If there is no marriage in Heaven, what is its earthly significance? Marriage represents the image of God, and is a sign of Christ's relationship with his church, and it reaches its fulfillment in the marriage supper of the Lamb.
The Family and the Kingdom - Marriage
Marriage is used throughout Scripture as a picture of the relationship between God and His people, Christ and the Church, and even a picture of the relationships within the Trinity. In marriage, there is a deep unity possible between a man and a woman which is so radical and profound that what results is described as a new creation. This deep unity requires self-abandonment and submission.
Marriage and Divorce
God's purpose for human relationships is for sexual purity before marriage and fidelity within marriage.
Sex and the History of Christianity
The church's historical attitudes toward sex, sexuality and marriage from the first century through to the present day have often been in error. Rather than something to be repressed or brazenly flaunted, sex is a gift of God to mankind, to be enjoyed and celebrated within the God-ordained context of marriage between one man and one woman.
Augustine on the Good of Marriage (Part 1)
Augustine's theology of marriage hinges on the three goods of marriage: children, fidelity, and sacrament. The denial of these goods is a critical point in contemporary efforts to redefine marriage.
