During the suspension of Masses and when it is not feasible to receive the Eucharist, Catholics may pray the following:
An Act of Spiritual Communion (Modern Translation)
O 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 into 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 myself wholly to You. Never permit me to be separated from You.
