I am not saying that I have the best arguments to defend Catholicism against Protestantism. Here are some that I found helpful for me as I have interacted with Protestants on this.
Argument 1.
If there were no Catholic Church, there would be no Protestantism.
Now, I suppose that could go either way, but here is why I think it favors Catholicism. It also favors the Orthodox Church, but I prefer Catholic. My ancestors split away from the Western Church, so it seems to me that the logical place for Protestants to return when they want to go home is the Catholic Church. Others have different ethnic backgrounds or they just like Orthodoxy better. They are basically the same Church.
My grandparent’s church on one side was Lutheran. On the other side, various Protestant including Presbyterian, Methodist, and others. The curious thing about my mother’s family was that her grand father was Irish Catholic. No one in the family knew that until he was on his deathbed and called for a priest. That shocked the mostly Methodist family, as you can imagine. Because of strong anti Catholic sentiment where they lived, he thought it more expedient to attend the local Methodist church with his family.
So, here are my arguments. No, I am not a brilliant theologian or scholar - just an Evangelical with many years of experience in full-time Christian work. My weakness in scholarship will be evident, but the arguments have some validity anyway. Fine scholars and Catholic apologists make them much better than I do, of course.
Maybe my process - or journey as many like to say - will be of help to someone else. If nothing more, maybe someone will understand better why a lifelong Evangelical with extensive international ministry experience would become Catholic. Mostly my ministry experience includes the following: 1.) evangelization of children and teacher training 2.) teaching and playing music 3.) opening our home to many needing hospitality. I will refrain for now from giving a more complete resume.
I. Scripture
A. Protestants, - for all their touting of sola scriptura, - are not the ones who gave us the Scriptures. The Catholic Church has very strong arguments showing that it was indeed Catholics who preserved the sacred texts in the first place. You can add the Orthodox Churches to that as well. It was the faithful monks living in monasteries - often in remote places - that carefully copied the texts and preserved them.
There are no such places that Protestants can point to since Protestants do not have monks or even priests in the first place. They rely on all the work that these ancient men of God did for all of Christianity.
Sure, Anglicans have priests, but many of them have also returned to the Catholic Church. Protestantism was forced on England by King Henry VIII. Many never wanted to leave Catholicism in the first place.
B. The Orthodox churches accept the longer canon of Scripture. That is, they have the same canon as is used by Catholics.
"These books—Tobit, Judah, more chapters of Esther and Daniel, the Books of Maccabees, the Book of the Wisdom of Solomon, the Book of Sirach, the Prophecy of Baruch, and the Prayer of Manasseh—are considered by the Orthodox to be fully part of the Old testament because they are part of the longer canon that was accepted from the beginning by the early Church.”
- Canon of Scripture Q&A
C. Protestants are the ones who changed Scripture. How did they do that? By removing books from the canon that both Catholic and Orthodox accept as canonical. On what authority was that done? On the authority of the ones who decided that they had the authority to do so, and nothing more.
There was no ecumenical council called.
D. The Septuagint - which contains what the Orthodox call the longer canon and Catholics call the deuterocanonical books as well as the rest of the Old Testament - was the Scripture used in Jesus’ day. In fact, there are many quotes and references in the NT from what Protestants call the Apocrypha. Catholics call it the deuterocanonical books.
If you don’t believe me, read the deuterocanonical books and see for yourselves. Of course, you have to know the New Testament really well in order to see that. I have been amazed at times when the daily reading for the Catholic Church includes parts of those books.
If you are not very familiar with the New Testament, you can check out this website where the owner has documented many examples of such quotes.
E. The principle of sola scriptura is easily set aside by Protestants when Scripture tends to disagree with their interpretations. The Reformed Christians are especially notorious for ignoring what they call the plain reading of Scripture and going with their traditional interpretations.
Nowhere is this seen more clearly than with Jesus’s words about the Eucharist. What part of “this is my body” is unclear” ?
So, they go with something called sola scriptura, not solo scriptura. In other words, Scripture is really not alone. It has to be understood in light of the Westminster Confession of Faith or the Institutes of the Christian Religion or some other authority.
Exactly. So sola scriptura is not what you think it is. It doesn’t really mean Scripture alone.
It is a game that is played by Protestants - the sola scriptura dodge, I suppose it could be called.
Why not just forget the whole game? Which is what I did.
