DOMA and Prop 8: The reality of God's definition of marriage cannot be changed
The Supreme Court’s decision to strike down the federal Defense of Marriage Act (DOMA) and to dismiss the California Proposition 8 appeal does not change the reality of marriage, nor does it change the Archdiocese of St. Louis's responsibility to defend marriage as being between one man and one woman. It is important to note that marriage predates both the U.S. government and Western civilization.
From a Catholic perspective, it is not enough to offer the Church’s position on same-sex union without also saying how it fits into a broader understanding of the sacrament of marriage, human sexuality, and the Gospel of Life as taught by Blessed John Paul II. The vocation to serve God and society through married life is a sacred union in which man and woman become one flesh. The Catholic Church does not condemn individuals for having same-sex attraction. She teaches that all people are called to responsibility regarding sexuality. The sexual union of a man and woman, when not obstructed by contraceptives, is the kind that is open to life even if new life is not the result.
We understand that married persons imitate the way Christ offers His body completely and permanently to the Church so that we might have life, and have it abundantly. This truth is written into our bodies as well as on the pages of the Old and New Testaments. While the law can allow other things to be called marriage, it cannot make them into the kind of union that is marriage.
