In his commentary on Gregory of Nyssa’s
Adversus Macedonianos, Piet Hein Hupsch highlights the carefully composed structure of this work and the important connection between its theological, rhetorical and stylistic elements. In his capacity of
arbiter fidei, which was bestowed upon him by the Council of Constantinople in 381, Bishop Gregory wrote this circular letter in the form of a counteraccusation against the Pneumatomachi, developing his Trinitarian theology of adoration in which the Spirit occupies a central role.
In a systematic-theological synthesis of this work, Hupsch shows how the Spirit draws baptised human beings and human language into the relatio of the three divine persons, the dynamic circle of divine glory of which the Spirit is the personification.
