But why study the Catechism if it does not include everything, why not just study the scriptures?
We have to remember a couple of things:
1. Christ started and ran his ministry without the bible. He taught verbally.
2. The Apostles continued Christ's ministry and teachings without a bible.
3. Everything the early Christians practiced and believed was handed down by word of mouth and letters between the Apostles and the Churches.
4. People began collecting those writings, some were valid some were not and thus several councils had to be called to decide which letters and accounts of Jesus' life and ministry were correct and which were flawed.
5. Those books combined with the Jewish Cannon of the Old Testament became our bible.
6. During this period until our present time the Church continues to teach verbally and from the collection of letters and accounts of Jesus life and minstry.
7. The verbal teachings, which are God-Inspired, led and protected by the Holy Spirit is called Sacred Tradition and the which are God-Inspired, God Breathed letters are Sacred Scripture.
8. Sacred Scripture was never designed to be a complete "How to Be a Christian" maunal OR all the teachings handed down over 2000 years would be detailed in the bible.
9. No where in the bible does it claim that Scripture is all we need. In fact there are several passages that remind the listeners that they need to hold fast to the teachings given to them by the Apostles - either spoken to them or in writing.
10. Catholics hold Sacred Tradition and Sacred Scripture on equal planes.
This is a high-level overview but its enough to dispell some of the misconceptions about the Catholic Churchs teachings.
The Catechism.....it gives us an exaplaination of why we are Catholic and how we function as Christian Community.
