Question
What do the parts of an Orthodox church mean?
An Orthodox church is not just a building -- it is a theological diagram. Every space has a name and a meaning. The narthex is the outer vestibule, where the world ends. The nave is where the faithful stand. The sanctuary behind the iconostasis is the holy of holies. Each space is a stage in the soul's journey toward God.
The journey from the entrance to the altar is the journey from earth to heaven, from the outer life to the inner life, from catechumen to illumined. You do not rush to the altar. You approach it through its antechambers, prepared by each space along the way. The architecture is a formation -- it teaches patience, reverence, and the proper ordering of the spiritual life.
The teaching
The iconostasis -- veil and revelation
The iconostasis is the most distinctive feature of an Orthodox church. It is a screen of icons separating the nave from the sanctuary. It has three doors: the Royal Doors in the centre (through which the priest carries the Gospel and the Eucharistic gifts), and the north and south deacon's doors. The Royal Doors are opened and closed at specific moments in the Liturgy -- a theology in movement.
The icons on the iconostasis are arranged in a specific order. The bottom row always has: Christ Pantocrator to the right of the Royal Doors, the Theotokos to the left, the patron saint of the church to the right of Christ, and John the Baptist to his right. Above the Royal Doors is always the Annunciation. The second row is the Deesis -- Christ enthroned in glory, flanked by the Theotokos, John the Baptist, and the apostles in intercession.
The nave is the earth; the altar is heaven. As the priest enters the holy place, angels descend with him. The curtain that divides them is the boundary between the seen and the unseen.
The patristic reading of the iconostasis as a boundary between seen and unseen is not a statement about exclusion but about mystery. The divine reality is present everywhere in the church, but it is present in the sanctuary in a specific, concentrated way -- as the most holy place, where the Eucharist is consecrated and where the divine presence is most intensely localised. The veil marks this concentration without claiming that God is absent elsewhere.

Holy Scripture
"And the curtain of the temple was torn in two, from top to bottom."
Matthew 27:51
"In my Father's house are many rooms. If it were not so, would I have told you that I go to prepare a place for you?"
John 14:2
The Iconostasis
Why the veil between nave and sanctuary is a gift, not a barrier
Western visitors to Orthodox churches often experience the iconostasis as excluding -- you cannot see what is happening at the altar. But this is the point. The divine mystery is not a performance to be watched. It is an event to be participated in -- partly visible, partly hidden, as the divine reality always is. The iconostasis trains the worshipper to relate to God as mystery rather than spectacle.
