Today we often hear that a sacramental marriage is outdated. In this article, the author shows that the sacrament of marriage is still current. Today we can see that many people lives in free unions – defacto unions. However, they can choose marriage, which is a formal relationship. The sacramental marriage is modern. There is no such thing as one marriage according to life and another according to law. Pope Benedict XVI said: ,,marriage is one thing alone, it constitutes a real legal bond between the man and the woman, a bond which sustains the authentic conjugal dynamic of life and love”. Sacramental marriage does not need ads to be promoted but needs support in proclaiming the truth about him.
