Philo interprets the stories of Torah as elaborate metaphors and symbols. He does not reject the subjective experience of Ancient Judaism; yet, he repeatedly explains that the Torah cannot be understood as a concrete, objective history. Philo is largely shaped by contemporary Greek philosophy. For example, he explains that ideal Greek forms for reason and wisdom illustrate the deep, mystical truth of God and Judaism.
Philo states his theology both through the negation of opposed ideas, and through detailed, positive explanations of the nature of God. In his negative statement, he contrasts the nature of God with the nature of the physical world. He integrates select theology from the dominant Jewish tradition, including God's sublime transcendence, and man's inability to behold an ineffable God. However, he significantly disagrees with predominant Jewish theology that God actively changes the world, is filled with zeal, is moved by repentance, and aids His chosen people.
Philo does not consider God similar to heaven, the world, or man; God exists neither in time nor space; He has no human attributes or emotions. Indeed, God has no attributes (ἁπλοῡς), in consequence no name (ἅρρητος), and for that reason he cannot be perceived by man (ἀκατάληπτος). Further, God cannot change (ἅτρεπτος): He is always the same (ἀἱδιος). He needs no other being (χρήζων ὁυδενòς τò παράπαν), and is self-sufficient (ἑαυτῷ ἱκανός). God can never perish (ἅφθαρτος). He is the simply existent (ó ὤν, τὺ ὅν), and has no relations with any other being (τὸ γὰρ ἢ ὄν ἒστιν ουχὶ τῶν πρός τι).
Philo characterizes as a monstrous impiety the anthropomorphism of the Bible, which, according to the literal meaning, ascribes to God hands and feet, eyes and ears, tongue and windpipe. Scripture, he says, adapts itself to human conceptions (ib.); and for pedagogic reasons God is occasionally represented as a man. The same holds good also as regards God's anthropopathic attributes. God as such is untouched by unreasonable emotions, as appears, e.g., from Exodus ii. 12, where Moses, torn by his emotions, perceives God alone to be calm. He is free from sorrow, pain, and all such affections. But He is frequently represented as endowed with human emotions; and this serves to explain expressions referring to His repentance.
Similarly God can not exist or change in space. He has no "where" (πού, obtained by changing the accent in Gen. iii. 9: "Adam, where [ποῡ] art thou?"), is not in any place. He is Himself the place; the dwelling-place of God means the same as God Himself, as in the Mishnah = "God is" (comp. Freudenthal, "Hellenistische Studien," p. 73), corresponding to the tenet of Greek philosophy that the existence of all things is summed up in God.
God as such is motionless, as the Bible indicates by the phrase "God stands. It was difficult to harmonize the doctrine of God's namelessness with the Bible; and Philo was aided here by his imperfect knowledge of Greek. Not noticing that the Septuagint translated the divine name Yhwh by Κύριος, he thought himself justified in referring the two names Θεός and Κύριος to the two supreme divine faculties.
Philo's transcendental conception of the idea of God precluded the Creation as well as any activity of God in the world; it entirely separated God from man; and it deprived ethics of all religious basis. But Philo, who was a pious Jew, could not accept the un-Jewish, pagan conception of the world and the irreligious attitude which would have been the logical result of his own system; and so he accepted the Stoic doctrine of the immanence of God, which led him to statements opposed to those he had previously made. While he at first had placed God entirely outside of the world, he now regarded Him as the only actual being therein. God is the only real citizen of the world; all other beings are merely sojourners therein. While God as a transcendent being could not operate at all in the world, He is now considered as doing everything and as the only cause of all things. He creates not only once, but forever. He is identical with the Stoic "efficient cause." He is impelled to activity chiefly by His goodness, which is the basis of the Creation. God as creator is called Θεός. This designation also characterizes Him in conformity with His goodness, because all good gifts are derived from God, but not evil ones. Hence God must call upon other powers to aid Him in the creation of man, as He can have nothing to do with matter, which constitutes the physical nature of man: with evil He can have no connection; He can not even punish it. God stands in a special relation to man. The human soul is God's most characteristic work. It is a reflex of God, a part of the divine reason, just as in the system of the Stoics the human soul is an emanation of the World-Soul. The life of the soul is nourished and supported by God, Philo using for his illustrations the figures of the light and the fountain and the Biblical passages referring to these.
This doctrine, as worked out by Philo, was composed of very different elements, including Greek philosophy, Biblical conceptions, pagan and late Jewish views. The Greek elements were borrowed partly from Platonic philosophy, insofar as the divine powers were conceived as types or patterns of actual things ("archetypal ideas"), and partly from Stoic philosophy, insofar as those powers were regarded as the efficient causes that not only represent the types of things, but also produce and maintain them. They fill the whole world, and in them are contained all being and all individual things ("De Confusione Linguarum," § 34 [i. 431]). Philo endeavored to harmonize this conception with the Bible by designating these powers as angels ("De Gigantibus," § 2 [i. 263]; "De Somniis," i. 22 [i. 641 et seq.]), whereby he destroyed an essential characteristic of the Biblical view. He further made use of the pagan conception of demons (ib.). And finally he was influenced by the late Jewish doctrine of the throne-chariot, in connection with which he in a way detaches one of God's fundamental powers, a point which will be discussed further on. In the Haggadah this fundamental power divides into two contrasts, which modify each other.
In the same way Philo contrasts the two divine attributes of goodness and power (ἄγαθότης and ἀρχή, δίναμις χαριστική and συγκολαστική). They are also expressed in the names of God; but Philo's explanation is confusing. "Yhwh" really designates God as the kind and merciful one, while "Elohim" designates him as the just one. Philo, however, interpreted "Elohim" (LXX. Θεός) as designating the "cosmic power"; and as he considered the Creation the most important proof of divine goodness, he found the idea of goodness especially in Θεός. On the parallel activity of the two powers and the symbols used therefor in Scripture, as well as on their emanation from God and their further development into new powers, their relation to God and the world, their part in the Creation, their tasks toward man, etc., see Siegfried, "Philo," pp. 214-218. Philo's exposition here is not entirely clear, as he sometimes conceives the powers to be independent hypostases and sometimes regards them as immanent attributes of the Divine Being.
There are, in addition, Biblical elements: there are Biblical passages in which the word of Yhwh is regarded as a power acting independently and existing by itself, as Isa. lv. 11; these ideas were further developed by later Judaism in the doctrines of the Divine Word creating the world, the divine throne-chariot and its cherub, the divine splendor and its shekinah, and the name of God as well as the names of the angels; and Philo borrowed from all these in elaborating his doctrine of the Logos. He calls the Logos the "archangel of many names," "taxiarch" (corps-commander), the "name of God," also the "heavenly Adam, the "man, the word of the eternal God."
The Logos is also designated as "high priest," in reference to the exalted position which the high priest occupied after the Exile as the real center of the Jewish state. The Logos, like the high priest, is the expiator of sins, and the mediator and advocate for men: ἱκέτης, and παράκλητος.
From Alexandrian theology Philo borrowed the idea of wisdom as the mediator; he thereby somewhat confused his doctrine of the Logos, regarding wisdom as the higher principle from which the Logos proceeds, and again coordinating it with the latter.
In its relation to the world the Logos appears as the Universal substance on which all things depend; and from this point of view the manna (as γενικώτατόν τι) becomes a symbol for it. The Logos, however, is not only the archetype of things, but also the power that produces them, appearing as such especially under the name of the Logos τομεύς ("the divider"). It separates the individual beings of nature from one another according to their characteristics; but, on the other hand, it constitutes the bond connecting the individual creatures, uniting their spiritual and physical attributes. It may be said to have invested itself with the whole world as an indestructible garment. It appears as the director and shepherd of the things in the world insofar as they are in motion.
The Logos has a special relation to man. It is the type; man is the copy. The similarity is found in the mind (νοῡς) of man. For the shaping of his nous, man (earthly man) has the Logos (the "heavenly man") for a pattern. The latter officiates here also as "the divider" (τομεύς), separating and uniting. The Logos as "interpreter" announces God's designs to man, acting in this respect as prophet and priest. As the latter, he softens punishments by making the merciful power stronger than the punitive. The Logos has a special mystic influence upon the human soul, illuminating it and nourishing it with a higher spiritual food, like the manna, of which the smallest piece has the same vitality as the whole.
