Christians from Which Denomination Have the Most Thorough Knowledge of the Bible?
by Rich Deem


An online Basic Christian Theology Quiz was used to assess whether there are differences in Bible literacy among parishioners of various Christian denominations. The results showed that non-denominational and Baptist believers exhibited significantly higher Bible knowledge than Roman Catholics, Lutherans, and Methodists.


Ninety-three percent of U.S. Americans have a Bible in their home.1 So, we would expect most Americans to be familiar with basic Christian biblical principles, right? However, according to a Gallup poll, only 59% of Americans read the Bible even "occasionally."2 Only 21% read the Bible weekly.2 So, it would not be surprising if the average American had a poor understanding of basic biblical principles. However, many Christians get their Bible teaching through their local church. Denominational churches that teach more from the Bible are more likely to have Bible-educated followers. A Gallup survey showed large differences in church attendance among denominations, with Baptist, non-denominational, Pentecostal and LDS churches securing more attendees.3 Since individual Bible study is sporadic, it seems that those denominations that regularly teach from the Bible and have larger attendance would have parishioners who were more Bible literate. This hypothesis has been tested through an online "Basic Christian Theology Quiz."

Materials and Methods


The "Basic Christian Theology Quiz" has been online since January, 2001. In October, 2010 the quiz was changed from a JavaScript format to the Perl/CGI QuizTest script (Scripts for Educators,, which allowed recording of quiz results. Besides individual results, the software was setup to record the participant's religion and denomination. The Bible quiz consisted of 25 5-possible-answer multiple choice questions related to basic biblical theology (see appendix). For this study, results were accumulated for the time period October 8, 2010 through June 27, 2012.

Participant Recruitment

Participants were recruited online through the website Evidence for God from Science (, a Christian apologetics website. Participant recruitment was accomplished through links scattered mostly throughout the "theology" pages of the website, along with some search engine traffic:

   Others 479
TOTAL 14,838

An average of 9.8 participants per day completed the quiz for a total of 6,051 participants out of 14,838 referrals. The number of Quiz visitors and completed quizzes over the duration of the study are shown in Figure 1.

Site Statistical Analysis

Analysis of site statistics was done using Deep Log Analyzer (



Figure 2 shows the religious demographics of Bible quiz participants. The data shows that the vast majority of quiz takers came from non-denominational churches. In contrast, the majority of the U.S. population attends either Roman Catholic or some form of Baptist church.4 So, all denominations are under-represented in recruited Bible quiz participants.

Although Evidence for God from Science is an international ministry, most quiz participants were recruited from the United States:

Table 2. Bible quiz participants country of origin
Country # Visitors  
United States 9,537   (72%)
United Kingdom (Great Britain) 684   (5%)
Canada 564   (4%)
Philippines 339   (3%)
Australia 300   (2%)
India 251   (2%)
South Africa 133   (1%)
China 100   (1%)
New Zealand 92   (1%)
Germany 74   (1%)
Others (132 other countries) 1,209   (9%)


Figure 3 shows the scoring percentage based upon denomination/religious preference. Since the quiz was designed to be difficult, scoring was spread across a wide range (0-100%), with the average being 61%. As expected, there were significant differences in Bible knowledge across denominations and religious belief. Christian denominations that tend not to emphasize biblical teaching, such as Roman Catholics (45%), Lutherans (53%), and Methodists (52%), scored below the statistical average. Those denominations that do place an emphasis on Bible teaching, such as Baptists (64%, although did not reach statistical significance) and non-denominational churches (65%), scored higher than average. A significant number of atheists and agnostic participants (79) took the Bible quiz. Since, for the most part, members of these groups do not study the Bible, they scored significantly below average (at 46%)—only slightly above Roman Catholics (at 45%).

The distributions of test scores are shown in Figure 4. All distributions are approximately normally distributed.


The hypothesis that certain Christian denominations have better understanding of basic Christian Bible knowledge is confirmed by results of an online Bible quiz. Because of large sample sizes involved in the study, it is unlikely that the result is due to sampling bias. Individuals belonging to Roman Catholic, Lutheran, and Methodist denominations scored significantly lower than the general population. Christians attending non-denominational churches scored significantly higher than average. For the most part, scoring on the quiz was indirectly proportional to the relative church attendance percentages found in the 2006 Gallup survey of church attendance.

Is it possible that the selection method has somehow skewed the demographics such that certain groups have excess numbers of Bible-proficient/nonproficient individuals? The website, Evidence for God from Science tends to attract individuals who are interested in Christian apologetics, making it more likely that those individuals would be more serious about their Bible knowledge. This probably explains why non-denominational believers are highly over-represented among Bible quiz participants. In order to test whether individuals from certain denominations have general deficits or proficiency in knowledge, a more generalized religious knowledge quiz, modeled after the Pew Forum U.S. Religious Knowledge Survey,5 was instituted. The results from this study showed that no particular denomination scored above or below the mean result (Figure 5, p > 0.05). Not only were the results equal across denominations, participants of the Pew Forum quiz scored much higher than those who participated in the Pew Forum U.S. Religious Knowledge Survey (83% correct answers compared to 50% correct answers). Therefore, differences in biblical knowledge among participants of various denominations are probably not due to a deficit in general religious knowledge, but more likely due to a specific defect in knowledge of the Bible.

Knowledge of basic biblical principles has been shown to vary across Christian denominations, with non-denominational and Baptist believers exhibiting significantly higher Bible knowledge than Roman Catholics, Lutherans, and Methodists.
