Saints Basil, Gregory the Theologian and John Chrysostom (the 'Golden-mouth') are celebrated today in the Byzantine rite. All three wrote Divine Liturgies which are in use in the Church today after 1700 years.
Which was divinely taught by hearing your voice
Expounding the nature of creatures,
Ennobling the manners of men.
O holy father of a royal priesthood,
Entreat Christ God that our souls may be saved.
You were revealed as the sure foundation of the Church,
granting all mankind a lordship which cannot be taken away,
sealing it with your precepts,
venerable Basil, revealer of heaven.
The shepherd's pipe of thy theology conquered the philosophers' trumpets; for since thou didst search out the depths of the Spirit, beauty of speech was added to thee. Intercede with Christ our God that our souls may be saved, O Father Gregory.
Grace like a flame shining forth from thy mouth has illumined the universe, and disclosed to the world treasures of poverty and shown us the height of humility. And as by thine own words thou teachest us, Father John Chrysostom, so intercede with the Word, Christ our God, to save our souls.
