Why is it necessary to write about Roman Catholicism?

It is necessary to write a page on Roman Catholicism because there are significant differences between Protestant and Roman Catholic doctrines. Protestants accuse the Catholics of being unscriptural, and the Catholics state that the Protestants do not have the true faith carried through the centuries by the Catholic Church. On whichever side you fall, the real issue is whether or not the Roman Catholic Church is representing true Christianity.

If you are a Roman Catholic, please understand that this site is not meant to offend you in any way. This site is dedicated to examining the truth, all truth, and comparing it to the Bible. No matter who it is or what group is proclaiming truth, we know that the Bible is the Word of God and that no truth from God will contradict it. I urge you to examine what is here on this site and see if what is being taught here is true. If you do, you will be doing exactly what the Bible commands: to examine all things (1 Thess. 5:21; 1 Pet. 3:15; 2 Tim. 2:15; Acts 17:11; Jude 3). Since the Catholic Church holds the Bible to be the word of God, I am putting Catholic doctrine to the biblical test.

If you are a Protestant, you will probably feel more comfortable browsing these pages since they will, essentially, confront Roman Catholic teachings. It is apparent that the Roman Church has added much to the scope of Christian doctrine that is not revealed in scripture. This is an issue that needs to be addressed. It is vital.

The Protestant Church cites the Bible alone as the source of doctrinal knowledge. The Catholic church, on the other hand, cites the Bible and Tradition. Please consider the following:

" . . . the Church, to whom the transmission and interpretation of Revelation is entrusted, does not derive her certainty about all revealed truths from the holy Scriptures alone.  Both Scripture and Tradition must be accepted and honored with equal sentiments of devotion and reverence."1

Apparently, it is Tradition that is the source of doctrines which are clearly not taught in the Bible, but which the Catholic Church still says are implicit within its text and elucidated through Apostolic Tradition. Some of them are as follows: The Mass, Penance, Veneration of Mary, Purgatory, Indulgences, the Priesthood, the Confessional, the Rosary, Venial and Mortal Sins, and statues in the Church. The issue is whether or not these teachings of the Roman Catholic Church are credible. Do they accurately represent Christianity? Can they be substantiated with the Bible? Do they contradict the Bible?

This site attempts to examine the doctrines of Rome and compare them with the Bible to see if they are supported or contradicted by God's Word. We know that all truth in God's Christian Church comes from Him through the Holy Spirit. It will not, therefore, be contradictory. Let us see what God's written word says and compare it to the Unwritten Word which is the Roman Catholic Church's term for Tradition.
