History of Catholicism Religion

historia del catolicismo

As a denomination that has been around for centuries, several things can be covered when it comes to the history of the Roman Catholic Church.

Followers of the Catholic Church purport that it was founded by Jesus Christ through his divine teachings. 

The accounts of these teachings are recorded in the New Testament and are mostly explained in the book of Acts, which covers the spread of Christianity in the Roman Empire.

Also, the book of Acts provides details on how Apostle Paul spread Christianity during the early stages of the religion’s growth.

According to traditional doctrine, the Roman Catholic Church came about as a continuation of Christ’s early church that he formed with his Apostles in the 1st century CE.

Like most Christian denominations, the Catholic Church faced a lot of challenges as it spread through the Roman Empire and other parts of the world.

Those who practiced pagan worship in the region were against Catholicism religion and Christianity as a whole, and this made it difficult for most people to join the religion.

However, during the Constantinian dynasty, Emperor Constantine embraced Christianity in 313, allowing denominations like Catholicism to expand throughout the empire.

As the Roman Catholic Church spread, it had a dominant influence in the region and other parts of the world. This made it easy for people to receive the message that the church was preaching.

The Catholic Church became even more influential in Europe after the collapse of the Western Roman Empire, which occurred from 395 AD to 476 AD. Consequently, the pope gained supremacy and influenced the spiritual and political aspects of early societies. 

The growth of papal supremacy created a better relationship between the Catholic Church and the people, thereby causing an astronomic spread of the Catholicism religion.

Currently, the Roman Catholic Church has the largest followership in the world, all thanks to the efforts of early Christians.

The Catholic Church is not only dominant in Europe but is also widely spread in South and North America, not to forget Africa and other parts of the world.


Doctrines of Catholicism Religion


1. The Bible as God’s Word

  • The doctrines that govern Catholicism are scripture-inspired, meaning the adherents believe and do everything in accordance with Bible accounts.
  • Moreover, Catholics consider the Bible to be error-free and is God’s divine word. And like most Christian denominations, Catholics believe that they can understand God’s true nature by reading the scriptures.
  • That being said, the Bible is an important element of worship in Catholicism. And that is exactly why it is used as a reference point during mass or when addressing other spiritual matters.

2. The Holy Trinity

  • The Catholicism religion is one of the denominations that championed the existence of the Holy Trinity
  • According to the Trinity, there is one God, but He is consubstantial and coeternal in the form of three persons as God the Father, Son, and the Holy Spirit.
  • The Trinity is a fundamental doctrine among Catholics as it gives them a better understanding of God’s nature. In addition to this, it provides the adherents with an idea of how they are supposed to view God and all His marvelous creations.

3. Papal Supremacy

  • Adherents of the Roman Catholic Church view the Pope as the vicar of Jesus Christ. As such, the Pope is considered infallible when covering what is written in the scriptures or when talking about church doctrines.
  • The pope is considered one of the most powerful leaders due to his vast influence on Catholics and those who are not part of the denomination.
  • Besides, the pope is at the top of the hierarchy of the Roman Catholic Church, so anything that he says goes, provided that it is supported by the scriptures.

4. The Assumption of Mary

  • This is yet another fundamental doctrine that governs the beliefs of those in the Catholicism religion.
  • Being the mother of Christ, Mary is a central figure not only to Catholics but to Christianity as a whole. 
  • Catholics believe that after her death, Mary was taken into heaven both in the spiritual and physical form. However, Catholics don’t pray to Mary but simply praise and honor her for giving birth to Christ.

5. The Transubstantiation

  • The Catholicism religion teaches that the wine and bread served during the Holy Communion or Eucharist represent the blood and body of Christ Jesus.
  • When celebrating Christ’s last supper with his Apostles, Catholic priests read the words of Jesus Christ from the Bible to the congregants to honor his last moments on earth.

These are just but some of the doctrines that govern the Roman Catholic Church. They are widely covered in the Nicene Creed, a Christian statement of conviction that is spiritually accepted by mainstream Christianity.
