Focusing on the pain and alienation people feel is no excuse to change the nature of a Sacrament with respect to the reception of Holy Communion, but it can become a means through which to legitimate divorce.
Such rationales often form attacks on Catholic Sacraments. These are things such as the personal shame involved, how difficult it is and that it constitutes a "pastoral" problem.
It is in fact the "pastoral" problem which has involved attacks on other Catholic doctrines, like sexual affairs, homosexuality and women priests.
Anything, including the murder of unborn babies, can be justified by such approaches, but Tornielli is more interested in pointing out that this dissident priest has written a book on the subject and he claims that Pope Benedict has even considered this to be an open question. The question is also handled by another fallacious course of reasoning, by an appeal to archaism/ Tornielli continues:
This "flexibility in rigor" [Tornielli is concerned with rigour, is he?] also characterized the practice of the early centuries of the Church. Similar positions were expressed, the German theologian points out, by Joseph Ratzinger who, in a 1972 essay, wrote that underneath or within the classical magisterium "there has always been, in practical ministry, a more elastic practice that has never been regarded as entirely consistent with the true faith of the Church, but that has never been totally ruled out"; regulated admission to the sacraments of the persons concerned, Ratzinger said, "is fully in line with the tradition of the Church."
The Holy Father may have written that questionable statement before he was Pope, but that doesn't mean he still subscribes to those opinions, nor does it mean that he's going to bulldoze over two thousand years of consistent tradition with regard to the Sacrament of Marriage in order to satisfy a small group of elderly dissidents in Austria and their disobedient leaders.
