Notes about Supporting a Priest
– from "Priestly Attire", an article in Orthodox Life, 1991 #1
"A priest, who is fully supported by his parish, and is given the opportunity not to work at a secular job, should have the appearance of an Orthodox priest, that is, should have long hair, a beard, a riasa, wear a cross of a proper style, and not one he has thought of himself and in his external appearance fully exemplify a true pastor."
Normally, my observation is that priests use all of their spare time for the Church, scheduling extra services on their off-days if they are employed. And some employed priests make time between working hours, scheduling midnight liturgies even when they have to be at work early the next morning. In these cases, the parish, could help by giving some support so that the priest could get by with a part-time job.
– from the Synaxaristes, November, "St. John Chrysostom" p. 510
... Saint John was also anxious that the wealthy and landed Christians should endow a church. "Many build marketplaces and baths, but no one builds a church. Everything else comes before that! Therefore I admonish you and beg you most earnestly – nay, I make it a law – that no one shall possess estates without a church ... If you have alms to give, set aside some for this. Do not tell me there is already a church in the neighborhood, or that the expense is too great. Maintain a priest and a deacon and whatever else belongs to the upkeep of a church. There you will be prayed for always."
