When we talk about something like “priesthood,” there is always the danger of inflated egos. We all enjoy being special, and we too easily identify our personalities with the spiritual reality which we are (hopefully) mediating.
In classes for would-be priests, my friend Josephine puts forward her “FedEx theory of the priesthood,” which I have found very helpful in countering tendencies toward inflation. The FedEx man (or woman) generally has no idea what is in a package, or why it is being sent. He simply takes it from Point A to Point B, delivering it according to instructions.
Priests are very similar: we are deliverypeople. We deliver the package (the sacraments, teaching, moments of grace, etc) according to the Spirit’s guidance, and it is not up to us to know why, or what is in it for the person receiving. We don’t glorify the FedEx man, but we are glad that he is there to deliver our book or CD or box of cookies. Likewise, there is no reason to glorify someone (or ourselves!) for being a priest, although we may be very grateful that she is present to bring us communion, or to deliver the needed word of grace.
