On consistency between Biblical authors


I was explaining to my wife the other night that whenever I encounter a difficult passage in the Bible, I try to look for related information from the same writer. I don’t immediately jump over to passages in other books of the Bible, pitting one passage against another and letting them duke it out to see who wins. This kind of Bible bashing is, in my opinion, a fundamentally flawed approach and should not be employed by anyone who holds to the principles of perspicuity and inerrancy of God’s word. Instead, I try to understand the difficult passage in its own context, and by context I mean moving in concentric circles from the paragraph to the chapter to the book and then finally to other books by the same writer.

In our brief discussion, my wife agreed with me about context being important, but she found it curious that I would say that I look at statements by the same author and try to avoid other authors until I have a greater understanding of what that one author really meant. I’ve been approaching scripture this way for a while almost without thinking about it and without ever expressing or explaining it to anyone else, and her curiosity about it set in motion some introspection and self-reflection about why I do it. These comments are an attempt to set into words my thought process.

Why do I stay within single authors?

From the world’s perspective, the Bible was written by several individual men. From a Christian worldview, the various scripture books all had one author, namely God, notwithstanding they were written as God inspired those individual men.

If it can be shown that any Biblical author contradicts himself (is not internally consistent within his own writings) then we have really serious problems. Either (1) that author was of lesser intelligence and incapable of articulating cogent and consistent arguments or (2) that author was insane and actually concurrently believed contradictory truth claims, (3) that author changed his mind at some time or (4) at least some or all the documents claimed to be by that author are of dubious authorship and were therefore mistakenly included among the canon.

If it can be shown that the several Biblical authors are each internally consistent, but that they contradict each other, then we can conclude the Bible was written by intelligent but uninspired men who held to cogent and consistent but nevertheless contradictory and competing worldviews. It then becomes a contest as to which one of these authors’ systems of theology is inspired (and thus true) and which are wrong, or if they are all wrong together.

If it can be shown that each Biblical author is internally consistent and is furthermore externally consistent with all other Biblical authors, in other words, that the Bible taken as a whole is internally consistent, then that is possible cause for believing that God authored the scriptures. Considered another way, a necessary condition (but not a sufficient condition) for accepting the Bible as God-inspired is being able to show that the whole Bible is internally consistent.

It is in consideration of the above three “ifs” (the above three paragraphs) that I pay very careful attention to the various authors to make sure they are consistent within their own writings and also with the other authors. If one passage in the Bible seems to contradict the rest of the Bible theologically, I first look for instances from the same author where he is consistent with the rest of the scriptures. Then I consider why he may seem to be contradicting himself in the one passage in question. I try to consider that one author in a vacuum and interact with only his writings before I begin to look outside his writings.

Some working examples

So, for instance, when I look at a difficult passage for perseverance of the saints like Hebrews 6:4-6, I don’t immediately jump over to the best related verses by other authors in other books of the Bible (like John 6:37-40 or John 10:28-29), but I stay right where I am and notice Hebrews 6:9-12, where the author clarifies what he really meant in Hebrews 6:4-6 by stating that, “though we speak in this way,” he is confident that his audience won’t really fall away from faith. Moving further out, but staying with the same author[a], I find Hebrews 7:25; Hebrews 10:14; Hebrews 10:36-39; Hebrews 12:2 and Hebrews 13:5. Clearly the author of Hebrews positively affirms the doctrine of perseverance of the saints.

Another good example is a difficult passage for limited atonement, 1 John 2:2. Compare and contrast that to the almost word-for-word passage John 11:51-52. The parallel statement by the same author helps to clarify the author’s intended meaning. Additionally, passages like John 6:38-39; John 10:11; John 10:14-16; John 13:1; John 15:13; John 17:1-2, 9; 1 John 3:16 and Revelation 5:9 help to establish that John did indeed hold to the doctrine of limited atonement.

Not just for difficult passages

I should mention that this doesn’t apply only to difficult passages. For instance, as John Piper recently pointed out[b], 1 and 2 John are the best commentary you’ll ever find on Jesus’ new commandment in John 13:34-35.

A corollary to this whole idea is not only looking for consistency within authors but looking for consensus among several authors. For instance, in Sunday School at Jordan Presbyterian Church this morning, Pastor Reid found evidence for the historicity of the universal deluge by surveying various Old and New Testament authors. The author of 1 Chronicles includes Noah in Abraham’s genealogy (1 Chronicles 1:4) and Luke includes him in Jesus’ genealogy (Luke 3:36), so they both evidently believed Noah was a real person. Furthermore, Isaiah, Jesus (attested by both Matthew and Luke), the author of Hebrews and Peter all treat the flood as though it was a real historical event (See Isaiah 54:9; Matthew 24:37-39; Luke 17:26-27; Hebrews 11:7; 1 Peter 3:20 and 1 Peter 2:5). Whether you realize it or not, if you allegorize the flood then you are calling into question the credibility of all these Biblical figures.

Conclusion

So I hope I’ve helped you see why paying attention to authorship is a huge part of my hermeneutic—my way of learning from and interpreting the Bible. Realizing how the Old Testament prophecies of Jesus are so amazingly fulfilled in the New Testament was one of the things that made me recognize the authenticity of the Bible in the first place. Realizing further that the Bible was written by multiple authors and yet they are all consistent in what they believed and taught has really helped to solidify that belief for me. I hope I’ve encouraged you to look at the Bible in a different way as you consider the various authors and how they support each other.

  1. It may be important to note here that the writer of Hebrews is anonymous. Hebrews was widely attributed to Paul in the early centuries of Christendom, but in recent years faithful Christians have questioned authorship since the epistle doesn’t contain Paul’s usual greeting and benediction, and has a markedly different style. Some have speculated that Barnabas, Luke, Apollos or Priscilla wrote the book, but ultimately we are left with an unknown. So, to consider writings by the author of Hebrews, I could look to the other writings of Luke if I had any reason to feel confident about that possibility, but ultimately I’m forced to stay within the book of Hebrews.

    Supposed contradictions are not always contradictions. Seeking out their supposed contradictions are a great way to gain greater insight into the scriptures. For a rational thinker, a contradiction in two ideas doesn’t mean that both ideas are false, but it provides an opportunity to find a deeper understanding of the ideas such that the contradiction disappears. Someday we will find that deeper understanding in quantum mechanics and relativity.

    With all due respect to this excellent article by Joey, I still do not see how one word of this theory can be applied across select portions of Moses’ writings to the Christian faiths, for instance. The issue of concubine ownership, for instance, and/or apparent episodes of mass rape and genocide, whatever horror across those select ones applicable to the OT writings, cannot be applied to the person of Jesus Christ, and/or the Holy Spirit.

    I remain convinced to this day that despite many, many precious hearted Christian pastors and theologians having tried to help me make sense of my amateur study of the Bible, the best advise I was ever told came from a kind elder soul when she told me across such simplicity, “The Old Testament was written for the Jewish persons-we’re the Gentiles…(Don’t read a word of it).”

    Whereby the assumption remains at the personal level that I was not called as a single child in the way each of you have that anchor for the Body across pastoral and theological positions, I’m not so certain that this little soul’s remarks wouldn’t have been the very best I’ve ever been told in life from a fellow Christian.
