We may not know it all; but, as much as resides in scripture we do know and have the capacity by the mind of Christ to understand. You're making excuses for ignorance.
Ignorance is bliss and you are basking in it! For three hundred years the Fathers debated what is inspired and what not. You obviously know nothing of the Church history. Yes, the Fathers knew scripture when they saw it, but there were numerous false "Gospels" and manuscripts floating around that had to be separated, and even those that some thought were genuine others thought not -- while others thought of false as acceptable. You really need to learn some facts for a change.
Oh, I'm well aware of the facts. I've been studying comparative religion since the late 80s. I've been debating religion for more than Six years now. And you are still making excuses.
There are 33,000 or more Protestant 'denominations'
Who cares. I'm a Christian. There are 33,000 different ideas about what Catholicism is. Who cares. There is One Christianity with One master - Jesus Christ. We don't all believe with imperfect knowledge, we believe or disbelieve based on what we are taught from scripture or learn from scripture on our own. You apparently haven't learned from scripture. You've learned plenty of philosophy; but, that won't save you or excuse what you accept that is unscriptural. Understand, in the end, you'll be judged based on the Word of God. You can't go before God scratching your head and saying 'sorry God, we have an imperfect knowledge and just can't know you..' You'll wear a God-sized bootprint on your butt as you scream on the way back down. Stop trying to beg excuse here for five seconds and imagine begging excuse before God. And keep in mind the passage where in he states: Romans 1:20 "For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that they are without excuse:" You're without excuse. And what I just did was state it from proper authority.
Excuses? I am merely aware that humans are finite beings. What we know is finite and imperfect. We believe with imperfect knowledge. I don't care how many DDs or PhDs you put behind your name, or how long you studied this or that, you will still know only part of the Truth.
