The Prefect of the CDF says there are no circumstances whatsoever where the divorced and remarried without an annulment can receive Holy Communion with impunity. If what you say is correct then the Pope and the Head of his doctrinal dicastery are in disagreement.
Of course, it is not just Cardinal Mueller who hold this view, there are many, many more cardinals, bishops and priests throughout the Universal Church who agree with him and disagree with your interpretation of what the Pope believes.
How do you account for this discrepancy?
