And God created the human in his image; in God’s image he created them.
Image comes up twice in this verse because faith, which belongs to the understanding, is called his image, but love, which belongs to the will, is called God’s image. Love comes second in the spiritual person but first in the heavenly person.
Male and female he created them.
The inner meaning of male and female was very familiar to the earliest church, although their successors lost touch with this secret when they lost sight of any deeper import to the Word.
These earliest people found their greatest happiness and pleasure in marriage. Whenever they could possibly draw a comparison between something else and marriage, they did so, in order to perceive the happiness of marriage in that other entity. Being people of depth, they enjoyed only the deeper aspects of things. External objects were just for looking at; their thoughts were occupied instead with the things those objects represented. External objects, then, were nothing to them, serving only as a springboard for reflection on inner realities, and these for contemplation of heavenly realities and so of the Lord, who was everything to them. The same process caused them to reflect on the heavenly marriage, which they could tell was the source of the happiness in their own marriages.
As a result, they called the understanding in the spiritual being male and the will there female; and when the two worked together, they called it a marriage.
That religion initiated the practice, which became quite common, of calling the church Daughter or Virgin (as in “the Virgin Zion,” “the Virgin Jerusalem”) and also Wife, on account of its desire for good.
