“The sacrament of Matrimony establishes a perpetual and exclusive bond between the spouses. God himself seals the consent of the spouses. Therefore, a marriage which is ratified and consummated between baptized persons can never be dissolved. Furthermore, this sacrament bestows upon the spouses the grace necessary to attain holiness in their married life and to accept responsibly the gift of children and provide for their education.”
