Marriage has a unique place because it speaks of an absolute faithfulness, a covenant between radically different persons, male and female; and so it echoes the absolute covenant of God with his chosen, a covenant between radically different partners.

In this quote, Rowan Williams reflects on the profound and sacred nature of marriage, comparing it to the covenant between God and humanity. He emphasizes that marriage represents a unique and deep commitment between two radically different persons, namely a man and a woman. Williams sees this difference as fundamental to the relationship, suggesting that the union of male and female reflects a kind of absolute faithfulness that mirrors the covenant between God and his people.

Williams connects the idea of marriage to a covenant, a term often used in religious contexts to describe a sacred agreement. He argues that, just as the covenant between God and his chosen people is a bond of deep commitment and faithfulness, so too is marriage. This parallel implies that marriage is not merely a social contract or legal arrangement, but a sacred and spiritual bond that mirrors the profound connection that exists in religious covenants. The reference to God’s covenant suggests that the relationship in marriage is not just between the individuals but also involves a higher, divine connection.

The mention of the radical differences between the partners in marriage—man and woman—emphasizes that marriage is not about two identical beings but about two distinct individuals coming together in a profound, complementary union. This idea aligns with Williams’s view that the diversity between the partners in marriage mirrors the diverse nature of the covenant between God and humanity, highlighting the uniqueness and complementarity of the relationship.

Ultimately, Williams’s quote underscores that marriage, in its ideal form, is a deeply spiritual and sacred relationship, defined by a commitment that echoes the divine covenant. He suggests that the faithfulness in marriage is not just an earthly promise, but a reflection of the absolute and sacred faithfulness of God's covenant with his people, reinforcing the spiritual and sacred dimensions of the marital bond.
