#1. Pray individually or pray with a small group (less than 10)
Begin with the Sign of the Cross
Pray the Act of Contrition

Spend a few minutes reflecting on the Word of God
Share some prayer intentions
Pray the Lord’s Prayer, a Hail Mary and a Glory Be
Pray a spiritual communion prayers. For example:
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 in the Holy Eucharist,
come at least spiritually into my soul.
I embrace You as if You were already there and I unite myself completely to You.
Lord Jesus, I ask you to never permit me to be separated from You.
Thank Jesus for this time of prayer.
Close with the Sign of the Cross.
