I read the document and I understand that Ratzinger said it, not you, Vico.

I did miss that it was in regards to the Orthodox, not Eastern Cath church.
The East still believes in the indissoluability of marriage.What’s “tolerated” is that they do recognize some remarriages but it is not a sacrament. At least that’s how the priest explained it and I think the document shows that too. And as ByzCan says, it is the application in practice that is different.
I think Lucky is interpreting it as the East tolerating (i.e., allowing) a second sacramental marriage and it does not. It does help to hear the difference in how the East/West church confers the sacrament, as explained by Constantine.
Unless I’m misunderstanding the document, it says that there can be an exception to the “no communion” and recognition of some second marriages, where he says…
"emergency situation in the present-day church and describe an exception that satisfies these criteria. I would like to try, with all necessary caution, to formulate a concrete proposal that seems to me to lie within this scope. Where a first marriage broke up a long time ago and in a mutually irreparable way, and where, conversely, a marriage consequently entered into has proven itself over a longer period as a moral reality and has been filled with the spirit of the faith, especially in the education of the children (so that the destruction of this second marriage would destroy a moral greatness and cause moral harm), the possibility should be granted, in a non-judicial way, based on the testimony of the pastor and church members, for the admission to Communion of those in live in such a second marriage. ".
I think this is what he means by some “toleration.” Do you interpret that differently?
