Again, have you read Cardinal Wuerl’s document yourself? The Catholic Herald article did nothing but basically repeat Dr. Peter Edwards’ comments, which themselves were problematic because Dr. Edwards took one line out of a 58 page document and then picked that one line apart without examining its context within the document, in relation to AL and the relatio from the two Synods on the Family, and then within the context of the Church’s broader teaching on marriage. At the very beginning of the document Wuerl himself said that that is the only proper way to understand it.
I’ve personally not made it through the whole document yet, but have now got a good start on it. I look forward to reading it more closely throughout the coming days and, God willing, offering a few reflections on it.
