Opening Prayer of the Divine Liturgy of St. John Chrysostom
Blessed is the Kingdom of the Father and of the Son, and of the Holy Spirit, now, and always and forever and ever. Amen.
Now, you have to be there to FEEL it. The priest sings, blesses, there are candles, incense, and the entire congregation responds with a sung Amen. It's big, and the senses are engaged!
Immediately following this opening is this petition.
Notice the last prayer in the petition :
For to Thee is due all glory, honor, and adoration, to the Father and the Son, and to the Holy Spirit, now and always, and forever and ever. Amen.
One thing to note. Every time the Father, Son and Holy Spirit are mentioned during Liturgy, the congregation makes a reverant sign of the cross. Every time. It becomes almost like breathing after a while. Lovely.
