Bridal theology

Within the Christian tradition, bridal theology, also referred to as mystical marriage, is the New Testament portrayal of communion with Jesus as a marriage, and God's reign as a wedding banquet. This tradition in turn traces back to the Hebrew Bible, especially allegorical interpretations of the erotic Song of Songs (or Song of Solomon).

In Christianity, bridal theology plays a role in the lives of those who become Catholic, Lutheran and Anglican nuns and religious sisters; for this reason, nuns and religious sisters are often termed "brides of Christ". Additionally, those who dedicate their lives as consecrated virgins live as a "spouse of Christ", spending their lives devoted to serving in the local church and praying for all the faithful (being gifted a breviary after undergoing the rite). Expanding on this, in The Harvard Ichthus, Jane Thomas explained that in a sense, all Christian women are brides of Christ:

Just as these Sisters are the brides of Christ, so too is every married woman (whether she sees it or not), for just as Jesus dwells in school children, so too does he dwell in the husband of a married woman. In this way, she too is married to Christ. Paul's instruction, "Wives, submit to your own husbands, as to the Lord" (Ep 5:22), is more than just a metaphor meant to illustrate a degree of submission. Rather, he is describing a spiritual reality, contingent on Christ's indwelling in the husband. And who is the person to whom the wife submits? A man who loved his bride the church so much that he died for her sake. [...] If I am called to marriage, then I am called to love Jesus and minister to Jesus by pouring out my love to one man, my husband. When I make him laugh, when I bring him joy, when I love him even at his worst, I am doing these things to Jesus.

Bridal theology has influenced the works of, among others, Henry Suso, Catherine of Siena, Teresa of Ávila, Gregory the Great and Bernard of Clairvaux.
