No, because Tonsignor Pope's interpretation imports external ideas into the text as key to its interpretation. One would not find all that drivel in John 2 about Mary arranging a "mystical marriage" or "they have no wine" being an intercessory prayer, unless those things were already assumed to be true of Mary.
That's the problem with much allegory. The key to interpreting the allegory is external to it. Tonsignor Pope is begging the question in a big way.
Well said, in other words, he is reading into Scripture what he wants it to say, as Scripture can be an abused servant for Rome that is compelled to support her traditions.
