The Archbishop there, Michael Sheehan, has issued a pastoral letter that was read at all masses this past weekend.
We have three groups of people who are living contrary to the Gospel teaching on marriage: those who cohabit; those who have a merely civil union with no previous marriage; and those who have a civil union who were married before. These people are objectively living in a state of mortal sin and may not receive Holy Communion. They are in great spiritual danger. At the best – and this is, sadly, often the case – they are ignorant of God’s plan for man and woman. At the worst, they are contemptuous of God’s commandments and His sacraments.
He goes on to explain:
These people may not be commissioned as Extraordinary Ministers of Holy Communion, not only because of scandal, but even more because one commits the sin of sacrilege by administering a Sacrament in the state of mortal sin.
Nor are such people to be admitted to the role of sponsor for Baptism or Confirmation, as is clearly stated on the Archdiocesan Affidavit for a Sponsor. It is critical for the sponsor to be a practicing Catholic – and can anyone be seriously called a practicing Catholic who is not able to receive the sacraments because they are living in sin?
