The Act of Spiritual Communion
1. Make an act of faith.
The key here is to express to the Lord: our faith in his merciful love and his real presence in the Eucharist. You can come up with your own prayer or use a more traditional version. For example (USCCB):
O my God, I firmly believe that you are one God in three divine Persons, Father, Son, and Holy Spirit. I believe that your divine Son became man and died for our sins and that he will come to judge the living and the dead. I believe these and all the truths which the Holy Catholic Church teaches because you have revealed them who are eternal truth and wisdom, who can neither deceive nor be deceived.
In this faith I intend to live and die.
2. Make an act of love
O Lord God, I love you above all things and I love my neighbor for your sake because you are the highest, infinite and perfect good, worthy of all my love.
In this love I intend to live and die.
3. Express our desire to receive him
4. Invite Jesus to come into our hearts spiritually.
With a humble and contrite heart, we ask the Lord to come to us just as He would if we were able to receive the sacrament.
“This puts us in the state of mind of being in union with Jesus,” Father White explained. “It’s very simple, it only takes a moment, and we can do it during our work, our studies or anything else we may be doing.”
We find each one of these steps summed up nicely in a beautiful act of Spiritual Communion by St. Alphonsus Maria de Liguori
“My Jesus, I believe that Thou art present in the Blessed Sacrament. I love Thee above all things and I desire Thee in my soul. Since I cannot now receive Thee sacramentally, come at least spiritually into my heart. As though thou wert already there, I embrace Thee and unite myself wholly to Thee; permit not that I should ever be separated from Thee”(St. Alphonsus Maria de’ Liguori).
