Criticism by Ray Burke is grounds for canonization. As for future Popes, according to St. Malachy, they won't be in Rome, if there are any. If we merge with Orthodoxy, you will find that their approach to remarriage is even more lenient than Francis. The reality is that the Synods and A.L. codified what happens in most parishes already all over the world. This was the approach a priest took with my mother-in-law, whose first husband was dead but her husband's ex was alive and she was discomforted by trad tongue wagging on this issue. Had it not been for that, she would have happily kept going to Communion and felt the pressence of Christ. The Burke line on this issue has always been based on misreading of Mark's Gospel and Paul's letter to Corinthians.
