When Westerners enter a worship service among the Ethiopian Orthodox – as one Westerner has said – they enter an experience of “delighted disorientation… the opulent vestments, the sumptuous processional “parasols,” the grand elaborate liturgies, the ornate gold crosses, the vivid icons, the drums and sistrums and ritual dance and mesmerizing pentatonic chant.64 This spellbinding worship experience expresses a very ancient faith, practiced today as it has been for centuries in the Ethiopian Orthodox Tewahido Church. (The word Tewahido refers to “The two natures of God-head and Manhood are perfectly united and Christ is thus one person and one nature from two natures”).
Tekletsadik Belachew (Thu,) studied this question.
