.orgJust for Catholics is “an evangelical ministry dedicated to Roman Catholics who desire to know how to be saved.” (I added links within Dr. Mizzi’s short article, and an excerpt that follows it.)

30,000 Protestant Denominations?

Question: If one thing is clear, it’s that there is one, single, visible Church that Jesus founded. This multitude of competing, conflicting denominations is no sign of God’s work; therefore, it must be the work of the Evil One. Somewhere in the midst of these 30,000 denominations, there is one true church, and the rest are in sin and rebellion.

Answer: The “thousands-of-denominations” argument is very often employed to prove all sorts of things. Here are some citations from letters received from other Catholics:

How can all these denominations claim to follow the Bible yet all come to different conclusions? How can I possibly know which one of those above teach the truth when they can’t even agree on what the Bible says? The Bible alone has created so much havoc in this world.

If there is only one Church, why are there so many Protestant denominations? Possibly many thousands throughout the world, as compared to only one Catholic Church? I do see it as a sign of God’s judgment that there are close to 30,000 Protestant denominations.

The Bible alone can be dangerous. In fact, the Bible alone IS dangerous. Look at Protestantism: 100,000 different interpretation of the Bible, 100,000 contradictions, 100,000 different denominations claiming to have the key.

Peter said that no prophecy of the Scripture is for private interpretation. This is why you have 30,000 different Protestant denominations that all believe differently from one another. This alone should give you a clue that Protestantism is not the true Church of Jesus Christ.

So, the existence of many Protestant denominations supposedly proves that the Sola Scriptura is dangerous, that we should not try to understand the Bible for ourselves, that the church of Rome is the one true church, and of course, all the other churches are false.

Elsewhere I have written on the significance of the heterogeneity among Christians. (See That They May Be One and Disagreement among Protestants). Here I simply want to make one important addition, namely, that the allegation so often repeated by Catholic apologists that there are 20,000 to 30,000 Protestant denominations is simply FALSE . . . not to mention the double standard employed, for the Roman Church is not exactly united. There are untold factions and divisions, and diverse understanding of doctrine within Catholic groups and by different Catholic theologians and individuals.

In an article entitled “30,000 Protestant Denominations?”, Evangelical apologist Eric Svendsen exposes the falsehood of this fabrication. Briefly:

Svendsen shows that the source of this figure is the World Christian Encyclopedia (David A. Barrett; Oxford University Press, 1982).

Barrett cites a figure of 20,780 denominations. However not all of them are Protestants. According to Barrett, Protestants account for 8,196 (and incidentally, Roman Catholics account for 223).

However, even this figure of eight thousand Protestant denominations is misleading, for Barrett defines “distinct denominations” as any group that might have a slightly different emphasis than another group. The distinction is made on the basis of jurisdiction, rather than differing beliefs and practices.

Barrett breaks down the Protestant bloc into twenty-one major “traditions” which are much closer to what we usually mean by the word “denominations.” It is interesting that Roman Catholics are subdivided into sixteen such “traditions.”

Svendsen concludes, “In short, Roman Catholic apologists have hurriedly, carelessly – and, as a result, irresponsibly – glanced at Barrett’s work, found a large number (22,189), and arrived at all sorts of absurdities that Barrett never concluded.”

Dr. Mizzi offers more to counter the claim of Catholic apologists that Protestantism and Evangelicalism are hopelessly fractured, and that this is a judgment of God upon our rebellion, in his article “That They May Be One!” (cited above). In this excerpt he describes factions and sources of authority for Catholicism and Christianity:

Christian denominations do not even begin to rival the diversity between the various groups, movements, societies and orders within the Catholic Church. The spectrum ranges from the cloister nuns and Trappist monks (who spend all their time in silence), through the Masonic-like Catenians and Opus Dei, Traditional Catholics, Liberal Catholics, the Neocatechumens, Catholic Charismatics, Evangelical Catholics and so on. They all fall under the wide umbrella of Catholicism, of course, but the differences between them are just as real, and even wider than between Christian denominations. Someone will protest that this is “diversity within unity” and that all these groups are Catholics and united under the leadership of the Pope. Well then, by the same token, despite their diversity, the many denominations are all Christian and united under the headship of Christ.
