The Church is not limited to its physical boundaries, but through symbolism seeks to bring the worshipper into a living relationship with the sacred metaphysical, with everything that opposes the everyday and the false.

What is the significance of the Holy Altar? What do the vestments of the priests signify? What does the Divine Liturgy reveal? Why is the Antidoron given? What does the prayer of the "Our Father" truly teach?
These and many other fundamental questions are answered in this book (which is translated into modern Greek for the first time) by the learned cleric of the 15th century, and Archbishop of Thessaloniki, Symeon, thus proving that the work of the Church is the call - the invitation, that is - to the greatest mystery of Christianity, which is the Divine Communion, the attainment of a relationship with the divine. Therefore, the Church is not presented as a building of gathering, but as a structure bridging the finite with the eternal in a new state of familiarity. That is why it is called a "temple," which means "house of God," the place of the presence of the high and the true within the constructed and the human.
