Who Can Receive Communion at a Catholic Mass?

Catholic Faith and Sacraments

Catholics ordinarily receive Communion when properly prepared and not conscious of unconfessed mortal sin. Attendance at Mass is open to visitors, but receiving the Eucharist also expresses communion in Catholic faith and sacramental life.

For Catholics

  • Have received the necessary sacramental preparation, including First Communion.
  • If conscious of grave sin, ordinarily receive sacramental absolution before Communion.
  • Observe the Eucharistic fast: ordinarily one hour before Communion, except water and medicine. Different provisions apply to the elderly, the sick and those who care for them.

The Church provides a narrow exception when there is a grave reason to receive and no opportunity for confession: perfect contrition and the intention to confess as soon as possible are required. Ask a priest about an actual situation rather than assuming embarrassment or convenience establishes the exception.

For other Christians

Most Christians who are not in full communion with the Catholic Church do not ordinarily receive at a Catholic Mass. There are specific provisions for members of Eastern Churches and limited exceptional circumstances for other baptized Christians. These are governed by Church law and pastoral judgment; ask the priest in advance.

For someone who is not baptized

Do not receive Communion yet. You can attend Mass, pray, ask questions and explore Christian initiation. There is no need to leave during Communion.

If you are not receiving today

Remain in your place and pray quietly. You might ask Christ to draw you closer and guide your next step. Receiving a blessing in the procession is a local practice, not something to assume everywhere.

Questions about your own circumstances

Marriage circumstances, reception into the Church, a previous confession or an uncertain baptism may need a private conversation. A webpage cannot determine your personal sacramental situation. Our confession guide can help you prepare for one common next step.
