+++ Edit 07/05/2025: A statement from HE Metropolitan Youssef: https://youtu.be/5tKJn-z1i8s?si=QG8qtDM68dAi-CQ-&t=3382 Basically they are not to be prayed anymore in the Coptic Orthodox Church as per Holy Synod direction. - The Habashi Mass or Liturgy Late Fr. Istafanous Rizk (Source: http://www.youtube.com/watch?v=R0zkZzRFdOI) Bought from local Coptic Orthodox library - After some light research, this link seems to explain the source of this liturgy more (https://www.scribd.com/document/776982752/02-%D8%B1%D9%81%D8%B9%D9%86%D8%A7-%D8%A7%D9%84%D9%8A%D9%83-%D8%B9%D9%8A%D9%88%D9%86%D9%86%D8%A7-%D9%8A%D8%A7%D8%B1%D8%A8-%D8%B1%D9%81%D8%B9%D9%86%D8%A7-%D9%82%D9%84%D9%88%D8%A8%D9%86%D8%A7-%D9%88%D8%A3%D9%81%D9%83%D8%A7%D8%B1%D9%86%D8%A7) From what I understand from the above, this particular Habashi Mass is one of 14 (I think also from the Ethiopian Orthodox Church, an Ethiopian Orthodox Priest I think told me they have more than the 3 we have and it was a number in that order) and that this particular liturgy is the liturgy of 'St. John the son of Thunder (the evangelist)'. However please see edit above regarding this liturgy not being prayed anymore in the Coptic Church. +++
