You were not talking about Biden or Pelosi in your post when you said.... “It is not his role to turn anyone away from the communion table.”
Clearly Canon 915 gives the priest the duty to turn SOME away from the communion table. Maybe not Biden or Pelosi. But again - to say what you said in post 60 - is not true.
You are correct. I was making a blanket statement which remains true in spite of your protestations. The priest cannot know every participant in the mass who comes forward for the elements. Canon Law relies on the individual’s fealty to its authority. This is precisely why Pelosi, Biden and others are able to flaunt Canon Law with impunity. They do not respect its authority over their worldly lives.
