シリア文字
The liturgical language of the Chaldean Catholic Church is Syriac and the liturgy of the Chaldean Church is written in the Syriac alphabet. The literary revival in the early 20th century was mostly due to the Lazarist Pere Bedjan, an ethnic Assyrian Chaldean Catholic from northwestern Iran. He popularized the ancient chronicles, the lives of Assyrian saints and martyrs, and even works of the ancient Assyrian doctors among Assyrians of all denominations, including Chaldean Catholics, Syriac Orthodox, Assyrian Church of the East and Assyrian Protestants.
