such as Epiphanius of Salamis, Basil of Caesarea, John Chrysostom and Gregory of Nyssa accept the ministry of deaconesses as a fact. The Didascalia of the Apostles is the earliest document that specifically discusses the role of deacons and deaconesses more at length. It originated in Aramaic speaking Syria during the 3rd century, but soon spread in Greek and Latin versions. In it the author urges the bishop: "Appoint a woman for the ministry of women. For there are homes to which you cannot send a deacon to their women, on account of the heathen, but you may send a deaconess ... Also in many other matters the office of a deaconess is required." The bishop should look on the man who is a deacon as Christ and the woman who is a deaconess as the Holy Spirit, denoting their prominent place in the church hierarchy. The deaconesses are also mentioned in a passage of the Council of Nicea in 325 which implies their hierarchal, consecrated or ordained status; then more clearly at the Council of Chalcedon of 451 which decreed that women should not be ordained deaconesses until they were 40 years old. The oldest ordination rite for deaconesses is found in the 5th-century Apostolic Constitutions. It describes the laying on of hands on the woman by the bishop with the calling down of the Holy Spirit for the ministry of the diaconate. A full version of the rite, with rubrics and prayers, has been found in the Barberini Codex of 780 AD. This liturgical manual provides an ordination rite for women as deaconesses which is virtually identical to the ordination rite for men as deacons. Other ancient manuscripts confirm the same rite. However some scholars such as Philip Schaff have written that the ceremony performed for ordaining deaconesses was "merely a solemn dedication and blessing." Still, a careful study of the rite has persuaded most modern scholars that the rite was fully a sacrament in present-day terms. Olympias, one of the closest friends and supporters of the Archbishop of Constantinople John Chrysostom, was known as a wealthy and influential deaconess during the 5th century. Justinian's legislation in the mid-6th century regarding clergy throughout his territories in the East and the West mentioned men and women as deacons in parallel. He also included women as deacons among those he regulated for service at the Great Church of Hagia Sophia,
