I don’t know if you have encountered this, but in the Catholic Faith, there are three criteria for grave (mortal) sins.
- full consent to the action without being coerced or under the influence of an outside influence
- full knowledge that what you were doing (at the time of the sin) was wrong
- the sin be of a grave matter
In your case, while receiving the Eucharist unworthily is a grave sin for an informed Catholic, you did not know at the time that what you were doing was wrong. It is a minor (venial) sin. Ironically, for Catholics, these sins are actually washed away and forgiven when we receive the Eucharist. Next time, while you physically cannot receive the Eucharist, I would suggest praying an Act of Spiritual Communion to seek the graces of God which can wipe away this minor sin.
Act of Spiritual Communion
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 momentreceive 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.
In the meantime, I would suggest to pray an Act of Contrition, which is said during Confession so that we recognize what we have done is wrong, seek forgiveness of God, resolve to change our ways of sin, and to make a spiritual act as an oblation of love to God in reparation for our sins.
Act of Contrition
O God, I am sorry for my sins with all my heart. In choosing to do wrong and failing to do good, I have sinned against You, whom I should love with all my heart. I firmly intend to do penance, sin no more, and to avoid whatever leads me to sin. Our Savior, Jesus Christ, suffered and died for us. In His name, my God, have mercy! Amen.
It is truly wonderful that you have the desire to become Catholic. I admire that you already seem to be developing a respect for the Holy Eucharist. My advice would be to delve into the Eucharist in your quest to become Catholic. The vastness of Christ’s love for mankind lies within that small morsel of bread and wine, waiting to be poured out upon this earth.
I will be praying for you.
God Bless,
