The priest is leading the faithful in a procession to the Father. Since he is leading the procession, his face cannot be seen. Furthermore, in this perfect act of worship, the priest represents Christ the head as the faithful assembled represent Christ the body. We have no photographs of Christ but we know he is a man. Thus the priest, a man, is the symbol of Christ leading us in a procession to the Father. In persona Christi, the personality of the priest matters little. He is the faceless man, not drawing attention to himself but leading the faithful to the One being worshipped..
