Deacons

In the Syriac Orthodox tradition, different ranks among the deacons are specifically assigned with particular duties. The ranks of diaconate are:

1. Shamosho (High Deacon)
2. Afudyaqno (Sub-deacon)
3. Quroyo (Reader)
4. Mzamrono (Singer)

Only a full deacon or Masamsono can take the censer during the Divine Liturgy to assist the priest. However, in Malankara Syriac Orthodox Church, because of the lack of deacons, altar assistants who do not have any rank of deaconhood may assist the priest. The deacons in Malankara Syriac Orthodox Church are allowed to wear a phiro, a cap. Historically the Malankara Church were administered by a local chief called Archdeacon ("Arkadiyokon").
