Towards a Critical Edition of the Book Al-Jāmiʿ Wujūh al-Īmān (Summa Theologiae Arabica)

As part of our research into how the Gospels and Psalms were received in the Melkite milieu, which resulted in the version published by Athanasius Dabbas in Aleppo between 1706 and 1708, we previously identified a collection of homilies written by Ibn al-Sirri in the second half of the ninth century that frequently cite both the Gospels and the Psalms (Ibrahim, 2023). We are currently preparing a critical edition of this 25,000-word collection, which will be published in the Patrimoine Arabe Chrétien series. We have also identified an 11th-century Antiochian Arabic version preserved in Sin. Ar. 76, which contains the same text as the lemmas preserved in the 'Commentaries on the Gospels of Matthew and John' by John Chrysostom, translated by Anthony. This version may be that of either Anthony or Abdallah Ibn al-Fadl (Ibrahim, 2026). Here, we present our work on “Al-Jāmiʿ wujūh al-īmān bi-tathlīth waḥdaniyyat Allāh wa-taʾannus Allāh al-kalima min al-tāhira al-ʿadhrāʾ Maryam” (The Compilation of the aspects of the faith in the Tri-unity of God and the Incarnation of God the Word from the pure one, the Virgin Mary), also known as Summa theologiae arabica (Griffith, 1986). This also answers many scholars highlighting an edition of this work as a 'desideratum' (Gibson et al., 2018: 61).
