Another way to receive grace and be closed to God when we are unable to attend Holy Mass is through a spiritual communion. This is a prayer that expresses to God the desire to be close to him in the Eucharist.
St. Teresa of Avila wrote in The Way of Perfection: “When you do not receive communion and you do not attend Mass, you can make a spiritual communion, which is a most beneficial practice; by it the love of God will be greatly impressed on you.”
St. Jean Vianney said: ” If we are deprived of Sacramental Communion, let us replace it, as far as we can, by spiritual communion, which we can make every moment; for we ought to have always a burning desire to receive the good God. Communion is to the soul like blowing a fire that is beginning to go out, but that has still plenty of hot embers; we blow, and the fire burns again.”
St. Thomas Aquinas distinguished the physical and spiritual reception of the Eucharist, and described Spiritual Communion as, “an ardent desire to receive Jesus in the most holy sacrament and lovingly embrace him”.
St. Leonard of Port Maurice said: “If you practice the holy exercise of spiritual Communion several times each day, within a month you will see your heart completely changed.”
More recently, Pope Benedict XVI: “Even in cases where it is not possible to receive sacramental communion, participation at Mass remains necessary, important, meaningful and fruitful. In such circumstances it is beneficial to cultivate a desire for full union with Christ through the practice of spiritual communion, praised by Pope John Paul II and recommended by saints who were masters of the spiritual life”.
Fr. John Zuhlsdorf, in addition to making a great podcast on prayers during an epidemic, compiled a few famous versions spiritual communion prayers throughout history, available here. I have included them below.
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 there, and unite myself wholly to You. Never permit me to be separated from You. Amen.”
Rafael Merry del Val:
At Thy feet, O my Jesus, I prostrate myself and I offer Thee 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.
As I cannot this day enjoy the happiness of assisting at the holy Mysteries, O my God! I transport myself in spirit at the foot of Thine altar; I unite with the Church, which by the hands of the priest, offers Thee Thine adorable Son in the Holy Sacrifice; I offer myself with Him, by Him, and in His Name. I adore, I praise, and thank Thee, imploring Thy mercy, invoking Thine assistance, and presenting Thee the homage I owe Thee as my Creator, the love due to Thee as my Savior.
Apply to my soul, I beseech Thee, O merciful Jesus, Thine infinite merits; apply them also to those for whom I particularly wish to pray. I desire to communicate spiritually, that Thy Blood may purify, Thy Flesh strengthen, and Thy Spirit sanctify me. May I never forget that Thou, my divine Redeemer, hast died for me; may I die to all that is not Thee, that hereafter I may live eternally with Thee. Amen.
O Immaculate Queen of Heaven and Earth, Mother of God and Mediatrix of every grace: I believe that Thy dearly beloved Son, Our Lord Jesus Christ, is truly, really, and substantially contained in the Most Blessed Sacrament. I love Him above all things and I long to receive Him into my heart. Since I cannot now receive Him sacramentally, be so good as to place Him spiritually in my soul. O my Jesus, I embrace Thee as One who has already come, and I unite myself entirely to Thee. Never permit me to be separated from Thee. Amen.
