I wrote a summary of this letter for Crux:
As the Year of Mercy ended, Pope Francis signed an apostolic letter imploring us to continue being merciful called Misericordia et Misera. This letter continues key themes of Francis. The title refers to the mercy with misery Jesus grants the woman caught in adultery. I intend to provide the key lines here with minimal commentary where needed.
He gets to his thesis fast: “Mercy cannot become a mere parenthesis in the life of the Church; it constitutes her very existence, through which the profound truths of the Gospel are made manifest and tangible. Everything is revealed in mercy; everything is resolved in the merciful love of the Father.” (1 – numbers in brackets refer to paragraphs in the document).
“Forgiveness is the most visible sign of the Father’s love, which Jesus sought to reveal by his entire life. Every page of the Gospel is marked by this imperative of a love that loves to the point of forgiveness.” (2)
