“Others are said to receive the Holy Eucharist in spirit only: they are those who, inflamed with a lively faith that worketh by charity, participate in desire of this celestial food, from which they receive, if not the entire, at least very considerable fruit.” (Catechism of the Council of Trent)
ACTS OF SPIRITUAL COMMUNION
My Jesus, I believe that Thou art truly present in the Most Blessed Sacrament. I love Thee above all things, and I desire to possess Thee within my soul. Since I am unable now to receive Thee sacramentally, come at least spiritually into my heart. I embrace Thee as being already there, and unite myself wholly to Thee; never permit me to be separated from Thee. (St. Alphonsus Liguori)
Jesus, I believe in Thee, because Thou art truth itself.
Jesus, I hope in Thee, because Thou art almighty, merciful, and faithful to Thy promises.
Jesus, I love Thee, because Thou art infinitely good, and worthy of all my love.
Jesus, I desire to receive Thee. I am sorry for having offended Thee. Come to me, and never again let me be separated from Thee by sin.
Jesus, my Lord, my God, and my all!
O Jesus, my divine Saviour, like a meek and gentle lamb Thou didst offer Thyself upon the cross as a sacrifice for the whole world, and in Thine own most precious blood didst wash away our sins. On our altars Thou dost renew the sacrifice of the cross, and givest Thyself, moreover, to us as the food of our souls. I may not now receive Thee really in the Blessed Sacrament, but my soul sighs and longs for Thee, and therefore I beseech Thee in Thy love and mercy to unite Thyself to me, at least in a spiritual manner. Thou didst condescend to heal so many, when they but touched the hem of Thy garment. Permit me now, good Master, gentle Saviour, to touch Thee in spirit and with confidence that my poor soul may be freed from all its ills. Come to me, Jesus, come, and remain with me always; let me nevermore be separated from Thee by sin! I thank Thee for all Thy graces and blessings. I love Thee above all things and with my whole heart. Bless me, that I may persevere in Thy service to the end of my life.
Dear St. Joseph! how great, how innumerable were the graces which thou didst receive, when the divine Child dwelt under thy roof! How inexpressible was the happiness of thy heart, when thou didst carry Him in thy arms! Pray for me, holy foster-father of Jesus, my Saviour, that this spiritual communion may be most salutary to me, that the strength of the Most Holy Sacrament may be my support in all the trials and temptations of life, that it may strengthen me in all good, and help me to win the crown of eternal glory.
My good Lord, my dear Jesus! I am sorry for having wounded Thy loving Heart by my sins, because Thou art infinitely good, and sin displeases Thee. Like the beloved disciple, let me rest upon Thy Heart, and let me grieve, together with Thee, for the outrages that are committed against Thee in the Sacrament of Thy love. I give Thee my heart and my love, if my poor love can comfort Thee. I love Thee above all things, and I desire to possess Thee within my soul. Since I am unable now to receive Thee sacramentally, come at least spiritually into my heart, and nourish my soul unto life everlasting. Let my soul, O Lord, feel Thy sweetness. Let me taste how sweet Thou art, O Lord, that, being allured by Thy love, I may never sin by running passionately after worldly pleasures. “Thou art the God of my heart, and the God that is my portion for ever.” Oh, Thou Lamb of God, Who takest away the sins of the world, take away from me whatever may hurt me and displease Thee. Give me but Thy love and Thy grace! May the sweet flame of Thy love consume my soul, that so I may die to the world for the love of Thee, as Thou hast vouchsafed to die upon the cross for the love of me.
O Jesus! Thou hast given us in the Holy Eucharist Thy body and blood to be our spiritual nourishment, through which we may have life everlasting. Would that I were worthy to receive Thee this day in the holy communion! I desire, with all my heart, to receive the living Bread which came down from heaven.
O Lord, I am not worthy that Thou shouldst enter under my roof; say but the word, and my soul shall be healed. (Three times.) Let me taste, at least, the sweetness of a spiritual communion. Come to me, Jesus, my Lord, my Master. Come and refresh my soul. Strengthen me, that in union with Thee I may do perfectly the heavenly Father's will. Let me never be separated from Thee by sin.
Soul of Jesus, sanctify me. Body of Jesus, save me. Blood of Jesus, wash me. Water out of the side of Jesus, purify me. Passion of Jesus, comfort me. O good Jesus, hear me. Hide me within Thy sacred wounds. O Sacred Heart of Jesus, receive me. O Immaculate Heart of Mary, plead for me, and love me.
O sweet Mother, obtain for me the grace of receiving the holy communion with worthy dispositions, especially in my last sickness, when I shall be called to appear before the tribunal of God, that, through the merits of my Saviour's death and Passion, and thy intercession, I may have life everlasting. Amen.
My Saviour and my God! I am not worthy to appear before Thee, for I am a poor sinner; yet I approach Thee with confidence in Thy goodness and mercy, for Thou hast said: “Come to Me, all you that labor and are heavy-laden, and I will refresh you.” Thou wilt not despise a contrite and humble heart. I am truly sorry for my sins, because by them I have offended Thee, Who art infinitely good. Whatever may have been my foolish transgressions in the past, I love Thee now above all things, and with all my heart. I have a great desire, a vehement longing, O divine Spouse of my soul, to receive Thee in holy communion, and since I can not now receive Thee in the Blessed Sacrament, I beseech Thee to come to me spiritually and to refresh my soul with Thy sweetness.
Come, my Lord, my God, and my all! Come to me, and let me never again be separated from Thee by sin. Teach me Thy blessed ways; help me with Thy grace to practice meekness, humility, charity, and all the virtues of Thy Sacred Heart. Receive me, as one who wishes to follow Thee, and let me live and labor and suffer and pray in union with Thee, for the glory of God, for the accomplishment of the heavenly Father's will, and for the salvation of souls. Jesus! I give Thee my heart with all its affections, my soul with all its powers, and my body with all its senses. My divine Master, help me with Thy grace, that I may be ever mindful of Thy presence, and that I may be faithful to the end in Thy services. Bless me in life and in death, that I may praise Thee for ever in heaven. Amen.
