A clear guide, in nine steps, to understanding why the Catholic faith is not a human invention, but a gift received and faithfully guarded from the beginning.
✦ ✦ ✦
1 God Created Everything with a Purpose
God created everything that exists. Nothing was made by chance: everything was arranged with wisdom and oriented toward Him, to manifest His goodness, beauty, and perfection.
Within creation, human beings occupy a unique place. Unlike animals, they possess reason and freedom. Therefore, they can know God, love Him, and serve Him consciously.
This natural relationship between God and man is called natural religion. It does not depend on books or special teachings: it springs from human nature itself.
2 A Happiness Greater Than the Natural
God was not content with offering man a limited happiness. He wished to share with him something infinitely greater: His own life and eternal happiness.
This destiny is so lofty that man could not discover it by himself. Therefore, natural religion was not enough: it was necessary for God Himself to speak and teach directly.
True religion does not arise from human effort, but from Revelation.
3 A Revelation Throughout History
From the beginning, God revealed His truth to the first men, starting with Adam. Those patriarchs lived for many years and could easily transmit the teachings they had received.
Later, God chose a specific people to safeguard the revelation until the coming of Jesus Christ. Christ did not destroy what had been revealed: He brought it to its fullness, and entrusted this complete teaching to the Church.
Religions that do not proceed from this revelation are human creations. Some preserve fragments of truth, but mixed with errors.
4 Divisions Within the Church
Throughout time, painful ruptures have occurred. It is helpful to distinguish them clearly:
⚠️ Heretics
Those who rejected fundamental teachings of the faith and preferred to follow their own ideas.
⚠️ Schismatics
Those who, out of pride or desire for power, broke unity with the Pope and the bishops.
In contrast, the Catholic who listens to the Church, accepts its teaching, and lives according to God’s law, walks securely toward his eternal destiny. The more one knows the faith, the more one understands that it is profoundly reasonable and true.
5 Transmission: Living and Written
God willed that religion be transmitted primarily from person to person: elders teaching the younger, without altering the content received.
Over time, He inspired certain authors to put part of this teaching into writing. These writings form the Holy Scripture, or Bible.
📜 Old Testament
Books written before the coming of Jesus Christ.
✝️ New Testament
Books written after Christ.
6 What Does “Testament” or “Covenant” Mean?
“Testament” here means Covenant: an agreement that God makes with men to save them, on the condition that they believe in Him and obey His commandments.
God made this covenant first with Adam and Noah, then with Abraham and his descendants, and later with the people guided by Moses. All that covenant pointed to a Savior who was to come.
With the coming of Jesus Christ, God established a New Covenant open to all. Those who believe in Christ, receive Baptism, and live according to His teaching, form part of it.
Jesus personally taught His apostles, and they preached first by word of mouth. Later, some wrote, but not everything was put into writing.
7 Sacred Tradition
Not everything that God revealed is found only in the Bible. There is also Tradition: the teaching transmitted orally from the apostles and faithfully preserved by the Church.
Tradition is also the word of God and a firm foundation of the Christian faith.
8 The Church, Guardian of Revelation
Jesus Christ entrusted both the Bible and Tradition to the Catholic Church. She is tasked with preserving, interpreting, and correctly teaching divine revelation.
🕊️ Discern
Determines which books form part of the Bible.
📖 Interpret
Explains the authentic meaning of Scripture.
⚖️ Resolve
Clarifies doubts regarding faith and morals.
🛡️ Protect
Defends the faithful from harmful errors.
9 The Pope and the Bishops
This task corresponds to the teaching Church, formed by the bishops united with the Pope, the successor of Saint Peter.
When the Pope teaches solemnly on faith or morals as the shepherd of the entire Church, he enjoys a special protection from God to avoid teaching error. Furthermore, he exercises supreme authority in the governance of the Church.
The Catholic faith rests on this trusting obedience to the Church and to the Pope, through whom God continues to guide His people.
✝
A Faith Received, Preserved, and Transmitted
The Catholic religion is not a human idea nor just another opinion. It is the Revelation of God, kept alive in Scripture, Tradition, and the Magisterium.
He who listens to the Church, listens to Christ; and he who listens to Christ, walks securely toward eternal life.
