In any case, "varieties of truth" do not exist--except as mental constructs.
In reality, there is only truth and falsehood.
I don't disagree, but I think you're still missing the point. In reality, it's not always that simple to determine what is true or false. We don't know all of the truths about the universe, correct? Even the Bible indicates we do not have all of the answers. In Physics, there are some cases where we can only conceptualize that which is likely true, but we have no way of physically proving it.
Christianity is no different. You can prove Jesus existed, but how do you prove he's the son of God? How do you prove the Holy Spirit? How do you prove salvation? How do you move past the conceptualization stage to prove something is true? It's not always possible.
And when faith is all you've got, how did you get there?
Because truth is actualized, right? And *You* can describe that which is true, which was actualized in *you* after you received the Holy Spirit. You might describe a miraculous change you had overnight or an incredible feeling like being in love when you felt God's spirit poured into you. It's tangible to you because you feel it and it confirms concepts *you* read in the Bible, *but* what about the people that haven't experienced God? People that have head knowledge (or faith in concepts that may or may not be true), but do not have the heart knowledge (of God) or experience to say for certain.
If someone doesn't experience God in a tangible way, what do you say then? I think that's what this thread is all about; our varieties of truth that don't fit the *worldly* definition of truth. According to your statement (above), I'm going to throw this question at ya in hopes you'll humor me and answer...
If God's existence is X and X is true, and truth is actualized, then what specifically did you see (or experience)?
