Can you name any man, from the Bible, who had "formal Theological training"? Can the Holy Spirit not "train" or teach men in the way?
My grandfather was called by God to be a pastor of a little church for years. That small church grew into a fairly good sized one because the Holy Spirit was there. It's easy for man to puff himself up because of "higher education", but in the grand scheme of things... all of your Bible knowledge without charity profiteth nothing. Without charity and humbleness, you will never completely understand the Word of the Almighty God.
Paul didn't have "formal training", yet he was a great teacher lead by the Spirit. Jesus didn't have formal training... nor did Moses, nor did Noah, nor did John the baptist... the list goes on and on. The one thing they did have that I've never seen as evidence in your posts was the Holy Spirit, they walked with the Almighty. They were humble and the fruit of the Spirit was evident in their lives.
Any man who claims to have "head knowledge" and has not "heart knowledge" of the Word of God knows very little. I can have education about the condition of a poor person and consider that I know ALL about their circumstances, but until I humble myself and get into the rut with them (charity), I know very little of their hardships.
In peace and grace,
