In the Eastern Christian churches (Eastern Orthodox Church and Eastern Catholic Churches), an archdeacon is the senior deacon within a diocese and has responsibility for serving at hierarchical services (those at which the bishop is present and presiding). He has responsibility for ensuring the smooth running of the service by directing the clergy and servers as appropriate. As such, he usually travels with the ruling bishop to various parts of the diocese, and will sometimes act as his secretary and cell attendant, ensuring that he is able to balance his monastic life with his hierarchical duties. The archdeacon wears the double orarion, which is twice the length of the usual orarion, and wraps under the right arm as well as hanging from the left shoulder. An archdeacon may come from either the monastic or married clergy.
