The only possible way a person could want this is if their religion is ecumenism. Logical people on both sides understand that their is a gulf of difference between Catholic and Lutheran theology, especially on the Eucharist. Anyone willing to ignore the irreconcilable differences doesn’t care that much for the truth, but wants to put faux unity ahead of everything else.
Do I dare ask what the Lutheran theology is on the Eucharist?
This is just one more thing that is very troubling about this Pope. And he doesn’t seem to care - anyone who wants to keep the tradition is a ‘deplorable’ in his eyes.
