ABSTRACT
This chapter intends to introduce the reader briefly to the Exposition of the Orthodox Faith written by one of the most important Christian Arab writers of the Melkite Orthodox Church in the 11th century, namely Abdallah Ibn al-Fadl. It establishes Ibn al-Fadl's metaphysics, and defines basic theological and philosophical notions like, nature, substance and its different forms, hypostasis property the difference between substance and hypostasis, accident will, energy. The chapter explains several works from Church Fathers, like John of Damascus, Basil the Great, in addition to the aforementioned work Kitab al-burhan fi tatbit al-iman, which is incorrectly attributed to Sophronios of Jerusalem. According to Ibn al-Fadl, the Divine Names do not tend to describe the Holy Nature, because there is no name for the substance of God. Ibn al-Fadl's Exposition of the Orthodox Faith is mostly a compilation and a translation of some Church Fathers, as he himself mentions in the introduction of this work.
