Faith is a personal act - the free response of the human person to the initiative of God who reveals Himself. But faith is not an isolated act. The believer has received faith from others and should hand it on to others. Each believer is a link in a great chain of believers.
We do not believe in formulas but in those realities they express. At the same time, we approach these realities with the help of formulations of the faith which permit us to express the faith, hand it on to others, to celebrate it in community, to assimilate it and live it more and more.
The Nicene Creed is the faith of the Church confessed by bishops in council and in the liturgical assembly of believers.
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.
