Marriage is presented in Scripture as an image of Christ and the Church. It is also presented even earlier as an image of the Trinity. "In the image of God created He him, male and female created He them." St. Gregory the Theologian and St. John Chrysostom exposed the Trinitarian image of marriage in Scripture.
Above all, the Trinitarian image of Marriage is found in Christ, the Husband and Wife form the primary trinity of the family.
