Well how very interesting. First you claimed"A contradiction occurs when two (or more) different statements on a topic cannot both be true at the same time and in the same sense. For instance, let's look at the statements "I am walking my dog," and "I am not walking my dog." Both statements cannot both be true at the same time and in the same way. They are mutually exclusive. However, the following is not a contradiction: "Bob saw two people get out of the 1967 black Camaro," and "Frank saw three people get out of the 1967 black Camaro." These statements are not mutually exclusive because both statements can be true at the same time. Bob may have been at an angle where he was only able to see two people, where Frank could have been at a different angle where he was able to see three people. Both statements can be true at the same time and in the same sense without excluding the other."https://carm.org/what-is-a-contradiction
The accounts in the gospels of Jesus' death and resurrection are reliable. Any apparent contradictions suggested by skeptics can be reasonably explained. Actually, the fact that there are differing, yet complimentary details throughout the gospels that give a harmonious presentation of Jesus as the promised Messiah and Savior is one reason to believe that the accounts were based on real events.
When I then pointed out to you that in fact the conditions of a contradiction you defined were indeed there, you conveniently forgot about that explanation and clearly googled to find the currently accepted apologist explanation that although both the Bible claims both the passage in Luke and the passage in John to be stating the last words of Jesus, they were actually mistaken and were only reporting the last words of Jesus that the person Luke and the person John personally heard.For there to be a contradiction one of the passages would need to specifically state that it recorded the “only” last words Jesus spoke at his death, and no other words were spoken at the time of his death. Then, if there was a discrepancy between two accounts, we would have reason to believe there was a contradiction. However, the gospels do not make that claim.
Also very interesting, for two reasons. First, you personally were clearly unaware of this contradiction until I pointed it out to you, and didn't have a reasonable explanation for it. Like most evangelicals you're shockingly ignorant of your own holy book you attempt to hit the rest of the world over the head with. But not to let that stop you, just google a reason and go with that, no need to think critically on your own right? And of course don't admit that the reason you previously gave, the one we can all clearly see in writing right on this thread, was 100% wrong. Definitely what Jesus would do, am I right?
The second issue is much more confounding for the likes of your beliefs. Let's be clear, you're an evangelical and you believe the Bible is 100% true and to be taken entirely literally. Except this one time, in which case you decide, despite nothing in the verses to indicate it, that when God tells us in Luke 23:46 " “Father, into Your hands I commit My spirit.” Having said this, He breathed His last.” that's not really literally what happened, that's just what a man named Luke heard. Or alternately when God told us in John 19:30 ""When he had received the drink, Jesus said, “It is finished.” With that, he bowed his head and gave up his spirit.", that's not actually what happened, it's just what John heard. That's a somewhat reasonable explanation...as long as you don't believe the Bible is the 100% unerringly true word of God to be taken completely literally. So let's agree, you'll jettison the assertion that anything written in Luke or John is the 100% unerringly true word of God to be taken literally. After all you just told me it in fact was just a retelling of what these two men heard and they both couldn't have been right that two completely different things were Jesus' last words, your definition of a contradiction. At which point I'll stop pointing it out as a contradiction. Or you agree it's a contradiction. You can't have it both ways, sorry.
And maybe, while you're at it, start approaching everything in life with the scientific method which assumes that your current knowledge is just what you know up to now, you could very well be wrong, and you're open to evidence of that. Including your religion. Or stop trying to justify your religion using "evidence", which as I've shown is clearly impossible. Again, you can't have it both ways, it simply doesn't work. There's nothing wrong with religion, but fundamentalist religion is simply completely and utterly indefensible from an "evidence" perspective.
