Let's take a good honest look at this statement.What I've said to DHK elsewhere becomes apparent at this point in the conversation: Sola Scriptura is not a principle by which unity might be reached for it assures one of his rightness when he's right and it assures him of his rightness when he's wrong, as well.
First, no person or organization, including the RCC or the Baptists can claim infallibility on all things. Perhaps that is what turned you off in the first place.
If the RCC claims infallibility then they are condemned and deluded.
They also go contrary to the Scriptures.
Here is what the Bible says about claiming infallibility:
2 Peter 1:20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
--It is the RCC that claims their own private interpretation that all shall follow. That takes away the duty of others both to study and to draw their own conclusions as per the command in 2Tim.2:15.
Infallibility assumes a position of sinlessness.
1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
1 John 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
If one is never wrong it is the same as saying they have never sinned is it not?
With that admission, it is the same as saying:
that one has deceived themselves, the truth is not in them, they make Christ a liar, and His word is not in them.
To claim infallibility has serious consequences.
We all are fallible. No one is perfect. No two men believe exactly the same on all things.
Sola scriptura allows man, made in the image of God, to study and use the mind and intellect that God has given to man to come to his own conclusions as he believes.
Baptists have always fought for this basic principle for soul liberty, tolerance, or freedom of religion. It is a basic human right--both within and without the churches.
Man was never intended to be a submissive mindless being with no ability to think for him or herself. But that is how the RCC organization is set up. The members of the RCC are not allowed to interpret the Bible. The priest must do it for them. Everything is set out for them. "No thinking allowed."
Look what Paul said here:
(KJV) For there must be also heresies among you, that they which are approved may be made manifest among you.
Now "heresy" had a different meaning 400 years ago. It meant divisive.
Weymouth has a very good translation here:
(WNT) For there must of necessity be differences of opinion among you, in order that it may be plainly seen who are the men of sterling worth among you.
--Obviously there was no "Deposit of Faith" as the Catholics define it, no RCC Catechism, etc. There were differences of opinion. Paul said it was a good thing, not a bad thing. By teaching and comparing scripture to scripture, those "approved" or "men of worth" would be plainly seen among the members.
