I was wondering what elements of Catholic teaching are considered to be infallible. I am confused as to what parts of Catholic teaching are considered to be “formal” and authoritative and which parts are able to be altered and updated over time. Is the Catechism infallible? What other teachings are infallible?
This is what Catholics consider to be infallible teachings, for we profess these divine infallible teachings; From the Nicene Creed reveals what we believe to be infallible teachings of the Church.
I believe in one God,
the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
I believe in one Lord Jesus Christ,
the Only Begotten Son of God,
born of the Father before all ages.
God from God, Light from Light,
true God from true God,
begotten, not made, consubstantial with the Father;
through him all things were made.
For us men and for our salvation
he came down from heaven,
and by the Holy Spirit was incarnate of the Virgin Mary,
and became man.
For our sake he was crucified under Pontius Pilate,
he suffered death and was buried,
and rose again on the third day
in accordance with the Scriptures.
He ascended into heaven
and is seated at the right hand of the Father.
He will come again in glory
to judge the living and the dead
and his kingdom will have no end.
I believe in the Holy Spirit, the Lord, the giver of life,
who proceeds from the Father and the Son,
who with the Father and the Son is adored and glorified,
who has spoken through the prophets.
I believe in one, holy, catholic and apostolic Church.
I confess one Baptism for the forgiveness of sins
and I look forward to the resurrection of the dead
and the life of the world to come. Amen.
All developed doctrine point to these apostolic infallible teachings.
Doctrines are revealed infallibly with the divine keys Jesus gives to the Church to bind and loose upon the whole earth, in order to protect, defend and develop a deeper understanding to all ages, what is professed and believed from the Nicene Creed, was handed down to us, infallibly by Jesus and His Apostles by Oral Sacred Tradition and Sacred Scripture.
The Developed or clarified Doctrinal Infallible teachings of Jesus Christ, do not move from our Apostolic unchanged Profession of faith. An infallible teaching of the Church does not and cannot conflict with sacred Apostolic Tradition and Sacred Scripture, nor can a Church doctrine ever be altered or subject to change.
Development of a divine revelation is not altered or changed, these are Rock. But knowledge and understanding is developed and made more clear to the changes of human understanding of human knowledge and languages.
For example; The Word Trinity is not revealed in Sacred Scripture. But the True substance of the Trinity is revealed by both Sacred Oral and Sacred Scripture. See Matthew 28:19. Yet the Trinity came under attack four hundred years after the resurrection of Jesus Christ. Thus the Catholic Church counseled and made the Trinity binding (Keys) upon the whole of Christendom.
Because the Catholic Church made the Trinity a doctrine later in time, does not mean that it is a new revelation or new teachings. Trinity protects the apostolic faith, that Jesus is fully God, fully Human. We profess this unchanged apostolic faith within the Nicene Creed above.
Peace be with you
