One of the most amazing doctrines of Christianity is the doctrine of Perspicuity. That is, you don't have to be a scholar to understand Christianity. If you have access to a Bible, you have everything you need. Or, to put it as Psalm 119:130 does, "The entrance of Your (God's) words gives light; It gives understanding to the simple."
The irony is that foolishness tends to increase with education. This isn't always the case, of course. Education, when used correctly, is a good thing. However, the more a wise man learns, the more he realises he needs to learn, whereas foolish people learn a little bit and think they know it all.
This can be seen all throughout the Bible. Although God does occasionally speak through the educated (e.g. Paul), He more often battles with them. The educated tended to puff themselves up against God, whereas the less educated were often very receptive to Him.
The Pharisees are the obvious example. In their hubris, they called themselves "fathers", because they taught the Scriptures to the less educated. This is why Jesus commanded us to call no man father (Matthew 23:9). Just one verse earlier, He also forbade us to be called teachers or Rabbis, for this same reason.
Two gifts the Lord gives us are the Scriptures and the Holy Spirit. So powerful is the Holy Spirit that John, under His inspiration, tells us that we don't need anyone to teach us (1 John 2:27). The Scriptures are so powerful that they are more authoritative even than genuine messengers from God. In Acts 17:11, for example, we are told that the Jews in Berea were more fair minded than those in Thessalonica, because they searched the Scriptures daily to find out if what Paul was teaching them was true.
Thus, we see that in Christianity, teachers are effectively lower than the students. Ours is not like other religions where the leaders are above reproach, and the faithful must submit to their authority. Rather, a true teacher of the word will always encourage you to test them by it, and may even beg for correction where necessary. Just as an FYI, such is the nature of this ministry. I never want you to read my material and just blindly accept everything I say. Rather, I want you to test what I say against the Scriptures. Believe me when I am correct (though in reality, you wouldn't be believing me, but believing God through me), and reject me when I am not. If possible, correct me.
If any church tells you that you need them to understand Christianity, that is an instant red flag. That is a false teacher who does not want you to test them against the Scriptures because they know they cannot stand that test. Anyone who truly believes they are telling the truth will be confident in their abilities to withstand such a test. As Paul exhorts us under inspiration of God, "test all things, hold on to that which is good" (1 Thessalonians 5:21).
