A passion-play was enacted amid the most impressive surroundings, and we need not doubt that the moral effect was beneficial and sometimes profound. When the Egyptian mysteries of Isis and Osiris were fused with the Hellenic, a type of worship was evolved which was startlingly like Christianity. A famous Egyptian text contains the promise: 'As truly as Osiris lives, shall he [the worshipper] live; as truly as Osiris is not dead, shall he not die.' The thanksgiving to Isis at the end of the _Metamorphoses_ of Apuleius is very beautiful in itself, though it is an odd termination of a licentious novel. The Hermetic literature also contains doctrine of a markedly Johannine type, as notably in a prayer to Isis: 'Glorify me, as I have glorified the name of thy son Horus.' I agree with those critics (Cumont, Zielinski, and others) who attach the 'higher' Hermetic teaching to genuinely Hellenic sources. But it is not necessary to ascribe all the higher teaching to Greece and the lower to Egypt. Much of St. Paul's theology belongs to the same circle of ideas as these mysteries. Especially important is the psychology which divides human nature into spirit, soul, and body, spirit being the divine element into which those who are saved are transformed by the 'knowledge of God'. This knowledge is a supernatural gift, which (in the _Poimandres_) confers 'deification'. St. Paul usually prefers 'Pneuma' as the name of this highest part of human nature; in the Hermetic literature it is not easy to distinguish between Pneuma and Nous, which holds exactly the same place in Neoplatonism. The notion of salvation as consisting in the knowledge of God is not infrequent in St. Paul; compare, for example, 1 Cor. xiii. 12 and a still more important passage, Phil. ii. 8-10. This knowledge was partly communicated by visions and revelations, to which St. Paul attributed some importance; but on the whole he is consistent in treating knowledge as the crown and consummation of faith. The pneumatic transformation of the personality is the centre of St. Paul's eschatology. 'Though our outward man perish, our inward man is renewed day by day.' The 'spiritual body' is the vehicle of the transformed personality; for 'flesh and blood cannot inherit the kingdom of God'. The expression 'to be born again' is common in the mystery literature.
