After a cursory reading of two texts that seemingly contradict each other, many New Testament critics simply say the Bible has errors. Their logic usually goes like this: “Mark said one thing, Matthew said another. Both can’t be right. Therefore, the Bible has errors and you’re foolish to trust it.”
But it’s not that simple. Different authors use different methods and different words to write about the same thing. Some NT authors spoke more generally, some more precisely, but it doesn’t mean they erred or contradicted one another. Craig Blomberg wrote on this quite well in his essay, “A Constructive Traditional Response to New Testament Criticism.” In this essay, Blomberg goes through a handful of seemingly contradictory NT texts and reasonably explains how they might be harmonized. At the end of the article, he basically says that even if his explanations are wrong, the point is that there are plausible solutions to seeming contradictions:
“…When one has examined a large number of the apparent contradictions in Scripture and time and again discovered plausible solutions – at times even more than one plausible solution – it is only natural to reach a point where one gives the text the benefit of the doubt on the rare occasions of confronting seemingly more intractable problems. These are the kinds of replies that are important to give a professor who asks a student, whether Bart Ehrman or anyone else, ‘Why not just admit that Mark [or any other scriptural author] made an error?’
I very much agree. I’ve had it in my own experience when I thought two texts seemed to be contradictory. I didn’t know what to think, so I studied the texts and read other authors’ comments on them. Indeed, I found various reasonable explanations for the seeming contradictions. I’m at the point now that when I see something in the Bible that seems to be contradictory, I believe the weakness is in my own mind and reasoning, and I give the text the benefit of the doubt. And, of course, I believe that “the Lord’s word is flawless” (Psalm 18:30 NIV). My mind, however, is not!
