What is the basis for human society? How can we justify a society where individual initiative and freedom is upheld, while also maintaining the cohesion and order that every society needs? The answer lies in the Christian doctrine of the Trinity.
The Christian worldview understands human society as being not a product of an individual’s will, nor the outcome of a prehistoric decision by a number of persons, but a creation of God which is truly a reflection of his own triune nature.
Ultimate reality is triune – a trinity in unity. This view has always distinguished the Christian outlook from other faiths which also believe in a personal God, such as Islam and Judaism. The great God of the universe, who formed all things by His sovereign power, has revealed Himself to be a single being with a distinction of persons – Father, Son, and Holy Spirit. The Father is not the Son, the Son is not the Holy Spirit, yet each one is fully and truly God. And all three exist together eternally in loving fellowship and communion. The scriptures refer to this at different points: Mat 3:16-17; Mat 28:19; 2 Cor 13:14; 1 Pet 1:2. This loving relationship exists without altering the distinct personality of each member of the Trinity.
The Christian writer Nancy Pearcey wrote,
The balance of unity and diversity in the Trinity gives a model for human social life, because it implies that both individuality and relationship exist within the Godhead itself. God is being-in-communion. Humans are made in the image of a God who is a tri-unity – whose very nature consists in reciprocal love and communication among the Persons of the Trinity. (Total Truth, p. 132)
Therefore, the Trinity provides a model of society where unity and diversity are both present.
