Ok. My ideas are coming from:
In the CCC there is a heading entitled “The Apostolic Tradition” that has underneath it info about how Sacred Scripture and Tradition is how Revelation comes to us.
CCC 78 says:
Through Tradition, “the Church, in her doctrine, life and worship, perpetuates and transmits to every generation all that she herself is, all that she believes.”
Pope Benedict XVI repeats that saying:
The Church transmits all that she is and believes, she hands it down through worship, life and doctrine.
So it is that Tradition is the living Gospel, proclaimed by the Apostles in its integrity on the basis of the fullness of their unique and unrepeatable experience: through their activity the faith is communicated to others, even down to us, until the end of the world. Tradition, therefore, is the history of the Spirit who acts in the Church’s history through the mediation of the Apostles and their successors, in faithful continuity with the experience of the origins.
So all that the Church believes is handed down through Tradition, according to the above. Wouldn’t that mean Revelation since that is everything that the Church believes?
