CCC 1613
Christian Mystery›SECTION TWO THE SEVEN SACRAMENTS OF THE CHURCH›CHAPTER THREE THE SACRAMENTS AT THE SERVICE OF COMMUNION›I. Marriage in God's Plan
On the threshold of his public life Jesus performs his first sign - at his mother's request - during a wedding feast. The Church attaches great importance to Jesus' presence at the wedding at Cana. She sees in it the confirmation of the goodness of marriage and the proclamation that thenceforth marriage will be an efficacious sign of Christ's presence.
