Abstract
This abstract aims to analyze the impact of the Reformation on marriage. The theological vision of Luther’s Reformation had a double effect on marriage: 1. Marriage was not a sacrament, so it recovered its original character of conventional agreement about the communion of life. 2. It was accepted that marriages could be dissolved through divorce. However, the combination of the customs changed because of the European wars on religion, which disseminated syphilis, and the prospective spouses could not live together before the ceremony. These attitudes were shared by Protestants and Catholics and contributed to stiffening the sexual morality of future centuries. Since then, spouses must be of different sex, bound in a monogamous relationship for life, and prenuptial sex was prohibited. How did this mindset cross time until now? Does Reformation still influence heterosexual and same-sex marriage nowadays?
