Rabbula (Latin: Rabula) was a bishop of Edessa from 411 to August 435 AD, noteworthy for his opposition to the views of Theodore of Mopsuestia and Nestorius.
[1] The text was first translated from Syriac into English and published by J. J. Overbeck in his S. Ephraemi Syri Rabulae Episcopi Edesseni Balaei Aliorumque opera selecta (1865).
[2] He was a native of Qinnasrin, ancient Chalcis ad Bellum, a town some few miles south of Aleppo and the seat of a bishopric.
With all the energy of his fiery nature he threw himself into the practice of Christian asceticism, sold all his possessions, and separated from his wife and kinspeople.
On the death of Diogenes, bishop of Edessa, in the year 411-412 Rabbula was chosen his successor, and at once accepted the position offered him, without any of the customary show of reluctance.
As a bishop Rabbula was marked by extraordinary energy, by the continued asceticism of his personal life, by his magnificent provision for all the poor and suffering in his diocese, by his care for discipline among the clergy and monks who were under his authority, and by the fierce determination with which he combated all heresies and especially the growing school of the followers of Nestorius.
On one occasion he visited Constantinople and there preached before Theodosius II (who was then favorable to Nestorius) and a great congregation a sermon in denunciation of Nestorian doctrine, of which a portion survives in the Syriac version.
