First, the author proves that Huss' Commentary on the Sentences, which has been for a long time neglected, played an important part in the life and works of the Czech reformer. While due attention has always been paid to Huss' ecclesiology and his teachings about the Eucharist, his Trinitarian theology has been much neglected.
The second part of the essay discusses manifestations of Trinitarian theology in the introductions to specific books. The following part provides a detailed discussion of material from I Sent, d. 1-34.
Quite understandably, Huss' Trinitarian theology exhibits some shortcomings of contemporary scholasticism: exaggerated focus on psychological theories, neglect of social and relational theories, and a certain tendency to sideline the economic Trinity. One of the discoveries of this study is Huss' openness towards Eastern approaches to Trinitarian theology, such as when he stresses not only the necessity to conceive the Son and to emanate the Spirit, but also writes about the freedom of these inter-godly realities.
Huss is open to the opinion that the Spirit emanates primarily from the Father and in derivation also from the Son, daring to disagree with the opinion of Thomas Aquinas. His thesis about the servant-like mediation of the gift of the Spirit on part of the believer is also quite surprising.
The explanation of these attitudes on Huss' part could be the contemporary opinion of Czech Masters that the Czech nation was related to Greeks.
