The aim of this descriptive study was to explore the historical expansion of Christianity in the pre-Islamic Middle East, specifically focusing on the geographical area extending from Edessa to Mazun, which is situated in the southeastern corner of the Arabian Peninsula. This region encompasses present-day Oman and the United Arab Emirates. Known as Mazun in the Pahlavi language, it was referred to as 'Uman by the initial Arab tribe that migrated to this area.

The study also introduced and delved into various factors that might have contributed to the eventual disappearance of the Church of Mazun from historical records during the late seventh century. The church's presence is attested to by historical documents, but its apparent vanishing from the annals of history raises intriguing questions.
