How often may a person receive Communion at the weekend Masses (Vigil and Sunday)?
According to the Code of Cannon Law you are allowed to receive Communion (Eucharist) once a day. An exception would be that if you are going to mass in order to participate in the Liturgy, such as having to speak at all the Masses on stewardship, etc., you could receive the Eucharist at two of the masses in which you are fully participating. So when it comes to the Eucharist once a day is enough. You may also receive the Eucharist more than once a day if you are attending different liturgies such as weddings, funerals or baptisms.
