"The church teaches that marriage is a sacrament, like the taking of communion. It is a rite that brings us closer to God. The matrimonial covenant has been raised by Christ the Lord to the dignity of a sacrament between the baptized. The law of the church is clear: it is a sacrament for a man and a woman, and its purpose is the bearing of children. A marriage that cannot be consummated is not a marriage. Antecedent and perpetual impotence to have intercourse nullifies marriage by its very nature." It's possible he's been reading over this doctrine recently. "When we marry, it will not be with God's blessing."
