And which manifests what Rome really believes.
Yea, a man may say, Thou hast faith, and I have works: shew me thy faith without thy works, and I will shew thee my faith by my works. (James 2:18)
And Catholics are far more liberal than those who most strongly hold to the supremacy of Scripture as literally being the word of God.
That's because Catholics are taught the Catechism (man's word) rather than the Bible (God's Word). When your belief system is based on man's word it loses it's strength over God's Word which is Absolute. The Catechism of the Catholic Church, paragraph 82, reads:
. . . 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.
