The Holy Trinity
The basis for the doctrine of the Trinity
The central Christian affirmations about God are condensed and focused in the classic doctrine of the Trinity, which has its ultimate foundation in the special religious experience of the Christians in the first communities. This basis of experience is older than the doctrine of the Trinity. It consisted of the fact that God came to meet Christians in a threefold figure: (1) as Creator, Lord of the history of salvation, Father, and Judge, as revealed in the Old Testament; (2) as the Lord who, in the figure of Jesus Christ, lived among human beings and was present in their midst as the “Resurrected One”; and (3) as the Holy Spirit, whom they experienced as the power of the new life, the miraculous potency of the Kingdom of God. The question as to how to reconcile the encounter with God in this threefold figure with faith in the oneness of God, which was the Jews’ and Christians’ characteristic mark of distinction from paganism, agitated the piety of ancient Christendom in the deepest way. In the course of history, it also provided the strongest impetus for a speculative theology, which inspired Western metaphysics for many centuries. In the first two centuries of the Christian Era, however, a series of different answers to this question developed.
The diversity in interpretation of the Trinity was conditioned especially through the understanding of the figure of Jesus Christ. According to the theology of The Gospel According to John, the divinity of Jesus Christ constituted the departure point for understanding his person and efficacy. The Gospel According to Mark, however, did not proceed from a theology of incarnation but instead understood the baptism of Jesus Christ as the adoption of the man Jesus Christ into the Sonship of God, accomplished through the descent of the Holy Spirit. The situation became further aggravated by the conceptions of the special personal character of the manifestation of God developed by way of the historical figure of Jesus Christ; the Holy Spirit was viewed not as a personal figure but rather as a power and appeared graphically only in the form of the dove and thus receded, to a large extent, in the Trinitarian speculation.
