Many people read this post and then misquote it. They actually ignore the data.
Many people quote the statistic that there are more than 30,000 christian denominations. It turns out this is mistaken. There are about 40,000 christian church organisations, three quarters of them independent churches, not denominations, in Africa. The number of denominations is way less, and the number of differences in belief less still.
Please read on to see how I worked all this out.
I was asked recently how many christian denominations there are worldwide. It’s hardly an important question, but some critics of christianity use the number of 30,000 to 40,000 to argue that a true God couldn’t be behind christianity because god would communicate better.
So I thought I’d check it out.
Most references I could find end up quoting the same couple of sources:
- World Christian Encyclopedia (David A. Barrett; Oxford University Press, 1982) apparently estimated almost 21,000 denominations, and the updated World Christian Encyclopedia (Barrett, Kurian, Johnson; Oxford Univ Press, 2nd edition, 2001) estimated at least 33,000. “Denomination” is defined as “an organised christian group within a country”.
- The Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary estimated 34,000 denominations in 2000, rising to an estimated 43,000 in 2012. These numbers have exploded from 1,600 in the year 1900.
These figures are fairly consistent where they can be compared.
What do these estimates mean?
- These “denominations” are defined in terms of being separate organisations, not necessarily separate beliefs. This is a critical difference, not commonly noted by critics.
- The largest component (something like two thirds to three quarters) of these totals are “independent” churches, mostly in Africa. These are not necessarily different in doctrine, but are simply independent organisations.
- These estimates include national branches of the same denomination (e.g. the Lutheran Church of Germany and the Lutheran Church of Australia) as separate organisations in the count.
- There are many churches among the independent churches which would have effectively the same teachings, just different locations, different leaders, etc.
It is thus incorrect to say that these figures indicate more than 40,000 different beliefs. It is impossible to tell how many differences in belief there would be, and probably impossible even to define. But it would certainly be far less than the 43,000 figure.
Differences in belief
- The sources suggest christian denominations can be divided into “6 major ecclesiastico-cultural mega-blocs”: Independents, Protestants, “Marginals”, Orthodox, Roman Catholics and Anglicans.
- Wikipedia lists about 40 major divisions, each of whom might have some variation in belief.
- The degree of difference in belief is hard to describe. For example, most of these denominations would have similar beliefs about major christian doctrines such as God, creation, Jesus, salvation, Holy Spirit, forgiveness, etc, and the differences would mostly be on less essential matters. How much these differences matter is subjective.
The denominations measured in these two reports are not indicators of separate belief, and quoting them as such is a mis-statement of the data. Due to the large number of independent churches, it is impossible to know how much christian belief varies beyond that defined by the 40 or so groups listed in Wikipedia.
My personal view is that christians divide and give themselves denominational-type names too easily. Jesus said his followers should be “one”, and many of these separate organisations are the result of serious divisions. It would be better if we emphasised what we have in common more, and worried less about these divisions.
Nevertheless, critics of christianity have work to do before they can realistically define the degree of division.
