The basic tenets of Catholicism are the fundamental beliefs of the Roman Catholic Church.

Are you looking for a quick & simple guide to basic Catholicism? Here’s a primer on Catholic Church doctrine — the essential tenets of Catholicism.

The scope of these tenets of Catholicism

The four categories of the full content of the Catholics church:

  • Basic beliefs (the faith itself)
  • How to live (morality)
  • How Catholics worship (liturgy)
  • Prayer

This page and its related articles covers the first of those points — the tenets of Catholicism are the basics beliefs of the faith.

Other articles here at beginningCatholic.com cover the other three categories of the Catholic faith, as well as provide more information that’s important to the beginning Catholic. You can also look to other reliable guides for learning the faith — see my suggestions at the end of this article.

The Catechism of the Catholic Church

The Catechism of the Catholic Church contains a full description of the tenets of Catholicism — the essential and basic beliefs in Catholicism. It defines the points of unity for Catholics. (Click here to read the tenets of Catholicism in the Vatican’s online Catechism.)Every Catholic should have a copy of the Catechism. You may not read it cover to cover, but you’ll want to use it as a reference for learning about your faith. (It is pretty readable, though, and a lot of ordinary Catholics do read it to get a full understanding of the tenets of Catholicism.)

There are more readable sources available.

At the end of this article is a list of other reliable guides to the Catholic faith. I strongly encourage you to read some of them!

  • Alan Schreck’s The Essential Catholic Catechism is my top recommendation for learning the basic beliefs in Catholicism.
  • Leo Trese’s The Faith Explained is a very close second to Schreck’s book. In fact, you should read both if you can do so: they are very different and complement each other quite well.
  • I’ve added detailed reviews of these books at the end of this article. Check them out!

Creeds: Summary of the faith

From its earliest days, the Church used brief summaries to describe an outline of its most essential beliefs.

These summaries are called “creeds”, from the Latin credo, meaning “I believe.” They are also called “professions of faith,” since they summarize the faith that Christians profess.

The Catholic Church uses two very old creeds regularly as a part of its liturgy and other prayers. There are a number of other Catholic creeds as well.

The older Apostles Creed is brief and simple. It is the ancient baptismal symbol of the Church at Rome. (See Catechism, 194.)

The longer Catholic Nicene Creed contains some additional language explaining our belief in the Trinity.

Another ancient & traditional creed is commonly called the Athanasian Creed, since it was originally attributed to St. Athanasius, who died in 373 A.D. (This creed is no longer officially attributed to him.) It is also called the Quicumque vult, after its first words in Latin. This beautiful creed contains a detailed meditation on the nature of the Trinity.

RCIA : The Process of becoming a Catholics

The process is called the Rite of Christian Initiation of Adults (RCIA), so you may see that referenced. By adults, it includes anyone over about 8 years of age, but there are usually different groups for older children, teens, and adults.

For someone converting to Christianity, you will enter the Catholic Church by baptism at the Easter Vigil, the night before Easter Sunday. Normally the preparation process should take a minimum of one full year, sometimes longer or a little shorter depending on how long you have been thinking about this, what your understanding of Christianity is, etc. During this process you are known as a catechumen – one who is learning about the faith.

For someone who is already Christian, a variation is available. It is generally faster, and can be as short as a few weeks or as long as a year, depending on your tradition, background, etc. Normally you would be brought into full communion sometimes during the Easter season, but it could be any time of the year, really. During this process you are a candidate for full communion.

Strictly speaking, “conversion” is only for non-Christians becoming Christian. For candidates, as you are already Christian, you do not “convert”. But we don’t really have a handy name for the move.\

Whether there are any costs associated with the program is up to the individual parish, but most in my experience consider it a part of their core ministry and do not charge anything. Even if they do, the fee is never very large, and if it is in itself a barrier, would be waived.
