The divine substance as māsūra and muftaraqa. An attempt of reinterpretation of the Trinitarian terminology in the light of the teaching of Abū Rā’iṭa’s al-Risāla fī l-thālūth al-muqaddas

Abstract

The paper deals with Abū Rāi’ṭa’s Trinitarian terminology found in his al-Risāla fī l-thālūth al-muqaddas. In particular, it concentrates on an expression that epitomises the unity of the divine substance and multiplicity of hypostaseis, i.e. “māsūra and muftaraqa”. In the light of the Abū Rāi’ṭa’s understanding of the the Trinitarian doctrine, an attempt of reinterpretation of the meaning of these key-terms is presented.
