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. For instance, in Chapter Eight, which some wish to interpret as the proposal of a new discipline with obvious implications for the Church’s doctrine, Pope Francis, citing his post-synodal apostolic exhortation Evangelii Gaudium, declares:
I understand those who prefer a more rigorous pastoral care which leaves no room for confusion. But I sincerely believe that Jesus wants a Church attentive to the goodness which the Holy Spirit sows in the midst of human weakness, a Mother who, while clearly expressing her objective teaching, “always does what good she can, even if in the process, her shoes get soiled by the mud of the street” (No. 308).
In other words, 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.” The personal, that is, non-magisterial, nature of the document is also evident in the fact that the references cited are principally the final report of the 2015 session of the Synod of Bishops, and the addresses and homilies of Pope Francis himself. 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.
