Man's Call To Salvation

Marriage- a sacrament in which the love relationship of baptized man and woman is made a part of the new covenant and is directed toward the fulfillment of Jesus' mission; a public statement of a man and woman that they have entered a relationship of deep and lasting love in which they hope to foster their own personal fulfillment and bring up new life to responsible adulthood.
Matrimony- another word for marriage.
Divorce- the dissolution of a marriage. In the New Testament, Christ condemned divorce most decisively (Mk. 10:2-12).
Dispensation- the relaxation of the obligation of a law because of special circumstances of a case. This can be granted by proper and competent authority.
Impediment of marriage- an external fact or circumstances that forbids marriage, sacramental or legal, and makes it invalid or unlawful.
