In my last post, I wrote a little about the idea of Divine Revelation. As Catholics, we are privileged to be members of Christ's own church, instituted directly by Him. As members of His body the Church, we have the fullness of the faith in Christ, and the fullness of His Divine Revelation.
One thing you might notice as you study the Faith is that there are many repeating patterns (often called "Types" in religious literature) - each referring back to a fundamental truth about God. One of these types is the prevalence of the number three - not just a collection of three objects, but rather a grouping of three objects that are deeply, intimately connected with each other. The model for this is of course the Holy Trinity. God's revelation is also given to mankind in three profoundly related ways. Each of these methods of revelation depends upon and is revealed and explained by the other two. None can stand by themselves, and when people try to take one of the three methods of revelation and stand it up by itself, the result is inevitably not God's plan.
The three methods God chose to reveal Himself to mankind are Sacred Scripture, Sacred Tradition, and Magisterial Teaching. I will take a post to explain each of these methods of revelation more fully. But at this point, it's enough to understand that they are all related - Sacred Scripture is the Divine Word of God, Sacred Tradition explains the fullness of that Word in the life of God's people, and Magisterial Teaching explains how to read an understand the realities of Sacred Scripture and Sacred tradition with the mind of the Church - which is the mind of Christ.
