“Traditions backed up by Scripture...”
All of Catholic traditions are backed up by Scripture; they predated scripture, as a matter of fact. There are scriptural proof texts for all of them. You can go to the apologetics websites yourself rather than asking me to cut and paste.
The defense for Catholic theology is sound and it is IN SCRIPTURE.

No doubt, some FRoman Catholics are squirming in their seats reading your assertions right now. They KNOW that this is not really true that not ALL Catholic theology is "IN Scripture". In fact, IF that was really a true statement, then RCs would not have any problem with the doctrine of sola Scriptura but it is and has been vociferously rejected by the RCC, even though plenty of early church "fathers" state firmly that nothing they preach should be accepted unless it have its basis in sacred Scripture.
What is true about some Catholic doctrine - since it is acknowledged that many traditions have no Scriptural basis - is that the Magesterium doesn't NEED to prove doctrines by Scripture because they assert the church has the authority to declare truth outside of Scripture. From http://beggarsallreformation.blogspot.com/search?q=sacred+tradition, we learn:
The official Roman claims for Tradition are found in statements from the councils of Trent, Vatican I, and Vatican II. Trent states the gospel truth and instruction are contained in the written books and in the unwritten traditions which have been received by the apostles from the mouth of Christ himself, or from the apostles themselves.(6) While Vatican I and II reaffirmed Trent's statements, Vatican II adds,
Sacred Tradition and Sacred Scripture, then are bound closely together, and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing, and move toward the same goal. Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit. And Tradition transmits in its entirety the Word of God which has been entrusted to the apostles by Christ the Lord and the Holy Spirit. It transmits it to the successors of the apostles so that, enlightened by the Spirit of truth, they may faithfully preserve, expound and spread it abroad by their preaching. Thus it comes about that the Church does not draw her certainty about all revealed truths from the holy Scriptures alone. Hence both Scripture and Tradition must be accepted and honored with equal feelings of devotion and reverence.(7)
The defense for Catholic theology is NOT as "sound" as you insist it is or have been led to believe.
