There are many things I don't know. What I don't know, I don't know. And what I don't know, I would ask questions.
For example. I am comfortable at reading scriptures, then I do with customs, rituals and dogma on the inner working of the church that are not found in the scriptures.
But even when reading scriptures, I am far more interested in the stories - the narratives - than I am with reading laws, poems, wisdom, etc.
And as for prophecies and signs, it often based on interpretations. In some cases, especially with the "messianic" prophecies, you would have totally different interpretations than that of the Jews. Jews have different concept of the Garden of Eden story, for example. Another example, is that the Jews view Satan as a servant of God, with specific duties, while you (and most other Christians) view Satan as God's enemy. Jews don't in any rebellion in heaven, because angels don't have free will.
And I surely don't that much about church history. There are too many different sects, too many different doctrines and interpretations. It's too complicated and downright boring.
Christians sometimes don't even agree among themselves. Some view the creation narrative and the Flood story as being historical and literally true, but others don't, because they see these stories in Genesis as allegories, probably they are more aware that it neither historical nor scientifically possible.
The difference between you and I, is that I don't have excess baggage of faith or belief that come with reading and analyzing the scriptures. I'd question everything.
But I think you approach things differently from me. You would probably take everything written at its face value. You are more likely take your scriptures for granted, because you are most likely to believe whatever you read on faith or whatever clergy have taught you, rather than look for evidences to prove it is true.
If I am wrong with your ability, then I'd often sincere apologies for misjudging you.
