The first and primary work of the Eternal Sacred Order of the Cherubim and Seraphim is that of prayer and preaching in response to the great commission of the church as recorded in the Gospel of Matthew 28:19-20

Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you: and lo, I am with you always, even unto the end of the world. Amen.
