Cardinal Raymond Burke weighs in. From The National Catholic Register:
The only key to the correct interpretation of Amoris Laetitia is the constant teaching of the Church and her discipline that safeguards and fosters this teaching. Pope Francis makes clear, from the beginning, that the post-synodal apostolic exhortation is not an act of the magisterium (No. 3). The very form of the document confirms the same. It is written as a reflection of the Holy Father on the work of the last two sessions of the Synod of Bishops. The Holy Father is proposing what he personally believes is the will of Christ for His Church, but he does not intend to impose his point of view, nor to condemn those who insist on what he calls “a more rigorous pastoral care.” … There is no consistent effort to relate the text, in general, or these citations to the magisterium, the Fathers of the Church and other proven authors. What is more, as noted above, a document which is the fruit of the Synod of Bishops must always be read in the light of the purpose of the Synod itself, namely, to safeguard and foster what the Church has always taught and practiced in accord with her teaching. In other words, a post-synodal apostolic exhortation, by its very nature, does not propose new doctrine and discipline but applies the perennial doctrine and discipline to the situation of the world at the time.
