What is the rest of the Revealed word and to whom and when was it revealed???
Incredible some of the silly conclusions folks can come to about the Bereans.
Sometimes it seems like the terminal obtuseness has become a passionate addiction.
Your denial aside, the Holy Traditions of the Church comprise a lot of it. Were all that is necessary containable in a Book God would have repeated the Mosaic process and sent the Gospel on Stone Tablets. Instead He sent His Son to establish a Church.
Ah, and there is the rub. According to the CCC Revelation is complete.
66 "The Christian economy, therefore, since it is the new and definitive Covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ." Yet even if Revelation is already complete, it has not been made completely explicit; it remains for Christian faith gradually to grasp its full significance over the course of the centuries.
Of course the standard disclaimer applies. 'Revelation is complete but we don't yet "understand" it fully.' That's where the Magisterium comes in.
When you are dealing with the Catholic Church remember this: There is no teaching of the RCC which is so clear it cannot be denied, modified, or re-interpreted as required.
