We begin our profession of faith by saying: "I believe". Before expounding the Church's faith, as confessed in the Creed, celebrated in the liturgy, and lived in observance of God's commandments and in prayer, we must first ask what "to believe" means. Faith is man's response to God, who reveals himself and gives himself to man, at the same time bringing man a superabundant light as he searches for the ultimate meaning of his life.
Humans are by nature and vocation, religious beings. Coming from God, going toward God, man lives a fully human life only if he freely lives by his bond with God. Man is made to live in communion with God in whom he finds happiness: "When I am completely united to you, there will be no more sorrow or trials; entirely full of your, my life will be complete" (St Augustine, Confessions 10, 28, 39: PL 32, 795).
When he listens to the message of creation and to the voice of conscience, man can arrive at certainty about the existence of God, the cause and end of everything. The Church teaches that the one true God, our Creator and Lord, can be known with certainty from his works, by the natural light of human reason (cf. Vatican Council II, can. 2, § 1: DS 3026).
We really can name God, starting from the manifold perfections of his creatures, which are likenesses of the infinitely perfect God, even if our limited language cannot exhaust the mystery. "Without the Creator, the creature vanishes" (GS 36). This is the reason why believers know that the love of Christ urges them to bring the light of the living God to those who do not know him or who reject him.
I believe in one God, the Father almighty,
maker of heaven and earth,
of all things visible and invisible.
And 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.
And 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.
And 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.
