There are so many beautiful prayers in the Catholic church! Here is a basic list that we recommend memorizing, to include the two creeds.
My Jesus, I believe that You are present in the Most Holy Sacrament.
I love You above all things,and I desire to receive You into my soul.
Since I cannot at this moment receive You sacramentally,
come at least spiritually into my heart.
I embrace You as if You were already there and unite myself wholly to You.
Never permit me to be separated from You.
Amen.
Our Father, Who art in heaven,
Hallowed be Thy name.
Thy kingdom come; Thy will be done
On earth as it is in heaven.
Give us this day our daily bread;
And forgive us our trespasses
As we forgive those who trespass against us;
And lead us not into temptation,
But deliver us from evil.
Amen.
