If you are not yet weary of Chapter 8 of Amoris laetitia – or indeed the mere mention of the Post-Synodal Apostolic Exhortation by incipit or innuendo, my friend Fr. Gerald Murray has some observations at The Catholic Thing.
Fr. Murray begins by quoting the pivotal Familiaris consortio 84:
“[T]he Church reaffirms her practice, which is based upon Sacred Scripture, of not admitting to Eucharistic Communion divorced persons who have remarried. They are unable to be admitted thereto from the fact that their state and condition of life objectively contradict that union of love between Christ and the Church which is signified and effected by the Eucharist. Besides this, there is another special pastoral reason: if these people were admitted to the Eucharist, the faithful would be led into error and confusion regarding the Church’s teaching about the indissolubility of marriage.”
He goes on to look at how Amoris laetitia concerns itself with “scare quote” couples, that is, “irregular” couples.
The publication of Amoris Laetitia brought an end to this discipline. Now, the Church’s help and accompaniment of people publicly known to be living in “an objective state of sin”  has changed, as set forth in footnote 351 (and somewhat obscurely in footnote 336): “In certain cases, this can include the help of the sacraments.” The footnote refers to two statements Pope Francis made previously encouraging pastors to act with mildness and wide latitude when administering the sacraments of penance and the Holy Eucharist.
It’s strange that such a momentous change is effected in two footnotes, but much stranger is the change itself, which is manifestly a contradiction of the previous discipline. It makes no real difference that Holy Communion will now be given in “only certain cases” of adulterous second unions. Once some people living in adultery are allowed to receive the Holy Eucharist, while continuing to commit acts of adultery, the principles that upheld the previous discipline have been undermined. We are about to see creative ways in which the gravity of adultery and the obligation of Christians to conform their lives to the demands of the Gospel  will be minimized, if not largely denied, in matters related to the 6th Commandment.
Here we arrive at a signal difficulty in AL Chapter 8: “Naturally, every effort should be made to encourage the development of an enlightened conscience, formed and guided by the responsible and serious discernment of one’s pastor, and to encourage an ever greater trust in God’s grace. Yet conscience can do more than recognize that a given situation does not correspond objectively to the overall demands of the Gospel. It can also recognize with sincerity and honesty what for now is the most generous response which can be given to God, and come to see with a certain moral security that it is what God himself is asking amid the concrete complexity of one’s limits, while yet not fully the objective ideal.”[308 emphasis added]
The primary duty of Christian conscience is to come to know what God asks of us, and then conform our thoughts and behavior to that. A “given situation” is not in question when analyzing one’s moral responsibility, but one’s freely chosen acts in that given situation.
It’s impossible that someone even minimally instructed in the “overall demands of the Gospel” by his pastor – and thus understands that the commandment “Thou shalt not commit adultery” applies to everyone without exception – could then decide that to continue committing acts of adultery “is the most generous response” to God that he can make “for now” as a Christian.
Some have suggested that it is a mistake to say that Pope Francis has changed the discipline of the Church, and that the discipline in effect on April 7th was still in force on April 8th. But the Synod Father invited by the Holy See to officially present the document, Cardinal Christoph Schönborn, said on that occasion: “the pope affirms in a note  that the help of the sacraments may also be given ‘in certain cases.’” Did he misunderstand the pope? Did the Synod office fail to vet his remarks? Hardly. It published the remarks in written form. The media essentially reported this story in the exact same sense.
These mere snips should send you over there to read the whole thing.
