In the name of the Father and of the Son and in the name of the Holy Ghost. Amen.
Gurdjieff’s formulation “In the name of the Father and of the Son and in the name of the Holy Ghost. Amen” is not, as he suggests, how this is usually formulated. The traditional Christian formulation comes from The New Testament where it is written:
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
In more recent English versions of The New Testament “Holy Spirit” is preferred to Gurdjieff’s “Holy Ghost.”
The inexactitude is in Gurdjieff’s insertion of “and in the name of.” Google this and you will not find Gurdjieff’s formulation anywhere in English except in the text of The Tales. He is clearly emphasizing the Holy Ghost.
