Shoot. For just a minute there I thought you were going to say "Scripture is not always crystal clear. That is on purpose so that we may know for certain we are to also rely on the teaching Magisterium of the Universal Apostolic Church for clarification and continuity down through the ages."
My bad.
Nah. No need for teaching Magisterium when we have the ONE intercessor between God and man, the Lord Jesus Christ; and the Holy Spirit who would guide us in all things.
