What Do Catholics Believe In?
Our core belifefs as Catholics were formulated into the Nicene Creed from the two ecumenical councils of 325 AD in Nicea and 381 AD in Constantinople. It is also known as the Niceno-Constanople Creed and usually recited at every Sunday Mass. The Apostles' Creed of 325 AD is somewhat shorter, and is sometimes used at Sunday Mass as well as devotionals such as the rosary.
The Nicene Creed
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.
I believe in God,
the Father almighty,
Creator of heaven and earth,
and in Jesus Christ, his only Son, our Lord,
who was conceived by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
was crucified, died and was buried;
he descended into hell;
on the third day he rose again from the dead;
he ascended into heaven,
and is seated at the right hand of God the Father almighty;
from there he will come to judge the living and the dead.
I believe in the Holy Spirit,
the holy catholic Church,
the communion of saints,
the forgiveness of sins,
the resurrection of the body,
and life everlasting.
Amen.
We also believe in the Ten Commandments of the Old Testament, given to Moses directly by God on Mount Sinai, as detailed in Exodus 20:1-17 and Deuteronomy 5:6-21. Unfortunately, they were not numbered but this is the traditional Catholic decalogue:
1. I am the LORD your God: you shall not have strange Gods before me.
2. You shall not take the name of the LORD your God in vain.
3. Remember to keep holy the LORD'S Day.
4. Honor your father and your mother.
5. You shall not kill.
6. You shall not commit adultery.
7. You shall not steal.
8. You shall not bear false witness against your neighbor.
9. You shall not covet your neighbor's wife.
10. You shall not covet your neighbor's goods.
We believe that our Catholic faith is lived through the Precepts of the Church:
The first precept (“You shall attend Mass on Sundays and holy days of obligation.") requires the faithful to participate in the Eucharistic celebration when the Christian community gathers together on the day commemorating the Resurrection of the Lord.
The second precept (“You shall confess your sins at least once a year.") ensures preparation for the Eucharist by the reception of the sacrament of reconciliation, which continues Baptism's work of conversion and forgiveness.
The third precept (“You shall humbly receive your Creator in Holy Communion at least during the Easter season.") guarantees as a minimum the reception of the Lord's Body and Blood in connection with the Paschal feasts, the origin and center of the Christian liturgy.
The fourth precept (“You shall keep holy the holy days of obligation.") completes the Sunday observance by participation in the principal liturgical feasts which honor the mysteries of the Lord, the Virgin Mary, and the saints.
The fifth precept (“You shall observe the prescribed days of fasting and abstinence.") ensures the times of ascesis and penance which prepare us for the liturgical feasts; they help us acquire mastery over our instincts and freedom of heart.
The faithful also have the duty of providing for the material needs of the Church, each according to his abilities.
