From the Akathist to Jesus Conqueror of Death, composed by St. Nikolai Velimirovich on Pascha 1923 — Kontakion Nine, “The Choir of Seraphim”:

“We are the first light of Thy light and the first song of Thy voice; all the angels’ tongues together cannot express the glory and light of the seraphim, just as we seraphim cannot express Thy glory and radiance, Thou only begotten One, Beloved of the Father and the Holy Spirit. Among seraphim Thou art Seraph, among cherubim Thou art Cherub, among angels Thou art Angel, among men Thou art Man. Thou art all in all; and since Thou art all in all, Thou art servant of all and Lord of all; therefore, we who rule countless worlds below us serve in humility amid the unburning flame of the Divinity of the Trinity, carrying Thy love downward to Thy creature and the love of the creatures upward to Thee, singing the triumphant hymn: Alleluia.”

Last year for the Feast of Archangel Michael and the Other Bodiless Powers, I shared the songs that St. Nikolai gives to the Angels and Archangels. But I’m not sure I’ve posted a link to this article before: “The Divinely-Revealed Appearance of Angels in Icons.” It is so full of the mystery and glory of angels, as they reveal God’s great love toward us, that my heart was near to bursting from considering a small part of it.

This is a good day to join with cherubim, seraphim,
and all the ranks of angels as they sing
praises to the Holy Trinity.
