Dear Ginger2,
Cordial greetings.
The fundamental issue in the debate between Rome and the churches of the Reformation is the whole question of authority. Protestants are heirs of the Reformation principle* sola *scriptura, because for them the final authority is the written word of God.
Part of the reasoning behind sola scriptura is the belief that the bible clear and easy for all to understand. However, if Sacred Scripture is indeed straightforward and sufficient, then one must ask why there is a multiplicity of Christians groupings; whatever else may said, Protestantism does seem to have a pathological tendency to divide and fragment. You state that “all true Christians believe in the same basic doctrines which are found in the Holy Scriptures and summarized in the Apostle’s Creed”. This is often and casually stated, but when scrutinzed, it collapses under its own weight. No doubt, you would concur with C.S. Lewis that there is such a thing as “mere Christianity” and that whilst real Christians agree on the basics (“the faith once delivered unto the saints” S. Jude 3), they may disagree on so called second order issues. Unfortunately, when one actually examines what the different denominations teach, one discovers that they not only disagree on non-essential matters - such as, for example, whether ladies ought to wear hats to church or whether one should be baptized immersion or sprinkling the forehead - they also disagree on fundamental or central issues; is baptism necessary for salvation, does it or does it not regenerate; is grace indefectible? How does one understand Holy Communion?; what is the role of good works in a man’s salvation? etc. It is easy to say that Scripture is essentially clear, but experience just does not bear it out because all the myriads of Protestant sects, and individuals within those sects, make their appeal to the same bible to make their conflicting viewpoints. To put it quite simply multiple denominations equal multiple interpretations of the bible.
Now the Catholic would contend that this state of affairs is highly unsatisfactory and reveals that something is seriously amiss within the Protestant groupings. The clear and certain truth that does emerge is that an objective, historical and universal interpretative authority is required in order to correctly ascertain God’s truth. It is only the Catholic Church, through the Magisterium, that provides such an unerring authority. Clearly it is wholly inadequate to say that the Holy Spirit is the authoritative interpreter of Sacred Scripture, since all the multitude of Protestant sects claim the Holy Spirit’s work in their midst, and yet the all disagree, otherwise they would not be separate from one another. Thus was the Holy Spirit wrong?; did he lead some of them into the truth, whilst misleading others? In point of fact the Holy Spirit was only given within the context of the community of faith, the “One Holy, Catholic and Apostolic Church” established by Jesus Christ upon St. Peter. It is only through the Catholic Church that the Holy Spirit can work authentically and most fully. Hence it is only the Church which can most authentically interpret Scripture because it and it alone “…is the Church of the living God, the pillar and bulwark of the truth” (I Tim. 3: 15).
