God said to Adam and Eve: “Be fruitful and multiply, and fill the earth and subdue it” (Gen 1:28). He asked our first parents to form a family and to work. He asked our first parents to form two loving communions of persons—one familial communion and one worker communion—in imitation of the love in the trinitarian communion of Persons.
The invitation to form the two human communions is, in a certain sense, logically included in the creation of human persons in God’s image. Since we are like God, we should act like God—i.e., we should love. When we love, we form loving unions with other persons. When God invited us to enter these two communions, He not only confirmed His creative act, but He gave each of us an opportunity to become more and more like Him. Every act a person does is “contained” in his consciousness. Every conscious act shapes us. Consequently, through our conscious acts, we can shape ourselves into more and more perfect images of God or into more and more imperfect images of God. Since we are images of God, we should always try to become more and more like Him through repeated God-like acts. Conversely, repeated ungodly acts shape us more and more into distorted images of God. The invitation to form the two communions of love—i.e., to imitate God by loving in the family and in the workplace, is an invitation to shape ourselves more and more into images of God. In other words, by acting as God acts, we become more and more what we already are: images of God. It is this concept that allowed Pope St. John Paul II to ask families to “become what you are” (Familiaris Consortio, 17).
Of course, the familial communion is more fundamental. The familial communion mirrors the divine communion more profoundly than the communion of workers. The familial communion imitates the trinitarian communion more closely in the limitless self-gift. In the family, as in the Trinity, each member gives all that he or she is, while each person in the worker communion gives all that he or she has.
