|Catechism of the Catholic Church on Matrimony|
Sacred Scripture begins with the creation and union of man and woman and ends with "the wedding feast of the Lamb" (Rev 19:7, 9). Scripture often refers to marriage, its origin and purpose, the meaning God gave to it, and its renewal in the covenant made by Jesus with his Church. Man and woman were created for each other.
By their marriage, the couple witnesses Christ's spousal love for the Church. One of the Nuptial Blessings in the liturgical celebration of marriage refers to this in saying, "Father, you have made the union of man and wife so holy a mystery that it symbolizes the marriage of Christ and his Church."
The Sacrament of Marriage is a covenant, which is more than a contract. Covenant always expresses a relationship between persons. The marriage covenant refers to the relationship between the husband and wife, a permanent union of persons capable of knowing and loving each other and God. The celebration of marriage is also a liturgical act, appropriately held in a public liturgy at church. Catholics are urged to celebrate their marriage within the Eucharistic Liturgy.
The Catholic Church on Same-Sex Marriage
Marriage: Unique for a Reason offers resources to assist with the education and catechesis of Catholics on why marriage is unique and why it should be promoted and protected as the union of one man and one woman. Each of the videos in this initiative, with its companion written material, is intended to be used by a priest, deacon, catechist, or teacher.
While the materials are primarily intended for a Catholic audience, it is hoped that Marriage: Unique for a Reason can be of assistance to all people of good will who seek to understand the truth and beauty of marriage. The truth about marriage is accessible to everyone because it is grounded in the nature of the human person. Promoting and protecting marriage witnesses to the dignity of every person and serves the common good.
