Hi, guys —

I'm a Protestant Christian. I'm a member of the Church of Christ which is a non-denominational church. We have no central headquarters or president. The head of the church is none other than Jesus Christ Himself. (Ephesians 1:22-23) Each congregation of the churches of Christ is autonomous and it is the Word of God that unites us into One Faith. (Ephesians 4:3-6) We follow the teachings of Jesus Christ and his holy Apostles and not the teachings of man.

  • I'm not trying to insult you whatsoever but I just want know what Biblical evidence do you use to back up what the Catholic Church teaches and practice?

I have a great respect for the (RCC) Roman Catholic Church and I have considered converting but, putting it nicely, my mother already frowns on my sister being a Baptist so I resist those considerations to go further.

Hi Alden,

You'll need to narrow your question. To answer it would require volumes and volumes of books. You might like to browse the answers we've given to previous inquirers or first peruse the tract section at:

If you want, we can start at 1 Timothy 3:15, which says that the Church (not the bible) is the pillar and foundation of the truth, or, 2 Thessalonians 2:15 which says to hold fast to the traditions which you received, whether by word of mouth or by letter. Or Jude 3, which says that the faith was once for all handed on to the saints.

All three of these verses — and these are only three of many — refute the idea that we should only believe that which is found in Scripture. A careful reading of the New Testament will show that it was largely an oral faith — when the authors uses words such as hear, which they use far more often than read, they indicate that the faith is an oral one. (cf. Matthew 7:24-26, Matthew 10:14, Matthew 10:27, Matthew 13:20, Matthew 18:17, Mark 4:16-23) There are just way too many more to count right now.

Do a search in our Knowledge Base for "sola scriptura" or tradition. Even the verse that most Protestants appeal to prove sola scriptura (The doctrine that we should rely on Scripture alone for our doctrine) in 2 Timothy 3:16 is preceded by an interesting verse that says,

"But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it ..." (2 Timothy 3:14)

which means that not only is the faith orally transmitted, it is also important to consider who transmitted it. In other words, you don't just believe any yahoo on the street or just read Scripture and come up with your own conclusions. You need to believe someone who has Apostolic Authority . . . someone who can trace his teachings back to the Apostles.

I recommend a book, if you're really curious:

It is written to Catholics; it's a little sassy. A more irenic book, targeted to non-Catholics, is:

If you want to continue to discuss Sola Scriptura that is fine or if you have a specific question about a specific teaching after consulting our Knowledge Base, feel free to reply-All and ask it.


Mike replied:

Hi Alden,

Thanks for the question.

Beside Eric's very good advice you may be interested in my Scripture passages web page:

What this page won't do is give you the context and understand of how each passage
supports Catholic teachings. That's where Eric's book suggestions come in.

I hope this helps,


Alden replied:

OK guys,

What Biblical evidence do you have to support:

  • the Eucharist, and
  • Apostolic Succession
  • Original Sin, and
  • unmarried priests.

Again have the greatest respect for the RCC and especially Pope Francis.


Mike replied:

Hi, Alden —

I am a little confused. Didn't you see those biblical references on my Scripture Passages page:

The most important Biblical passages which no Protestant should discount are the ones on:

The Bible was never meant to be a Catechism or a book of beliefs. The Bible is a liturgical, Catholic book — written by Catholics and their ancestors, for Catholics, for use in the Catholic Mass.

Because of your open-mindedness to the faith you may be interested in my other web site:

This web site consists totally of quotes from the very first Christians. You can compare what they said from the first to eighth century on an array of topics and compare it to what the Catechism of the Catholic Church says today.

Decide for yourself if they are similar.

I hope this helps,
