In discussing the Catholic Church with Protestant anti-CatholicsI've noticed they often have selective amnesia — they simply don't address the biblical verses strongly supporting the Catholic view. When I bring these verses to their attention they typically ignore them and present other verses instead. We should consider all verses of the Bible, not just those supporting our view.
Ye see then how that by works a man is justified, and not by faith only. (James 2:24)
And the scripture was fulfilled which saith, Abraham believed God, and it was imputed unto him for righteousness: and he was called the Friend of God. (James 2:23)
Thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth. (1 Timothy 3:15)
The church is the pillar and foundation of the truth, not the Bible. What can be more clear?
I should note it is common for Protestant anti-Catholicsto misrepresent the Catholic view regarding the Bible. The Catholic Church teaches the Bible is the inspired, inerrant, infallible Word of God. The difficulty arises in interpreting it truthfully.

Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. (2 Thessalonians 2:15)
Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us. (2 Thessalonians 3:6)
For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do. (Mark 7:8)
Jesus gives an example — washing pots. This kind of thing is hardly a doctrinal matter with the Catholic Church yet Jesus objects because the religious leaders made such things into a salvation issue.
Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. (Colossians 2:8)
Paul, the writer of this verse, also wrote the passages in 2 Thessalonians (noted above) commanding Christians to hold to the Traditions and walk in the Tradition. Surely he considers these Traditions and the "tradition of men" as two very different things.
