I have now found a good translation at a Catholic site of what Pope Francis said to a Lutheran woman about taking communion at her husband's Catholic church, although it doesn’t help much. “Talk to the Lord and then go forward” is why we have 35,000 different Christian denominations many with no authority higher than the pastor who organized the church.
”I can only respond to your question with a question: what can I do with my husband that the Lord’s Supper might accompany me on my path? It’s a problem that each must answer [for themselves], but a pastor-friend once told me that “We believe that the Lord is present there, he is present” – you believe that the Lord is present. And what's the difference? There are explanations, interpretations, but life is bigger than explanations and interpretations. Always refer back to your baptism – one faith, one baptism, one Lord: this Paul tells us; and then consequences come later.
I would never dare to give permission to do this, because it’s not my own competence. One baptism, one Lord, one faith. Talk to the Lord and then go forward. [Pauses] And I wouldn't dare – I don’t dare say anything more.” http://whispersintheloggia.blogspot.com/2015/11/life-is-bigger-than-explanations-to.html
I’m still left with the puzzle that what Lutherans call “present” and what Catholics call “present” have not been the same, and for many Protestants and those who came later like non-denominational denominations of the last 50 years, there isn’t even a “present,” just a memorial.
