Father Pavel Adelgeim on the Name of God

“The Name of God is the content and characteristic of every text of prayer. This means that the grace-filled power of the prayer lies in the Name of God. God abides and is revealed in His Name. By calling upon the Name of God, the one praying encounters and is united with God in His Name. Calling upon the saints by means of their names and commemorating the living and the departed also have the same meaning. The name is bound up with the person of him who bears it. By calling upon the name, we come into contact with the person of him who is being named”

Presbyter Pavel Adelgeim, The Dogma of the Church in Canons and Practise, Chapter 2.  

The Name of God in the Divine Services: Menaion

"The great weight of the stony slab and the burning of fiery flame by God’s care and forethought, and Angel swiftly changed, making the one as a weightless leaf, the other, as dewy breeze, like that which that Fourth One brought, Whom the Children beheld of old; with them thou didst cry: All-compassionate Lord, great is Thy mercy; hence, in gladness do I worship Thy holy Name, which is praised of all.”
