The book consists of two parts: The first part comprises a study in the extent of a monograph including five chapters on Victorinus´ life, the work of his pagan period, the Arian controversy, Victorinus´ theological work and problem of its philosophical sources. The second part comprises the Latin text and Czech translation of Victorinus´ writing "Against Arius Ib" ("On Consubstantiality of the Trinity") with an exposition of its content and a comprehensive commentary.
