The third reading in a Catholic wedding is always chosen from one of the four gospels. These books of the Bible were recorded during the latter half of the first century A.D. Each tells the story of Jesus through the memory of a distinct Christian community, presenting a unique picture of his early life, ministry, death, and resurrection.
Many of the gospel readings for Catholic weddings are not explicitly about marriage but about the love of Christians for one another and about the call to discipleship. The passages remind us that Christian marriage is a particular way of living out one’s discipleship in Jesus Christ.
