My dear brother,yes the title should be that,
because indeed all the glorious saints of the Syrian Church are also Saints to the Ethiopian Church. The most renown ones I can think of and that I have found a quick reference to I have tried to list, but the Synaxarium is vast and many are listed by regions of Syria they come from if any place is mentioned so I am limited by my lack of knowledge of these regions especially since most are written in the Ethiopian version of writing and pronouncing their names which makes it very difficult to pin down the modern day version of their names to me in this limited time of research.so I will list very few of them, and although some are not in the calendar still they are widely revered. it is not only because of the 9 saints, but it predates them, starting from our Father Abba Salama, the Ethiopian Church has been highly influenced by the Syrian Church. however we see as a result of the 9 saints the exposure broadens and the monastic tradition deepens . for instance one of the earliest manuscripts that was translated from the syriac into geez was Mezgabe haymanot/ Treasury of The Faith/ which is the work of Mar Jacob of Nisibis.a deep theological discourse , originally must have been organised and published by a member of the Jacobite Church, yet in that book it mentions the Ethiopian monastics and saints and their theological discourse.
The answer to your first question is yes they are indeed in the calendar( January 01) the three of them Saints Abba Samuel, Abba Simon and Abba Gabriel along with the history of how the monastery is founded.
Mar Jacob of Nisibis
Mor Jacob of sarug
Mar Philoxenus of Mabbug
Saint John Saba/ the Spiritual elder or Aragawi menfesawi/
The writings of the above three saints are collectively called the book of the monks/ metshafte manekosat/ in Ethiopia, beginners are advised to read Mar Philxenous, those who have reached the state of the solitary to read mar Isaac, those who have tasted sweetness, to read Aragawi menfesawi.
Saint Abba Barsoma Father of the monks of Syria
Saint Abba Aaron the Syrian
The Martyr Saint Paul the Syrian
Saint Abraham the Syrian the 62nd Archbishop of the City of Alexanderia
Saint Abba Daniel the Syrian
Saint Ladimadiyos the Syrian.
Great spiritual Elders are mentioned along with the telling of the stories of other saints, Monks renowned for their holiness such as Saints Abba Joseph the Syrian, and Abba Sisikos the Syrian.
My dear suryoyutho, I hope this has been a little bit helpful. May the Prayers of the Saints of Syria be with all the people of Syria in this time of their need. May the Prayers of all the Saints be with us all. Amen.
