The Vatican published a 40-page doctrinal note that defends monogamous marriage as exclusive and lifelong. The text singles out polygamy and Western polyamory as cultural challenges to marital unity.
Cardinal Víctor Manuel Fernández presented the document at a Vatican press conference and outlined its aims. Pope Leo XIV approved the text on November 21 and authorised its publication; see Pope Leo XIV names Nigeria for background on the pope’s wider stance.
The note traces marriage in scripture, poetry and church teaching to show why unity matters. It argues that true conjugal love needs a unique and exclusive bond between two people.
What the document emphasises
The note says unity is the founding property of marriage and must be preserved. It adds that the unitive aspect of sex brings spouses closer and goes beyond just having children.
Authors argue that calling sex merely procreative misses a vital truth about marriage. They say the unitive purpose helps form the deep emotional bond between spouses.
The Vatican text criticises non-exclusive relationships as an illusion that intensity moves from person to person. It places polyamory alongside adultery and polygamy as practices that weaken the intimate gift spouses owe one another.
The authors also address polygamy as a pastoral challenge in some African contexts and ask bishops to respond pastorally. The note stresses respect for persons and warns against forms of control that harm spouses and families.
Reaction and context
The doctrinal note comes amid wider Vatican discussions about marriage and social change. Local bishops and lay groups had raised the issue in recent synodal meetings and consultations.

The text is written in Italian and aims mainly at bishops and pastoral ministers, though it addresses young people and married couples too. It offers theological, historical and pastoral reasons for choosing monogamy as the model the church upholds.
What it means for pastoral work
Bishops are urged to teach about the unitive and procreative goods of marriage in accessible ways. The note asks pastors to support couples and to defend the dignity of each spouse.
It also asks church leaders to challenge cultural trends that trivialise adultery or normalise serial or multiple partnerships. The document calls for clear catechesis that links marital fidelity to the common good and family stability.
The Vatican frames monogamy not as a limit but as a promise to grow together across a lifetime. Its publication is likely to shape parish teaching and public debate in the weeks ahead
