Sorry, Mr Rogers, I see no point in continuing this. You ask me, “what theological doctrine is required knowledge for salvation?” That is not the point. The Judge of what constitutes true faith is God, because He is the one who give it. (John 6:44; Ephesians 2:4-10) So, that is a matter God reserves strictly to Himself.
That said, there is the question of what is true about God and man? God’s word speaks to just such things. One cannot deny something clearly taught in the Scriptures without danger. That should be obvious from Jesus’ discussions with the Pharisee, Sadducees, Herodians, and other individuals. So, there is such a thing as truth regarding God and man. That truth can be confessed by one who believes. That is what gave the early church courage to formulate the Apostles Creed, not in an attempt to replace the Word of God, which is not possible, but to confess it. (Romans 10:8-11)
“You ask me, “what theological doctrine is required knowledge for salvation?” That is not the point.”
Actually...it IS the point of this thread and the article that spawned it.
And if someone has a theological question, I’ll point him to the Word of God, not creeds drawn up by philosopher-priests.
If you feel qualified to discuss the details of the Trinity and how Jesus relates to the Father and the Holy Spirit, please feel free to write something to clarify it for those of us who are more likely to add it as number 5 on the list:
Three things are beyond me;
four I can’t understand:
the way of an eagle in the sky,
the way of a snake on a rock,
the way of a ship at sea,
and the way of a man with a young woman. - Proverbs 30
