Fellow Catholis, I would not assume that Protestants, especially Evangelical Protestants, have not studied the entire Bible. That would be a tactical error on your part that will eventually get you into trouble during a conversation with a Protestant.
I grew up Evangelical Protestant (Conference Baptist).
By the time I was 18, I had read the entire Bible (Protestant version, minus the Deuterocanonical books) through several times, and by the time I became Catholic, I had not only read the entire Bible dozens of times, but I had studied every book in either a private Bible study (on my own, using a text book), or in a group Bible study.
I even studied the books of the Minor Prophets.
Evangelical Protestant denominations, as well as many other types of Protestant churches, strongly encourage their Christians to READ THE BIBLE everyday, and they provide the opportunities and tools to accomplish this.
Most Evangelical Protestants strive to have a daily “Quiet Time,” or “Morning Watch” or “Daily Devotions,” during which they read the Bible, study it, often memorize it, and pray about it.
Most Evangelical Protestants also attend at least one, and often several Bible studies.
And many Evangelical Protestants get involved in a teaching ministry in which they learn even more Bible. They may not be the “teacher,” but they are involved in the ministry in some way that exposes them to Bible teaching.
In addition, Evangelical Protestants are strongly encouraged to read the entire Bible through. Many Evangelical Protestants read the Bible through over and over again, and they will show you their well-used and tattered paper "guide that they use to know which Books and Chapters they are supposed to read on any given day. Some read the Bible through chronologically, and others read it in the order in which it is printed.
It’s not true that Protestants ignore or give less importance to the Old Testament. Think about it–when you start reading the Bible, you start with Genesis 1:1–“In the beginning…” That’s Old Testament. Most Protestants understand the need to have a good understanding of the Old Testament because that’s where Jesus came from–the Jews. And many Protestants love the Psalms and Proverbs.
As for whether reading the entire Bible is “church policy” or not–probably not, at least in Evangelical Protestant churches.
Many of the mainline denominations follow the same schedule of reading that Catholics follow; I know that the Methodists do. But not Evangelical Protestants. Many of their worship services are “topical” or “needs-based.” The pastor may do a series of sermons about “marriage” or “raising children” or “how to overcome addictions.” The Bible is used in the sermons, but the sermon is about the topic, not about the Bible.
But even if it’s not official church policy, remember that Evangelical Protestant churches give their people a plethora of opportunities to study the ENTIRE Bible–notice I said “study.” To me, although it’s admirable that the Catholic Church reads the entire Bible (or close enough) in the Mass over a period of three years, I’m not convinced that most Catholics “STUDY” those readings outside of the Mass (I’ll admit, I don’t). I’m not even convinced that all the Catholics sitting in the Mass even LISTEN to the readings with a focused mind.
Also, in the not-too-distant past, some of the Evangelical Protestant denominations DID get their members through the entire Bible. It happened in Sunday school. When I was in 2nd grade, I started attending Sunday school (my mother kept us home from church and taught us at home until we arrived at the Age of Accountability). We received a Sunday School book that started in the Book of Genesis. (Apparently the 1st graders were considered too young for this kind of “book work.”)
Every quarter, we finished with our book and got a new book. Each book covered a book or two (or more) of the Bible. By the time we were in 8th grade, we had covered the ENTIRE OLD Testament, in great detail. We had to bring our books home and do the lessons (which meant reading the Bible chapters) and bring them back, and we also had to memorize various portions of Scripture.
Interestingly, I was in the last class (H.S. Class of 1975) that did Sunday School this way. After I finished 8th grade, the Conference Baptists changed the way they did children’s Sunday School, and started producing Sunday school books that were “modern” and “relevant” and “topic-based.” The children started learning about “love” and “peace” and “Jesus, our Friend.”
So you see, fellow Catholics, the Protestants went through a “Vatican II” of their own! I personally think that this type of Sunday school was a disaster, as it produced a generation of people who knew very little of the Bible unless they studied it on their own. But it sure did attract a lot of people to the Evangelical churches, because the children weren’t bored in Sunday school like they were in those old “stodgy” churches that were still using workbooks and listening to lectures instead of “rapping together.”
Anyway, my point is, do not make assumptions about Protestants when it comes to the Bible.
