1 Corinthians 4.1 Let a man so account of us as of the ministers of Christ and the dispensers of the mysteries (Greek - musterion) of God.
Apparently your "Christianity" excises large chunks fo the Bible. Try doing a search of "musterion" in a Greek New Testament.
The Church is not the appendage to the priesthood; but the minister is the steward of God to the Church. Man shrinks from too close contact with God; hence he willingly puts a priesthood between, and would serve God by deputy. The pagan (like the modern Romanish) priest was rather to conceal than to explain "the mysteries of God."
The minister's office is to "preach" (literally, "proclaim as a herald," Mat 10:27 ) the deep truths of God ("mysteries," heavenly truths, only known by revelation), so far as they have been revealed, and so far as his hearers are disposed to receive them. JOSEPHUS says that the Jewiwhile the pagans concealed from all but the "initiated" few, the mysteries of theirs.

Was Josephus wrong? Is the purpose of the church not to reveal God to men ? Or is it to keep men from the "mysteries" from men?
