XXIX. (98) Since, therefore, he thus invisibly enters into this region of the soul, let us prepare that place in the best way the case admits of, to be an abode worthy of God; for if we do not, he, without our being aware of it, will quit us and migrate to some other habitation, which shall appear to him to be more excellently provided. (99) For if when we are about to receive kings, we prepare our houses to wear a more magnificent appearance, neglecting nothing which may give them ornament, but using every thing in a liberal and unsparing manner, having for our object that they shall have an abode pleasant to them, and in all respects suitable to their majesty; what sort of habitation ought we to prepare for the King of kings, for God the ruler of the whole universe, condescending in his mercy and lovingkindness for man to visit the beings whom he has created, and to come down from the borders of heaven to the lowest regions of the earth, for the purpose of benefiting our race? (100) Shall we prepare him a house of stone or of wooden materials? Away! such an idea is not holy even to utter; for not even if the whole earth were to change its nature and to become on a sudden gold, or something more valuable than gold, and if it were then to be wholly consumed by the skill of workmen, who should make it into porticoes and vestibules, and chambers, and precincts, and temples–not even then could it be a place worthy for his feet to tread upon, but a pious soul is his fitting abode.
XXX. (101) If therefore we call the invisible soul the terrestrial habitation of the invisible God, we shall be speaking justly and according to reason; but that the house may be firm and beautiful, let a good disposition and knowledge be laid as its foundations, and on these foundations let the virtues be built up in union with good actions, and let the ornaments of the front be the due comprehension of the encyclical branches of elementary instruction; (102) for from goodness of disposition arise skill, perseverance, memory; and from knowledge arise learning and attention, as the roots of a tree which is about to bring forth eatable fruit, and without which it is impossible to bring the intellect to perfection. (103) But by the virtues, and by actions in accordance with them, a firm and strong foundation for a lasting building is secured, in order that anything which may endeavour to separate and alienate the soul from honesty and make it such another haunt, may be powerless against so strong a defence, (104) and by means of the study of the encyclical branches of elementary education, the things requisite for the ornament of the soul are provided; for as whitewashing, and paintings, and tablets, and the arrangement of costly stones, by which men decorate not merely the walls, but even the lower parts of their houses, and all other such things as these do not contribute to strength, but only give pleasure to those who live in the house; (105) so the knowledge of the encyclical accomplishments decorates the whole habitation of the soul, while grammar investigates the principles of poetry and follows up the history of ancient events, and geometry labours at equalities according to analogy, and endeavours to remedy whatever in us is deficient in rhythm or in moderation, or in harmony, by giving us rhythm, and moderation, and harmony, by means of a polished system of music; and rhetoric aims at giving us acuteness in everything, and at properly adapting all proper interpretations to everything, claiming for itself the control of all intenseness and all the vehement affections, and again of all relaxations and pleasures, with great freedom of speech, and a successful application of the organs of language and voice.
