If the politician is automatically excommunicated, what is the punishment for a Priest or Bishop to give this person Communion, or what is the punishment for a Cardinal who performs a funeral service for a dead Senator who was automatically excommunicated.
Good question. . .I wish the leadership of the Church would make public answers to your question and mine.
The punishment is on the excommunicant. By receiving the body and blood while in a state of mortal sin, they have committed a sacrilege.
