Only Ethiopia in Africa has had Christianity as its official religion for more than 1,500 years. Churches and monasteries were established as the Kingdom and Christianity spread to Ethiopia's south and southwest. The study was planned with an ethnographic, qualitative methodology. The researcher primarily collected textual data by transcribing and translating the "Amharic" version audio data using high-quality tape recorders. The data were analyzed using an inductive and thematic analytical technique. The study's findings demonstrated that for many centuries, the Ethiopian Orthodox Church School System served as the primary defender of traditional culture. Particularly, Ethiopia's Orthodox Church had preserved a highly structured and organized system of education from primary to higher school from the sixth century. It was discovered that the church education offers a variety of study fields (specializations) at various levels with amazing teaching-learning techniques. The philosophy of Perennialism and Existentialism serves as the primary foundation for Ethiopian Orthodox Church education. It had established a foundation and made a substantial contribution to the growth and construction of Modern Ethiopia. It also offers incredible teaching and learning characteristics that should be incorporated into the current system of scientific and math education.
