Your point makes no sense. Who do you take Communion from? Is he a sinner? Do you question him before you take the piece of bread?
Don’t move the goalposts.
Priests are said to be able to call Christ down and confect Him in the eucharist.
Non-Catholics do NOT make that claim of their ministers, nor do our pastors handle the elements and lay them on our tongue.
Nor did you answer the question.
Why is it OK for a priest in mortal sin to serve communion but the laity in mortal sin not be able to receive it?
