Abstract

The Greek model of the Trinity, based on the Theological Orations of Gregory of Nazianzus, treats the Trinitarian relations as connections between the Father and the two other persons: the Son and the Holy Spirit. The two relations have to be heteronymous, and have to be interpreted from the extreme realistic position. The Latin Trinitarian model, based on Boethius’ De Trinitate, treats relations as three subsistent persons. The relations have to be unidirectional: from the Father to the Son, and from both of them to the Holy Spirit. Both models are adequate and effective, but incompatible. One of the consequences of this incompatibility is the problem of filioque: the introduction of an additional relation of procession into the Greek model as well as the exclusion of this relation from the Latin model result in the inadequacy of the models. From the point of view of the complementability of a model, the Greek model allows introduction of new elements, while the Latin model does not. The soteriological consequences are such that the Greek model welcomes a human person to establish a unique relation with the person of the Father, which leads to the theosis of a creature. The Latin model requires the saving relation to be established with the whole Trinity, and theosis is not supported.
