The Historical Reliability of the New Testament

[Randy Carson]

Morbid curiosity...but ah, what's the "historically reliable text" that says the catholic church is infallible.....  

You know this is going to derail my thread, right? 

But okay, I'm going to post two answers...the first is one I wrote years ago as a skeletal response to some Mormons I was chatting with in another forum. I modified it slightly later to encompass the Protestant notion that at some point in history, the Catholic Church "went off the rails" thus opening the door to Protestantism. You won't miss the fact that the arguments are geared toward the implications of doctrines that Protestants would readily agree with but misinterpret.

 I would probably update it for regular use in discussions with atheist (since the Bible is of NO value), but this is a quick reply to your inquiry.

The Infallibility of the Catholic Church Proved from Scripture

 
The following verses suggest that the Catholic Church is prevented from teaching error in matters of faith and morals by God Himself. I provide questions below each verse to illustrate why it is applicable to our understanding of infallibility.

Matthew 16:18
And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it.

Q: If Jesus promised to build his own church and that Church ever fell into doctrinal error, would this mean that a) Jesus was a liar, b) Jesus did not have the power to protect his own church, or c) Jesus was incompetent as a church builder?

Matthew 28:20
And surely I am with you always, to the very end of the age.

Q: If the Church fell into doctrinal error at any time during the 1500 years before the Protestant Reformation, would that suggest that Jesus did not remain with the Church “always”?

John 14:15-16
15"If you love me, you will obey what I command. 16And I will ask the Father, and he will give you another Counselor to be with you forever—

Q: If the Church ever fell into doctrinal error, would that mean that Jesus did not give the Counselor or that the Counselor simply failed to remain with the Church “forever”?

John 14:18
18I will not leave you as orphans; I will come to you.

Q: If the Church ever fell into doctrinal error, would that imply that Jesus actually did leave us as “orphans” during all that time?

John 14:26
26But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.

Q: If the Church fell into error despite this promise, would that mean the Holy Spirit failed to teach the Church “all things” or to remind the Church of the things that Jesus had said to the Apostles?

John 16:13
But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.

Q: Could the Holy Spirit fail to guide the Church into all truth - or allow the Church to fall into error - if Jesus promised otherwise?

Now, consider the following three verses:

1 John 4:4
4You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world.

1 Timothy 3:13
15if I am delayed, you will know how people ought to conduct themselves in God's household, which is the church of the living God, the pillar and foundation of the truth.

Mark 3:27
27In fact, no one can enter a strong man's house and carry off his possessions unless he first ties up the strong man. Then he can rob his house.

Q: Is Satan stronger than Jesus, is the Church the household of God, and can Satan rob the Church of the deposit of truth by “binding” Jesus in any way?


In light of the above, is it possible that the Church fell into doctrinal error? Taken individually, each of these verses creates a problem for those that assert that the Church “went off the rails” at some point in history. Taken as a whole, they portray Christ’s own involvement in building, nurturing and protecting His Church until the end of time. The Catholic Church remains strong and vibrant – not by her own efforts or innate qualities – but because God Himself is leading and guiding her to ensure that “the gates of hell will not overcome it.”

Now, this second article fleshes out the logic a bit more wordily.

Infallibility Explained by Reasoning from the Scriptures

Excerpted from an article by Jeffrey Mirus, PhD
http://www.ewtn.com/faith/teachings/papac2.htm
 
It is clear even from Scripture that Peter had a special commission and special powers from Christ to care for the flock of Christ, to bind and loose, and to confirm his brothers in faith -- indeed he had the very powers of the keys to the Kingdom. Obviously, these powers were essential to the Church as constituted by Christ. And Christ promised to be with the Church always to the end of time, and said that the powers of hell would not prevail against it.
 
Now, clearly Christ knew that Peter would not live until the end of time, so he must have intended that the power he gave to Peter would be carried on until His return. After all, Peter was to feed "my" (Christ's) sheep, and so was serving as the vicar of Christ in Christ's absence. When Peter died, a new vicar would take his place, and so on, until Christ returned to claim his own. The parable of the steward awaiting his Master's return is very much to the point.
 
Just as clearly, Peter's authority also enabled himself (and his successors) to set forth the manner in which their successors would be selected, either by choosing the successor personally before death, or by setting forth some other means -- eventually, election by the college of cardinals.
 
Moroever, if these special and essential powers were to pass out of existence, it would be proof that Christ was no longer with his Church and that the powers of Hell had indeed prevailed. Therefore, again, Christ must have intended successors to Peter.
 
For this reason, we are not at all surprised that subsequent popes claimed to have the Petrine power and that the early Christian community accepted it without question. This authority was exercised by the fourth Pope, Clement, while St. John the Evangelist was still alive. The earliest Christians were in a position to know Christ's will from other sources than Scripture (just as we today, under the guidance of the Church, are able to learn from Tradition).
 
Now we come to the specific question of infallibility, by which the successors of Peter continue to confirm the brethren. Since the successors of Peter have the same Petrine authority, which comes ultimately from Christ, to bind and loose, they have the authority to bind the faithful in matters pertaining to salvation -- that is, in faith or morals. Now, if a Pope could bind the faithful to error, it would be a clear triumph of the powers of Hell, because the entire Church would be bound to follow the error under Christ's own authority. Obviously, this cannot happen.
 
Therefore, the logic of the situation demands that the Petrine power of confirming the brethren must be an infallible power. When the Pope intends by virtue of his supreme authority to teach on a matter of faith and morals to the entire Church, he MUST be protected by the Holy Spirit from error -- else the powers of hell would prevail.
 
Further, it is not a new thing. It was precisely defined at Vatican I in order to clarify what was at that time a confusing issue, but this was by way of stating clearly what Christ's teaching was, not by way of adding anything new. Vatican I therefore carefully enumerated the conditions under which the Pope was in fact infallible -- the same conditions which logic demands, which Scripture suggests, and which tradition shows us in action down through the centuries.
 
When the Pope (1) intends to teach (2) by virtue of his supreme authority (3) on a matter of faith and morals (4) to the whole Church, he is preserved by the Holy Spirit from error. His teaching act is therefore called "infallible" and the teaching which he articulates is termed "irreformable".

Hope that helps.
