“The indissolubility of the marriage bond is not merely a legal or ethical rule. It is a beautiful, sacramental, and spiritual reality. In created nature, the bond expresses something of the eternal nature of God, and in the sacrament of marriage between baptized persons it is ‘integrated into God’s covenant with man,’ a ‘covenant guaranteed by God’s fidelity.’ The marriage bond is indissoluble because the Gospel covenant is indissoluble, for the sacrament signifies Christ’s permanent union with his Church.”
