Two approved Acts of Spiritual Communion.
Act of Spiritual Communion composed by the saintly Raphael Cardinal Merry del Val about a century ago:
At Thy feet, O my Jesus, I prostrate myself and I offer Thee the repentance of my contrite heart, which is humbled in its nothingness and in Thy holy presence. I adore Thee in the Sacrament of Thy love, the ineffable Eucharist. I desire to receive Thee into the poor dwelling that my heart offers Thee. While waiting for the happiness of sacramental Communion, I wish to possess Thee in spirit. Come to me, O my Jesus, since I, for my part, am coming to Thee! May Thy love embrace my whole being in life and in death. I believe in Thee, I hope in Thee, I love Thee. Amen.
Act of Spiritual Communion composed by St. Alphonsus Liguori:
My Jesus, I believe that You are present in the Most Blessed Sacrament. I love You above all things, and I desire to receive You into my soul. Since I cannot now receive You sacramentally, come at least spiritually into my heart. I embrace You as if You were already come, and I unite myself wholly to You. Never permit me to be separated from You. Amen.
