The goal of the path or food for the journey?

So the Pope speaks about a situation with a Lutheran and Roman Catholic husband and wife and their complaint about not being able for both to commune together:

I think of how the Lord told us when he gave us this mandatum to “do this in memory of me,” and when we share the Lord’s Supper, we recall and we imitate the same as the Lord. And there will be the Lord’s Supper in the final banquet in the new Jerusalem – it’ll be there! But that will be the last one… in the meantime, I ask myself and don’t know how to respond – what you’re asking me, I ask myself the question. To share the Lord’s banquet: is it the goal of the path or is it the viaticum [etym. “to accompany you on the journey”] for walking together? I leave that question to the theologians and those who understand.
It’s true that in a certain sense, to share means that there aren’t differences between us, that we have the same doctrine – underscoring that word, a difficult word to understand. But I ask myself: but don’t we have the same Baptism? If we have the same Baptism, shouldn’t we be walking together? And you’re a witness of a likewise profound journey, a journey of marriage: itself a journey of family and human love and of a shared faith, no? We have the same Baptism.
When you feel yourself a sinner – and I’m much more of a sinner – when your husband feels he’s sinned, you go forward to the Lord and ask forgiveness; your husband does the same and also goes to the priest and asks absolution, [thus] I’m healed and kept alive in my Baptism. When you pray together, that Baptism grows, becomes stronger. When you teach your kids who is Jesus? Why did Jesus come? What did Jesus do for us?, you’re doing the same thing, whether in the Lutheran language or the Catholic one, but it’s the same.
The question [Pope draws question mark with his finger]…. The supper? There are questions that only if one is sincere with oneself and the little theological light one has, must be responded to on one’s own. See for yourself. This is my body. This is my blood. Do it in remembrance of me – this is a viaticum that helps us to journey on.
I once had a great friendship with a bishop who went a little wrong – 48 years old, he married [then had] two children. This made for great discomfort in him – a Catholic wife, Catholic children, him a bishop. He accompanied them on Sunday, his wife and children, to Mass, and then went to worship with his community…. It was a step toward his participation in the Lord’s Supper. Then he went forward, then the Lord called him [to realize] “I’m not right.”
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.

The ELCA has already spoken and declared that whatever differences, they are not church dividing.  This, of course, in view of the coming 500th anniversary of the Reformation in 2017, and follow up to the Declaration on the Way, a major joint statement from the USCCB and Evangelical Lutheran Church of America already made public in November.
