PHILOSOPHICAL BACKGROUND OF THE THEOLOGY OF THEODORE ABU QURRАH
O.V. DavydenkovA prominent Melkite writer Theodore Abu Qurrah, Bishop of Harran (c. 750 – c. 830) was the first Orthodox Christian author who used Arabic for his treatises. He was generally reputed both as a theologian, and a scholar well versed in philosophy. Nevertheless, the philosophical premises of his Trinitarian doctrine and Christology still remain unexplored. The article discusses two kinds of philosophical premises of Theodore’s theology: logical and ontological. Theodore divides all scientific terms and academic concepts into two groups: 1) philosophical and 2) logical names. Names of the general type such as “living being”, “human”, “horse”, and particular nonlogical ones (proper names as Paul, Jacob, John) are defined as philosophical, while such terms as “kind”, “type”, “nature”, “hypostasis”, etc. are specified as logical. According to Theodore, the crucial difference between these two types resides in the following: for philosophical type of names, the properties and definitions of more general names (concepts) are inherited by particular names; which is not true for logical names. In terms of logic, Abu Qurrah believes that the category of quantity is applicable only to logical names. Striving for the utmost accuracy of statements, he defended the theory of reference, which occurs only in one of the authors who preceded Theodore, St. Gregory of Nyssa. In terms of ontology, Theodore proceeds from the belief that the general is completely, without division and multiplication, presented in a particular (individual). Here, bringing out the conceptual differences between the hypostasis and the nature, he, meanwhile, denies that accidental attributes are origins of the hypostasis. Furthermore, the existence of particular substances (natures) seems to Theodore both logically and ontologically impossible. The ontology of the hypostasis, the fundamental principle of Theodore Abu Qurrah’s theology, seems similar to Byzantine diphysite tradition of 4th – 8th centuries (St. Leontius of Byzantium, St. Maximus the Confessor, St. John of Damascus).
