  The very structure of the church reflects the different roles of the clergy and the laity. The hierarch stands still at the altar, facing away from the multiplicity of the church’s interior. He enters the nave of the church only to bring sacred objects like incense, bread and wine, and holy oil into the realm of multiplicity, the spatially extended nave. When he brings the censer into the nave, for example, its fragrance is distributed to the laity there, just as the bread and wine are later distributed in the eucharistic rite. The hierarch then returns to the altar, and takes up again his own proper object of contemplation, the intelligible source of the rites. The laity, on the other hand, remain within the spatially extended nave, but orient themselves toward the altar, where the sacred objects are raised for their contemplation. Before this contemplation can occur, the catechumens, penitents, and the demon-possessed must be removed from the church. Their orientation toward the material prevents them from adequately contemplating the intelligible truth through its visible manifestation in the sacred objects.
