Athenagoras finally describes the Holy Spirit, whom he identifies with
the Son who is νους σοφια,
and λογος,
as we have seen, in the following terms:
The same Holy Spirit that empowers (καιτοι και αυτο το ενεργουν) those who
proclaim prophetically (τοις εκφωνουσαι προφητικως) we say is the effluence
of God (αγιον πνευμα απορροιαν ειναι φαμεν του θεου)
which flows forth from him (απορρεον) and returns (και επαναφερομενον) like the
rays of the sun (ως ακτινα ηλιου).
Who then would not be amazed (τις ουν ουκ αν απορησαι) if he heard of men called atheists (ακουσας αθεους καλουμενους) who
bring forward God the Father, God the Son and the Holy Spirit (τους αγοντας θεον πατερα και υιον θεον και πνευμα αγιον), and who
proclaim both their power in their unity (δεικνυντας αυτων και την τν τη ενωσει δυναμιν) and their
diversity in rank (και την τη ταξει διαρεσιν).
