I am not a sister, but since you are so kind to ask, would you comment on the use of hieros and presbyteros in patristic texts? Does it reflect a distinction between a priest effecting a sacrament and a priest as an administrative elder?
In haste, the word hieros usually meant sacred when used by the Fathers. Presbeteros meant then and means now a priest, like the parish priest. The more usual place to find the use of hieros is in hieromonk which means a monk who is a priest or hierodeacon, a monk who is a deacon. In more ancient Greek, interestingly enough, hieros was the word for a pagan priest, not presbyteros. Help any?
