:The Christian teaching that '''scripture does not contradict itself''', that it is '''illicit and wrong''' to interpret it that way, is not ''explicitly'' found in any written text of the Bible, but it is an ''implicit'' part of apostolic oral tradition ([https://www.biblegateway.com/verse/en/2Thessalonians%202%3A15 2 Thessalonians 2:15]).
:There are many competent verse-by-verse biblical commentaries available in print and online which deal with internal consistency of the Bible regarding particular passages that appear to contradict or to be contradicted by other passages. Most of them offer traditional Christian understandings of how apparent contradictions are in reality only superficial misinterpretations of readings based on a lack of sufficient knowledge, in-depth ''extra-biblical'' knowledge, [[Hermeneutics]], knowledge which is not provided by the Bible itself as a whole, but which provides means to discern ''the true [[Historical-critical method (Higher criticism)#The literal sense of scripture|literal sense of scripture]]''. They ably demonstrate that these apparent apparently contradictory texts are in fact verses and passages known to experts in [[Hermeneutics|biblical criticism]] to be reconcilable and resolved without any contradiction, primarily because within the context of the whole teaching of the Bible there is actually no real conflict or contradiction of meaning between them. This is part of the profoundly consoling spiritual work of mercy called "counselling the doubtful" (see [[Corporal and spiritual works of mercy]]). [https://www.biblegateway.com/passage/?search=James+5%3A19-20&version=RSVCE James 5:19-20].
:But not all biblical commentators offer individual explicit commentary on particular difficulties of particular verses and texts which might or might not appear to be contradictory, but only indirectly touch on them, or simply pass over them in silence without specifically addressing the particular issue the inquiring reader might wish to find resolved or examined.
