II. The Celebration of Marriage

From The Catechism of the Catholic Church

1623
In the Latin Church, it is ordinarily understood that the spouses, as ministers
of Christ’s grace, mutually confer upon each other the sacrament of Matrimony
by expressing their consent before the Church. In the Eastern liturgies the
minister of this sacrament (which is called “Crowning”) is the priest
or bishop who, after receiving the mutual consent of the spouses, successively
crowns the bridegroom and the bride as a sign of the marriage covenant.
