GNOSTICISM, a movement of religious syncratism (or fusion of different and previously independent beliefs), which maintained itself side by side with genuine Christianity as the latter was gradually crystallizing into the ancient Catholic Church, and which bore the strong impress of Christian influences. The movement first came into prominence in the opening years of the 2nd century; it reached its height in the 3rd quarter of that century, after which it began to wane, and from the 2nd half of the 3rd century was replaced by the closely-related and more powerful Manichaean movement. Offshoots of it, however, con tinued on into the 4th and 5th centuries and many of its ideas survived among later mystics.
In short, Gnosticism, in all its various sections, its form and its character, falls under the great category of mystic religions, which were so characteristic of the religious life of decadent antiquity. All alike boast a mystic revelation and a deeply veiled wisdom. As in many mystical religions, so in Gnosticism, the ultimate object is individual salvation, the assurance of a fortunate destiny for the soul after death. As in the others, so in this the central object of worship is a redeemer-deity who has already trodden the difficult way which the faithful have to follow.
Another characteristic feature of the Gnostic conception of the universe is the role played in almost all Gnostic systems by the seven world-creating powers. There are indeed certain exceptions; for instance, in the systems of the Valentinian schools there is the figure of the one Demiurge who takes the place of the Seven. But how widespread was the idea of seven powers, who created this lower material world and rule over it, has been clearly proved, especially by the systematic examination of the subject by Anz (Unsprung des Gnosticismus) . These Seven, then, are in most systems half-evil, half-hostile powers ; they are frequently char acterized as "angels," and are reckoned as the last and lowest emanations of the Godhead; below them—and frequently con. sidered as derived from them—comes the world of the actually devilish powers. There can scarcely be any doubt as to the origin of these seven powers; they are the seven planetary divinities, the sun, moon and five planets. They imply a fusion of Babylon ian and Persian beliefs, resulting in a degradation of the Babylon ian planetary deities into half-angelic, half-demonic beings, in finitely remote from the supreme God of light.
The origin of this figure is not far to seek. It is certainly not derived from the Persian religious system, to the spirit of which it is entirely opposed. Neither would it be correct to identify her entirely with the great goddess Ishtar of the old Babylonian religion. But there can hardly be any doubt that the figure of the great mother-goddess or goddess of heaven, who was worshipped throughout Asia under various forms and names (Astarte, Beltis, Atargatis, Cybele, the Syrian Aphrodite), was the prototype of the µiT77p of the Gnostics. The character of the great goddess of heaven is still in many places fairly exactly preserved in the Gnostic speculations. Hence we are able to understand how the Gnostic µ6T77p, the Sophia, appears as the mother of the Heb domas. The great goddess of heaven is the mother of the stars.
A parallel myth to that of the Primal Man are the accounts to be found in most of the Gnostic systems of the creation of the first man. In all these accounts the idea is expressed that so far as his body is concerned man is the work of the beings who created the world. And as the man thus formed was unable to move, but could only crawl like a worm, the supreme Power put into him a spark of life, and man came into existence.
Thus the essential part of most of the conceptions of what we call Gnosticism was already in existence and fully developed before the rise of Christianity. But the fundamental ideas of Gnosticism and of early Christianity had a kind of magnetic attraction for each other. What drew these two forces together was the energy exerted by the universal idea of salvation in both systems. Christian Gnosticism actually introduced only one new figure into the already existing Gnostic theories, namely that of the historical Saviour Jesus Christ. This figure afforded, as it were, a new point of crystallization for the existing Gnostic ideas, which now grouped themselves round this point in all their mani fold diversity. Thus there came into the fluctuating mass a strong movement and formative impulse, and the individual systems and sects sprang up like mushrooms from this soil. Above all the Gnostics represented and developed the distinctly anti-Jewish tendency in Christianity. Paul was the apostle whom they rev erenced, and his spiritual influence on them is quite unmistakable. The Gnostic Marcion has been rightly characterized as a direct disciple of Paul. Paul's battle against the law and the narrow national conception of Christianity found a willing following in a movement, the syncretic origin of which directed it towards a universal religion. St. Paul's ideas were here developed to their extremest consequences, and in an entirely one-sided fashion such as was far from his intention. In approximately all the Gnostic systems the doctrine of the seven world-creating spirits is given an anti-Jewish tendency, the god of the Jews and of the Old Testament appearing as the highest of the seven. The Demiurge of the Valentinians always clearly bears the features of the Old Testament creator-God.
The attitude of Gnosticism to the Old Testament and to the creator-God proclaimed in it had its deeper roots, as we have already seen, in the dualism by which it was dominated. With this dualism and the recognition of the worthlessness and absolutely vicious nature of the material world is combined a decided spirit ualism. The conception of a resurrection of the body, of a further existence for the body after death, was unattainable by almost all of the Gnostics, with the possible exception of a few Gnostic sects dominated by Judaeo-Christian tendencies. With the dualistic philosophy is further connected an attitude of absolute indifference towards this lower and material world, and the prac tice of asceticism. Marriage and sexual propagation are con sidered either as absolute Evil or as altogether worthless, and carnal pleasure is frequently looked upon as forbidden. Then again asceticism sometimes changes into wild libertinism. Here again Gnosticism has exercised an influence on the development of the Church by way of contrast and opposition. If here a return was made to the old material view of the resurrection (the apostolic ava.Q-raOCs Tfjs rap#a5 ), entirely abandoning the more spiritual conception which had been arrived at as a compromise by Paul, this is probably the result of a reaction from the views of Gnosticism. It was just at this point, too, that Gnosticism started a development which was followed later by the Catholic Church. In spite of the rejection of the ascetic attitude of the Gnostics, as a blasphemy against the Creator, a part of this ascetic principle became at a later date dominant throughout all Christendom. And it is interesting to observe how, e.g., St. Augustine, though des perately combating the dualism of the Manichaeans, yet after wards introduced a number of dualistic ideas into Christianity, which are distinguishable from those of Manichaeism only by a very keen eye, and even then with difficulty.
Finally, it was Gnosticism which gave the most decided im pulse to the consolidation of the Christian Church as a church. Gnosticism itself is a free, naturally-growing religion, the religion of isolated minds, of separate little circles and minute sects. The homogeneity of wide circles, the sense of responsibility engen dered by it, and continuity with the past are almost entirely lack ing in it. It is based upon revelation, which even at the present time is imparted to the individual, upon the more or less convinc ing force of the religious imagination and speculations of a few leaders, upon the voluntary and unstable grouping of the schools round the master. Its adherents feel themselves to be the isolated, the few, the free and the enlightened, as opposed to the sluggish and inert masses of mankind degraded in matter, or the initiated as opposed to the uninitiated, the Gnostics as op posed to the "Hylici" (yXctcol) ; at most in the later and more moderate schools a middle place was given to the adherents of the Church as Psychici (kyucol).
This freely-growing Gnostic religiosity aroused in the Church an increasingly strong movement towards unity and a firm and inelastic organization, towards authority and tradition. An organ ized hierarchy, a definitive canon of the Holy Scriptures, a con fession of faith and rule of faith, and unbending doctrinal dis cipline, these were the means employed. A part was also played in this movement by a free theology which arose within the Church itself, a kind of Gnosticism which aimed at holding fast whatever was good in the Gnostic movement, and obtaining its recognition within the limits of the Church (Clement of Alex andria, Origen).
It must be considered as an unqualified advantage for the further development of Christianity, as a universal religion, that at its very outset it prevailed against the great movement of Gnosticism. In spite of the fact that in a few of its later repre sentatives Gnosticism assumed a more refined and spiritual aspect, and even produced blossoms of a true and beautiful piety, it is fundamentally and essentially an unstable religious syncretism, a religion in which the determining forces were a fantastic oriental imagination and a sacramentalism which degenerated into the wildest superstitions, a weak dualism fluctuating unsteadily be tween asceticism and libertinism.
BIBLIOGRAPHY.—Of the actual writings of the Gnostics, which were Bibliography.—Of the actual writings of the Gnostics, which were extraordinarily numerous, very little has survived ; they were sacrificed to the destructive zeal of their ecclesiastical opponents. Numerous fragments and extracts from Gnostic writings are to be found in the works of the Fathers who attacked Gnosticism. Most valuable of all are the long extracts in the 5th and 6th books of the Philoso phumena of Hippolytus. The most accessible and best critical edition of the fragments which have been preserved word for word is to be found in Hilgenfeld's Ketzergeschichte des Urchristentums. One of the most important of these fragments is the letter of Ptolemaeus to Flora, preserved in Epiphanius, Haeres. xxxiii. 3-7 (see on this point Harnack in the Sitzungsberichte der Berliner Akademie, 5902, PP. • Gnostic fragments are certainly also preserved for us in the Acts of Thomas. Ilere we should especially mention the beautiful and much-discussed Song of the Pearl, or Song of the Soul, which is generally, the lgh without absolute clear proof, attributed to Bardesanes (till lately it was known only in the Syrian text; edited and translated by Bevan, Texts and Studies, v. 3, 5897; Hofmann, Zeitschrift fiir neutestamentliche Wissenschaft, iv.; for the newly-found Greek text see Acta apostolorum, ed. Bonnet, ii. 2, C. 108, p. 219) . Generally also much Gnostic matter is contained in the apocryphal histories of the Apostles. We should also mention in this connection the text on which are based the pseudo-Clementine Homilies and Recognitiones (beginning of the 3rd century) . It is, of course, already permeated with the Catholic spirit, but has drawn so largely upon sources of a Judaeo-Christian Gnostic character that it comes to a great extent within the category of sources for Gnosti cism. Complete original Gnostic works have unfortunately survived to us only from the period of the decadence of Gnosticism. Of these we should mention the comprehensive work called the Pistis Sophia, probably belonging to the 2nd half of the 3rd century, translated by C. Schmidt, Koptisch-gnostische Schriften, i. (19o5), in the series Die griechischen christlichen Schriftsteller der ersten drei Jahrhunderte. The Egyptian Gnostic texts edited by C. Schmidt, Texte u. Unter suchungen, vol. viii. (1892) and Koptische-gnostische Schriften, vol. i., probably represent an advanced stage in the decadence of Gnosticism (but see also the same writer in Sitzungsberichte der Berl. Akad. for 1896, p. 839 ff.) .
On the whole, then, for an exposition of Gnosticism we are thrown back upon the polemical writings of the Fathers in their controversy with heresy. The most ancient of these is Justin, who according to his Apol. i. 26 wrote a Syntagma against all heresies (c. A.D. 150), and also, probably, a special polemic against Marcion (fragment in Irenaeus iv. 6. 2) . Both these writings are lost. He was followed by Irenaeus, who, especially in the first book of his treatise Adversus haereses (E)Eyxov Kal avarpoirris T7)1 tkevbcoUV/OU ')'vWQEWS f3Lf3XLa E7rrvE, c. A.D. I80), gives a detailed account of the Gnostic heresies. He founds his work upon that of his master Justin, but adds from his own knowledge among many other things, notably the detailed account of Valentinianism at the beginning of the book. On Irenaeus, and probably also on Justin, Hippolytus drew for his Syntagma (begin ning of the 3rd century), a work which is also lost, but can, with great certainty, be reconstructed from three recensions of it: in the Panarion of Epiphanius (after 374), in Philaster of Brescia, Adversus haereses, and the Pseudo-Tertullian, Liber adversus ommes haereses. A second work of Hippolytus (Kara 7raac2v aipEaEWv gXeyxos) is pre served in the so-called Philosophurnena which survives under the name of Origen. Here Hippolytus gave a second exposition supple mented by fresh Gnostic original sources with which he had become acquainted in the meanwhile. These sources quoted in Hippolytus have lately met with very unfavourable criticisms. Very noteworthy references to Gnosticism are also to be found scattered up and down the Stromateis of Clement of Alexandria. Especially important are the Excerpta ex Theodoto, the author of which is certainly Clement, which are verbally extracted from Gnostic writings, and have almost the value of original sources. The writings of Origen also contain a wealth of material. In the first place should be mentioned the treatise Contra Celsum, in which the expositions of Gnosticism by both Origen and Celsus are of interest (see especially v. 61 seq. and vi. 25 seq.) . Of Tertullian's works should be mentioned: De praescrip tione haereticorum, Adversus Marcionem, Adversus Hermogenem, and finally Adversus Valentinianos (entirely founded on Irenaeus). Here must also be mentioned the dialogue of Adamantius with the Gnostics, De recta in deum fide (beginning of 4th century) . Among the followers of Hippolytus, Epiphanius in his Panarion gives much independent and valuable information from his own knowledge of contemporary Gnosticism. But Theodoret of Cyrus (d. 455) is already entirely dependent on previous works and has nothing new to add. With the 4th century both Gnosticism and the polemical literature directed against it die out. The modern literature of the subject is extensive. Here references are given to a few modern contributions where guidance to further study can be obtained. See E. F. Scott, articles "Gnosticism" and "Valentinianism" in Hastings, Encyclopaedia of Religion and Ethics, and A. S.
