Justice & Chastity: The Marriage Debt
In our modern, independent, self-centered world, the idea of another person having rights over someone else’s body is likely to elicit ideas of enslavement and abuse. It will likely come as a shock to many married Catholics that their marriage vows formed a contract by which they gave their spouse a right to sexual intercourse with them. This right to the marital act is called the marital debt (debitum nuptiale). Now whenever we are talking about a debt we are talking about something that pertains to the virtue of justice.
