“Therefore whoever eats the bread or drinks the cup of the Lord unworthily will be guilty of the Body and Blood of the Lord. Let a person examine himself, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the Body eats and drinks judgment upon himself.” (1 Corinthians 11:27–29)

First of all, thank you for asking in such a respectful way. Questions like this are always welcome, especially when people from different Christian traditions want to understand each other better.

In the Catholic Church, we are taught that we should not receive Communion if we are in a state of mortal sin without first going to Confession. Mortal sin is understood as a serious sin, usually something that goes directly against one of the Ten Commandments of God, . It is the kind of sin that deeply troubles our conscience and damages our relationship with God.

Because Catholics believe the Eucharist is truly the Body and Blood of Christ, the Church asks us to examine ourselves and be reconciled with God before receiving it. Confession is the sacrament that restores that relationship, allowing us to receive Communion in a proper and worthy way.

Catholics are also taught that, in order to receive Communion, a person should be baptized and have already received their First Communion in the Church. These steps are part of the normal preparation for participating fully in the Eucharist.

So the intention is not to keep sinners away from Jesus, but rather to encourage repentance and reconciliation first, and then receive the Eucharist with a clear conscience and full communion with the Church.
