The passage in Hosea is as clear as day; if you believe in the integrity of the Bible, then you accept that God's people die for lack of knowledge.
My answer is: I believe in the integrity of the Pope not the Bible.
1) Does the Pope deny this passage in Hosea? Has any Pope said specifically that knowledge leads to death?
2) Knowledge of God's Law is what helps you to follow God's Law responsibly, so how can that knowledge lead to death?
3) Why must Man have interpreters and go-betweens, authorities other than self and "saviors"?4a) If Christ is not a name, then how can the Pope be the representative of Christ?
4b) If God resides within you, then how can the Pope be the representative of God?
5) Why is the Vatican not a party to The Hague Apostille Convention?
6) If Emmanuel set up a Church, why did he not talk about it explicitly again and again?
