when are you not allowed to receive communion

For Catholics, you generally should not receive Communion if you are conscious of grave sin and have not yet gone to sacramental confession, if you are excommunicated or under an interdict, if you are not Catholic, or if you have not kept the one-hour fast beforehand. Catholic guidance also says those who are not in full communion with the Church are ordinarily not admitted, with limited exceptions for certain Christian groups under canon law.

Common situations

• You are aware of serious sin and have not been absolved in confession.

• You are not baptized or are not Catholic.

• You have been excommunicated or interdicted.

• You have not fasted for at least one hour before Communion.

• You are not properly disposed to receive, such as being in an objectively irregular situation the Church considers incompatible with receiving.

Practical note

Catholic teaching distinguishes between being “allowed” in a legal sense and being spiritually ready. The usual advice is to examine your conscience, speak with a priest if you are unsure, and avoid receiving until the situation is resolved.

Other Christian traditions

Rules are different in other churches. Some Protestant communities invite all baptized believers, while others have their own restrictions, so the answer depends on the denomination and local practice.
