Reformed,
I will try to answer your questions to the best of my ability. I think it’s laudable that you are asking the right question and seeking the truth in sincerity of heart. Try not to argue your theological points in light of your theological beliefs, doing that would be tantamount to the a scholar of the law who did not see the Christ right in front of them.
First of all, not one person can give you the full blown Tradition. You can’t sum up 2000+ year (if you count O.T. Traditions) of Divine Revelation.
Second of all, have you attended RCIA classes? These classes will give you the authentic Catholic Tradition in it’s formal context.
Next, the key to understanding Sacred Tradition is to understand Divine Revelation. God has chosen a people (the elect) to follow on his word. In the old covenant, God freely chooses Abraham and makes him a promise. In the new covenant, God chooses His Church as the elect and bride. I have scripture to back this up, but right now I’m too lazy to go look those up.
