Vatican’s new document defends monogamy amid modern relationship debates
Pope Leo XIV has released a new document titled One Flesh – In Praise of Monogamy, reaffirming the Catholic Church’s stance on marriage. The text defends the principle of lifelong union between one man and one woman while addressing modern challenges like polygamy and polyamory.
Cardinal Víctor Manuel Fernández, head of the Vatican’s doctrine office, explained that the document seeks to clarify why the Church upholds exclusive, lifelong partnerships as the foundation of marriage.
The document opens by declaring that 'unity is the founding property' of marriage. It argues that the 'unitive purpose of sexuality' extends beyond procreation, marking a subtle shift in how the Church discusses intimacy within wedlock. This perspective contrasts with traditional teachings that often emphasised childbearing as the primary purpose of marital relations.
Polygamy, described as a long-standing 'pastoral challenge' in African Catholic communities, comes under direct criticism. The text also rejects polyamory and adultery, framing them as incompatible with the Church’s vision of love. Cardinal Fernández, an Argentine theologian, stated that the document aims to offer reasoned support for monogamy rather than merely condemn alternatives.
While the Church reaffirms its opposition to non-monogamous relationships, the document acknowledges their growing visibility in Western societies. This recognition reflects a broader cultural shift, even as the Vatican maintains its doctrinal position.
The release of One Flesh – In Praise of Monogamy signals a continued emphasis on traditional marriage within Catholicism. It also subtly expands the Church’s discussion of marital intimacy beyond reproduction. The text now serves as an official reference for bishops and theologians addressing questions about modern relationships.
