Orthodox Christianity is often reproached with being dry and abstract in its formulas. The trinitarian formula, in particular, is represented as the petrified residue of the speculations of neo-Platonism. In reality, it expresses, in scientific form, the most vital statements of the faith of those who brought together the writings of the New Testament. It proceeds from the intellectual necessity for harmonizing the religious faith of a conscious monotheism with the specific experiences which give birth to the Christian life.
Monotheism forbids believers to place their absolute confidence in anyone other than God. Entire reliance is His exclusive right. On the other hand, Christian experience shows the believer that he finds effectively his refuge in Christ, and his specifically Christian piety obliges him to place his entire confidence in Christ. This is why our fundamentally theistic dogmatics will be a dogmatics of the trinity and the incarnation, an orthodox Christian dogmatics, orthodox in the sense of ecumenical.
