Tips for New Catholics

• Don’t worry if you don’t know all the responses—just listen and follow along. Many churches offer missalettes or guides.

• You can watch and pray silently if you’re unsure. Participation grows over time.

• Kneeling, standing, and sitting have meaning but don’t worry about doing everything perfectly at first.

• If you’re not yet receiving Communion, you’re still fully welcome. You can make a spiritual communion or ask for a blessing.

A Foretaste of Heaven

The Mass is not just a ritual. It is an encounter with the living Christ, a participation in His sacrifice, and a communion with His Body—the Church. Whether you’re returning to faith or discovering it anew, let the beauty and mystery of the Mass draw you closer to God, week by week.

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,
(bow at the next lines)

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.
