This is a paper read on the theological Symposium in Regensburg (july 1979) dedicated to St. Basil. The author describes the theological positions of St. Basil in very complicated ecclesiastical and doctrinal circumstances during the IV. century.
The Author points to the struggle which St. Basil had to wage, both against the Arians and Pneumatomachoi, as well as against the Monarchianists (Sabel- lians). Theological wisdom and acumen of St. Basil and his followers, the Cappadocian Fathers, consisted in his staunch protecting of the ancient theological tradition of the Eastern Church: belief in the really existing Three Divine Hypostases together with Their unity in one nature, in the Monarchia of God the Father, from Whom the Son is generated and the Holy Spirit id proceeding. This theological definition of St. Basil's gives the explanation of the initial formula of baptism: „in the name of the Father, and of the Son, and of the Holy Spirit".
St. Basil equally corrected the weaknesses of many „Niceans” as well as of the „Orientals". His triadology became the universally endorsed theology of the Orthodox Catholic Church thrughout the ages.
