The Vatican on Tuesday released a new doctrinal note on monogamy approved by Pope Leo XIV. The Dicastery for the Doctrine of the Faith said sex strengthens the bond between couples and should not be treated as only a means to have children.
The document, titled Una Caro (one flesh) – In Praise of Monogamy, describes sexuality as a gift that guides people toward self-giving and the good of their partner. It says conjugal love can lead to children, but not every sexual act must aim at procreation. It adds that marriage keeps its essential character even when couples cannot have children.
The note restates the Church’s teaching that marriage is a union between one woman and one man. It also warns against treating marriage as possession, criticising desires that lead to violence, coercion, pressure or control.
Cardinal Prefect Víctor Manuel Fernández presented the text on the International Day for the Elimination of Violence against Women, saying the timing was “no coincidence”.
Cardinal Fernandez explained that the note responds to modern cultural pressures, including a belief that individuals have no limits. He said this idea can obscure the value of exclusive love, which requires freely renouncing other possibilities.
The document draws on Scripture, Christian tradition, philosophy and poetry. The DDF said this wide range of sources aims to support a deeper understanding of monogamy and help marriage groups reflect on the theme. Fernández said the many references create a “mosaic” that highlights unity, reciprocity and the depth of conjugal relationships.
The final chapter offers a short summary for readers seeking a brief explanation of the Church’s view. It focuses on mutual belonging and the meaning of conjugal charity. The DDF, however, encourages readers to consider the full text to understand the scope of the issues involved.
