Is the Catholic faith the true faith?

part 3 (see my pinned thread for parts 1 and 2)
We established in the last 2 parts that:

1) God exists
2) God became man to save us from our sins
3) It would be most fitting if he established a Church

In this thread we will establish that this is the Catholic Church
There are countless evidences of the Catholic Church, but I will advance 4 lines of evidence:

1) The authority of the bishop of Rome
2) The constancy of doctrine
3) The fulfillment of the mission of the Christ
4) Miracles
One of the primary claims that makes Catholicism unique among other Christian denominations is our claim in the preeminent authority of the bishop of Rome. This doctrine is founded on 2 claims:
1) Jesus gave preeminent authority to St. Peter
2) Peter passed this authority to Rome
We see Jesus give preeminent authority to St. Peter when he gives him the keys in Matthew 16. These keys must be understood contextually. One of the key points in the ministry of Jesus is the reestablishment of the kingdom of David.
In the kingdom of David, there was a prime minister, whose authority (as recorded in Isaiah 22) was to open and shut with the key of David. This was only an earthly authority. However, Peter is given the keys to heaven, with authority on heaven and earth.
From the earliest days of the Church, it was recorded that Peter died in Rome, and that his authority was passed on in Rome. This is recorded in both Pope St. Clement (96 AD) and St. Irenaeus (180 AD).

Some will say that they accept that Rome should have a higher authority than other bishops, but not as high as it has become. However, only one Church has a bishop of Rome to begin with.

Now that we have established the authority of Rome, has it always taught the same faith?
It would be too long to detail the countless examples, but all the essential doctrines, such as baptismal regeneration, the real presense of Christ in the eucharist, the authority of Rome, and many other doctrines have been taught consistently over 2 millenia.
These beliefs are well documented in the Church Fathers, the medieval scholastics, and modern theologians. Every Catholic doctrine is well attested to in the early centuries of the Church. The Church Fathers have been heavily translated in English and are free online to read.
Some will object that there has been development. However, this is a good thing. The Church teaches that theology is a science. While the fullness of the faith was revealed by the first century, many great theologians have since come to help us better understand it.
Thus, Catholic doctrine is not a random amalgamation of doctrines, but a well ordered synthesis. All the seemingly arbitrary doctrine of scripture and the Church Fathers were shown by the scholastics to fit together and make perfect sense.
They even showed the consistency of the faith with what could be known by reason. Thus, the Church does not oppose reason, but elevates it by giving us truths that are beyond even the grasp of our reason, as well as correcting suttle errors in our reasoning.
Now what was the purpose of the mission of Christ in the first place? It was to reconcile mankind with God and neighbor. Thus, we should see these actually fulfilled in history. We can see this in the witness of the Church as a whole and the witness of the many saints.
The Church has a whole has been foundational in many areas. It singlehandedly invented the very concepts hospitals and universities, as well as international law, modern science, and many other areas. It also continues to be the largest charity today. Tom Wood’s book is very good
Christ also told the Church to bring the gospel to the whole world. The Catholic Church has done more than any other denomination to bring Christianity to every corner of the earth.
While some allege that this is due to colonialism, missionaries frequently fought against colonial governments to defend the rights of the natives. For example, St. Junipero Serra walked from California to Mexico City to complain to the governor about colonial abuses.
The Church has thousands of canonized saints. These saints show the example of what it means to be transformed by divine grace and made virtuous. There are saints of every walk of life: kings, peasants, missionaries, martyrs, monks, doctors, and everything in between.
Finally, there is the evidence of continuing miracles. For every canonized saint, 2 verified miracles are necessary, Skeptics can even show up to try and debunk the miracles. This means there are thousands of well documented miracles by the saints.
While other Christians have miracles too, none of these miracles are contrary to the Catholic faith. There is a miracle though that uniquely proves Catholicism though: Our Lady of Fatima.
3 children claimed that on October 13, 1917, the Virgin Mary would provide a sign in Fatima, Portugal. Thousands of skeptics showed up to debunk the children. These skeptics reported seeing the sun move in the sky, and the event was well documented even in anti-Catholic media.
The children reported that Mary had revealed 3 secrets to them. One of these was that the Pope consecrated Russia to the Immaculate Heart of Mary. Thus, it requires 2 uniquely Catholic doctrines: the papacy and the immaculate heart of Mary.
Now that we have established the truth of the Catholic faith, what should you do? We’ll deal with this in part 4.

I’m listening to an interview with a scholar who argues that there is no evidence of persecution of Christians in the Roman Empire.

After nearly an hour, she clarifies that her argument is that they were killed for refusing to offer sacrifices to the emperor, not for being Christian…

The absolute state of modern scholarship…
I’m not even exaggerating. Her book is titled “The Myth of Persecution.” Here is her explanation of that “myth”:
Basically “The Romans didn’t kill them for their faith, they killed them because they found their faith annoying.”

How does this woman have a degree from Yale and a position at a prestigious university?

.@redeemed_zoomer Please stop making stuff up about Bonaventure and Scotus. Both affirmed natural theology and thought we worship the same God as Jews and Muslims. Yet you portray them as disagreeing with Thomas in your video.

I will reply with proofs from Scotus, but plenty could be found in Bonaventure as well.Image
It is well known that Scotus thinks the existence of God can be known through natural reason. For example, see Ord. I d. 3 q. 1 n. 5 Image
In Ord III d. 23 q. un. n. 6-7, Scotus gives the example of a Jewish child who even believes in the Trinity and incarnation on account of being taught it, but believes it only on acquired faith and not on infused faith, and so is not saved. Image

A thread on Jewish Catholics 🧵

Throughout every age of the Church, there have been many converts to the Catholic faith from the Jewish people. I want to highlight many notable ones. I will only include those who have passed to the next life. This list is by no means exhaustive. Image
First, we should remember that all the saints of the Old Covenant are Catholic saints. Furthermore, all of the Apostles were Jews. Aside from St. Luke, every other author of scripture was from one of the tribes of Israel. Finally, Our Lord and Our Lady are themselves Jews. Image
Furthermore, the first 15 bishops of Jerusalem were all Jews. This was the center of the Jewish Catholic community, as is recorded in places like Acts 21. After the Bar Kokhba revolt in 135, the Jewish Catholics were scattered and the community seems to have quickly disappeared. Image

In some recent threads, I showed that the biblical requirements for the messiah match better with Jesus than those laid out by the Rambam.

But that was easy mode. Let's see how the prophet Daniel predicted the exact year of the messiah would die to end sin!

A thread🧵 Image
In the book of Daniel, Daniel receives a series of visions of 4 kingdoms. These kingdoms are traditionally identified by Jews and Christians as Babylon, Medo-Persian, Greece, and Rome. Image
According to Daniel 7, one like a Son of Man comes and destroys the fourth kingdom and establishes his own, everlasting kingdom. This is a clear reference to the messiah in 2 Samuel 7.

According to Christians, one of the most clear prophecies of Jesus in the Hebrew Bible is Isaiah 53. However, many Jews dispute that this passage is not about the messiah. Let's take a look at the book of Isaiah to see who is right.

A thread 🧵 Image
In my last thread, I argued that the messiah is central to scripture. He is the promised seed who will undo the curse of Genesis 3

By 2 Samuel this seed has been narrowed down to the line of David. A seed from this line will sit upon the throne "forever"

If you opened 1 Kings for the first time, you would think this king would be Solomon. He builds a house for God's name. However, we see Solomon, and then many kings after him, lapse into grave sin.

Isaiah prophecies during these later kings.

In my last thread, I put forward a response to the Rambam's arguments for why Jesus is not the messiah.

However, I think the divide between Christians and Jews is deeper. We have different conceptions of what a messiah is. So here is a defense of the Christian view.

Thread🧵 Image
Although world peace will come about in the time of the messiah, Jews understand the messiah to be primarily the national leader of the Jews. He will not perform any great miracles or change the nature of things.
However, Christians understand the messiah to heal all the sins of the world and fulfill the very reason for creation. While he comes from the line of David, his national kingship of the Jews is secondary to his universal salvation. Image
