As soon as the bread and wine are set upon the alter they show forth a symbol of the death of the Son, also of His resurrection; wherefore that Spirit which raised Him from the dead comes down now and celebrates the Mysteries of the resurrection of His Body.
-St. Narsai Harp of the Spirit
Then he prepares the people with an exhortation, and says: Let your minds be aloft in this hour where King Messiah is sitting on the right hand. Be not taken up with vain thoughts of earthly things: Look upon Him that is now mystically slain upon the alter, who sits in the heights and ask mercy for sinners.
-St. Narsai Harp of the Spirit (An Exposition of the Mysteries)
The adorable alter is a symbol of that throne of the Great and Glorious, upon which He will be seen by watchers and men in the day of His revelation.
