Prayers in place of Eucharist
Act of Spiritual Communion (from Project Canterbury)
Now make a special effort to realize the presence of Jesus in your soul, and make your act of Spiritual Communion, remembering how at countless altars of the Church the Holy Sacrifice is being pleaded and souls fed sacramentally by the Body and Blood of Christ.
In union, O Dear Lord, with the faithful at every Altar of Thy Church, where Thy blessed Body and Blood are being offered to the Father, I desire to offer Thee praise and thanksgiving. I present to Thee my soul and body, with the earnest wish that I may ever be united to Thee. And since I cannot now receive Thee sacramentally, I beseech Thee to come spiritually into my heart. I unite myself to Thee and embrace Thee with all the affections of my soul. O let nothing ever separate me from Thee. Let me live and die in Thy love.–Amen.
Grant, O Lord Jesus Christ, that as the hem of Thy garment, touched in faith, healed the woman who could not touch Thy Body, so the soul of Thy servant may be healed by like faith in Thee, Whom I cannot now sacramentally receive; through Thy tender mercy, Who livest and reignest with the Father in the unity of the Holy Ghost ever one God.–Amen.

Spiritual Communion Prayer
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 in my soul.
Since I cannot at this moment receive you sacramentally,
Come at least spiritually into my heart.
I embrace you as if you were already there
And unite me wholly to you.
Never permit me to be separated from you.
St. Augustine’s Prayer Book (published by Forward Movement) has a good section on spiritual communion, beginning on p. 290
