Cardinal Víctor Manuel Fernández, Prefect of the Dicastery for the Doctrine of the Faith, said the new document on marriage is intended for the whole Church but can also be applied to local cultural situations. He explained that in a world shaped by rapid technological growth, people may begin to see themselves as without limits, which can blur the value of exclusive love between two people. The Note aims to offer positive reasons—drawn from Scripture, Christian tradition, philosophy, and even poetry—for choosing a unique and lifelong union. Although lengthy, the text brings together a wide range of authors to highlight themes such as reciprocity and the deep unity of marriage, forming what the Prefect describes as a “beautiful mosaic” on monogamy. For those seeking only a brief summary, he points to the final chapter and conclusion, but encourages readers to explore the entire document to appreciate the full richness of the topic.

The document highlights that true marital love is built on free consent, mutual respect, and a commitment that protects each person’s dignity. It stresses that marriage is not a form of possession or control, and that healthy relationships allow room for personal freedom, reflection, and growth. At the same time, it calls couples to remain close, practise charity, and support each other through prayer, shared responsibility, and service to others—especially the poor. The Note concludes that real unity between two spouses forms the foundation of lifelong commitment, offering a path of love that grows over time and points towards a promise “of the infinite.”
