Russian Orthodox Chant: the Cherubikon, Cherubic Hymn or Chant. The hymn symbolically incorporates those present at the liturgy into the presence of the angels gathered around God's throne.
I love this moment when I am at the Liturgy. It’s solemn and glorious and gives a feeling as if angels are presenting at the worship.
Performers: Festal Choir of St. Elizabeth Monastery, Minsk, Belarus
Conductor: Nun Irina (Denisova)
