What is truth? said jesting Pilate, and would not stay for an answer.
─ Francis Bacon, 'On Truth'
Dear Creationists
My own view is that truth is conformity with reality. This, often called the 'correspondence' view, means that if you want to know whether a particular statement is true or not, you check how accurately its report corresponds to objective reality. Thus truth can in principle be objectively verified ─ a wholly admirable quality, surely you agree, for any claim of truth to have.
You must use this definition of truth at least part of the time, even if just to know that it's true it's daytime, you're in Kamloops, those are Bikkios on the supermarket shelf, and so on.
But then you add a wholly different concept of 'truth' ─ that the bible is inerrant and therefore all its factual statements are necessarily 'true'.
What truth test did you carry out on the bible to determine that it's inerrant?
Let me show you the big picture first.
You need to first understand what humans can do and can't. Humans are basically blocked from the direct access of both the past and future. It is a kind of delusion (as a result of being brainwashed by education) to think that evidence can lead us to the past efficiently while it's not. As an individual, you can't even remember what you yourself did today but a month (or a year ago). If you can't recall what you did or said efficiently, it means that on that particular day, we have 7 billion humans lost their memory. If you did only one thing or said only one speech, we have 7 billion odd cases per day which can hardly be evidenced. To put it another way, if you can't provide the evidence of your own deed/speeches on a daily basis, nor can the 7 billion humans. We thus have billions after billions of human actions/speeches can never be evidenced in our past. There's how the availability of evidence comes scarcely and rarely.
For the same reason (of lacking access to both past and future), humans seldom rely on evidence to get to a truth, a truth virtually of any kind.
Category of truths:
1) a scientific truth
May be to your surprise, humans in majority seldom rely on evidence to get to a scientific truth. That's why among the 100% humans (virtually all humans in modern societies) who know for a fact that black holes exist, 99.99% of them don't have the evidence!
Humans almost exclusively employ faith in a "middle man" (literally his credibility) as the eye witness to get to a truth. In the black hole case, we rely on the "middle man" our cosmo scientists as the eye witnesses for us to believe them with faith to get to such a truth. It is so because we believe that our scientists are maintaining a direct contact with the truth, and they are deemed to be credible for us to put faith in them to get to the truth. We (99.99% humans) don't examine the evidence of black holes ourselves. The cosmo scientists will do the job for us, and for us to put our faith in to get to the truth.
2) present occurrence
We rely on putting faith in our media to get to a truth occurring around the world on a daily basis. It is so because our media made up of reporters and journalists are believed to be maintaining a direct contact with the eye witnesses, and they are deemed credible for us to put our faith in to get to the truth. We (99.99%) humans don't examine evidence behind each piece of news.
We can't however examine a scientific truth and any present occurrence if we wish to. This is due to the nature of these two category of truths. A scientific truth can be repeated infinitive number of times for us to do our speculation. While a present occurrence may (or may not) leave trails for us to do our speculation.
3) historical occurrence
We rely on putting faith in what have written by historians to get to such a kind of truth. The historians are not necessarily credible, especially in the case of ancient history. This is so because it's out of humans' capability to access the past to confirm their credibility. Sometimes and in front of ancient history, if we choose to reject it, say due to lack of tracked credibility of the historians, it only means we won't have that part of history at all. Under most circumstance we only loosely check the credibility of the authors and will accept its legitimacy simply because we don't have an option!
History can hardly be evidenced. Even the videos of WWII are not evidence strictly speaking. They are part of the human witnessing process, as what we trust with faith is not the videos themselves but the credibility of those behind the videos. We watched them from credible media channels such as National Geographic for us to deem them credible. We could have more videos of UFO, they are however not deemed as truth due to the lack of the credibility. If one day they are broadcast by NASA (a credible agent) we can thus deem them as a truth!
Archaeology on the other hand is about trails left (usually by a fluke) by mass human activities such as war scenes. It's not for the deeds and speeches of individual historical figures. Even when archaeology is taken into account, it's yet another form of human witnessing as 99.99% humans don't dig up in archaeology sites. It's the "middle man" our archaeologists who do the job for us to believe with faith.
4) future occurrence
It's cut from our direct access more completely. The only way left for us to reach the future is by putting faith in the "middle man". If this "middle man" is a direct eye witness of the truth, or he's a direct witness of God (if God exists). You can examine into the credibility of this "middle man" to make your own decision on whether to put faith in or not. Anyhow, putting faith remains the only way to reach the whole category of this kind of truth!
The truth of a religion (assume there's a truth for the sake of argument), is a mixture of 3) and 4). It's a "history" plus an advocate about the future. The different between the "history" of a religion and human history is that human history are the claimed recordings/testimonies of human deeds/speeches which are lying within our comprehension and understanding. The "history" of a religion however is the claimed recordings/testimonies of God's deeds, which are thus not necessarily lying within humans' comprehension and understanding.
Nevertheless, shall there be any truth out there the only possible means for humans to reach such a truth is through putting faith in the "middle man". Unless the god behind chooses to show up in front of all mankind. If the god has a good reason (you may examine to see if the reason provided by the religion is good enough) to hide behind, putting faith remains the only way for humans to reach such a truth.
The "good reason" for the Christianity God to hide behind is that all mankind has a covenant for them to be saved by faith. So if God shows up to everyone, it means all mankind cannot be saved by this covenant. If on the other hand, He doesn't show up to any humans at all then no humans even know of the existence of such a covenant. The only way which works is for God to show up in front of the chosen eye-witnesses (God's prophets and apostles) and for them to write down the "history" of religion, then for the rest of mankind to believe with faith!
