The Logos of God

The Logos of God is called the door (cf. John 10:9) because He leads to spiritual knowledge those who, in their unsullied pursuit of the ascetic life, have nobly traversed the whole way of the virtues, and because He reveals, as does light, the lustrous treasures of wisdom.

For He Himself is the way, the door, the key and the kingdom.

He is the way, because He guides; He is the key, because He both opens and is opened to those found worthy to receive divine blessings; He is the door, because He gives admittance; He is the kingdom, because He is inherited and because He enters by participation into all things.
