By mystical theology I mean that system of religious thought which emphasises the unity between Creator and creature, though not necessarily to the extent of becoming pantheistic. Man, mystical theology asserts, has sprung from God, but has fallen away from Him through self-love. Within man, however, is the seed of divine grace, whereby, if he will follow the narrow road of self-renunciation, he may be regenerated, born anew, becoming transformed into the likeness of God and ultimately indissolubly united to God in love. God is at once the Creator and the Restorer of man's soul, He is the Origin as well as the End of all existence; and He is also the Way to that End. In Christian mysticism, CHRIST is the Pattern, towards which the mystic strives; CHRIST also is the means towards the attainment of this end. By mystical philosophy I mean that system of philosophical thought which emphasises the unity of the Cosmos, asserting that God and the spiritual may be perceived immanent in the things of this world, because all things natural are symbols and emblems of spiritual verities. As one of the _Golden Verses_ attributed to PYTHAGORAS, which I have quoted in a previous essay, puts it: "The Nature of this Universe is in all things alike"; commenting upon which, HIEROCLES, writing in the fifth or sixth century, remarks that "Nature, in forming this Universe after the Divine Measure and Proportion, made it in all things conformable and like to itself, analogically in different manners. Of all the different species, diffused throughout the whole, it made, as it were, an Image of the Divine Beauty, imparting variously to the copy the perfections of the Original."(1) We have, however, already encountered so many instances of this belief, that no more need be said here concerning it.

In fine, as Dean INGE well says: "Religious Mysticism may be defined as the attempt to realise the presence of the living God in the soul and in nature, or, more generally, as _the attempt to realise, in thought and feeling, the immanence of the temporal in the eternal, and of the eternal in the temporal_."(2) (2) WILLIAM RALPH INGE, M.A.: _Christian Mysticism_ (the Bampton Lectures, 1899), p. 5.
