ብርሃኑ አድማስ፤ በዓላት፤ ምን? ለምን? እንዴት?፣ አዲስ አበባ፣ ማኅበረ ቅዱሳን፣ 1999 ዓ.ም.

This is a book on the significance of religious feasts in the context of the Ethiopian Orthodox Tewahido Church, published in 2007, with 228 pages. The author Berhanu Admas dedicates the first part of his book on the meaning of feasts and on the celebrations of the Old Testament. The second part deals with the feasts of the New Testament as they are celebrated in the Ethiopian Orthodox Tewahido Church. The major Christological feasts as well as feasts of Mary and of saints are described. Part three is focused on canonical issues with regard to days of celebration and the place of work in connection with the feasts. The last chapter discusses things to be improved with regard to the harmony between work and religious holidays but also contends criticisms of religious feasts that may reduce the time of work, from organizations outside the Ethiopian Orthodox Tewahido Church.
