You sound like you are describing a game of Telephone! I think you have underestimated the Power of God to watch over His word. Again you are denying the validity of Isaiah 55:11. The Sacred Traditions, consisting of the Word of God transmitted by the Apostles to the Church is preserved infallibly by the Holy Spirit. How can you suggest that the Holy Spirit would allow human failings to contaminate the Word of God?
It is true that a lot has changed. Culture, technology, science, politics. And yes, we can go back to inspired Scripture, but it does not contain all that God wanted us to know. If it did, why did Jesus bother to establish a Church? Was He just entertaining Himself because tiddlywinks had not yet been created? Did He expect the Church to fall to the ground after the Scriptures were penned? This is what you seem to want us to believe.
Although we see references to Mary’s sinless state in Scripture, since people who received their faith whole and entire from the Apostles do not extract doctrines from the text, we are not concerned that all there is to be known may not be recorded specifically in Scripture. The same is true of the Trinity, the hypostatic union, celebration of the Lord’s Day on Sunday (rather than observing the Sabbath), and the table of contents for the Scriptures. All these things, which you seem to accept without question, have come to you through that same sacred tradition. If you cannot trust that Sacred Tradition, on what basis to you not observe the Sabbath?
My dear sir, you have given an excellent example of why the Reformation is still very much before our eyes. Except that the Reformers did still hold to infant baptism, and veneration of Mary, which subsequent children of the Reformation have jettisoned.
This begs the question, tgG. Why are you here at CAF? You say that you are so busy you cannot read all the posts, yet you continue to come here to strive with Catholics. How do you know that the Holy Spirit is not calling you home?
