1. As surely as redemption was traced back to God himself, so surely was Jesus ('ο σωτηρ 'ημων) held to be the mediator of it. Faith in Jesus was therefore, even for Gentile Christians, a compendium of Christianity. Jesus is mostly designated with the same name as God,[233] 'ο κυριος ('ημων), for we must remember the ancient use of this title. All that has taken place or will take place with reference to salvation, is traced back to the "Lord." The carelessness of the early Christian writers about the bearing of the word in particular cases,[234] shews that in a religious relation, so far as there was reflection on the gift of salvation, Jesus could directly take the place of God. The invisible God is the author, Jesus the revealer and mediator, of all saving blessings. The final subject is presented in the nearest subject, and there is frequently no occasion for expressly distinguishing them, as the range and contents of the revelation of salvation in Jesus coincide with the range and contents of the will of salvation in God himself. Yet prayers, as a rule, were addressed to God: at least, there are but few examples of direct prayers to Jesus belonging to the first century (apart from the prayers in the Act. Joh. of the so-called Leucius). The usual formula rather reads: θεω εξομολογουμεθα δια 'Ι. Χρ.—θεω δοξα διο 'Ι. Χρ.[235]

2. As the Gentile Christians did not understand the significance of the idea that Jesus is the Christ (Messiah), the designation "χριστος" had either to be given up in their communities, or to subside into a mere name.[236] But even where, through the Old Testament, one was reminded of the meaning of the word, and allowed a value to it, he was far from finding in the statement that Jesus is the Lord's anointed, a clear expression of the dignity peculiar to him. That dignity had therefore to be expressed by other means. Nevertheless the eschatological series of ideas connected the Gentile Christians very closely with the early Christian ideas of faith, and therefore also with the earliest ideas about Jesus. In the confession that God chose[237] and prepared[238] Jesus, that Jesus is the Angel[239] and the servant of God,[240] that he will judge the living and the dead,[241] etc., expression is given to ideas about Jesus, in the Gentile Christian communities, which are borrowed from the thought that he is the Christ called of God and entrusted with an office.[242] Besides, there was a very old designation handed down from the circle of the disciples, and specially intelligible to Gentile Christians, though not frequent and gradually disappearing, viz., "the Master."[243]

3. But the earliest tradition not only spoke of Jesus as κυριος, σωτηρ, and διδασκαλος, but as "'ο 'υιος του θεου", and this name was firmly adhered to in the Gentile Christian communities.[244] It followed immediately from this that Jesus belongs to the sphere of God, and that, as is said in the earliest preaching known to us,[245] one must think of him "'ως περι θεου." This formula describes in a classic manner the indirect "theologia Christi" which we find unanimously expressed in all witnesses of the earliest epoch.[246] We must think about Christ as we think about God, because, on the one hand, God had exalted him, and committed to him as Lord, judgment over the living and the dead, and because, on the other hand, he has brought the knowledge of the truth, called sinful men, delivered them from the dominion of demons, and hath led, or will lead them, out of the night of death and corruption to eternal life. Jesus Christ is "our faith", "our hope", "our life", and in this sense "our God." The religious assurance that he is this, for we find no wavering on this point, is the root of the "theologia Christi"; but we must also remember that the formula "θεος" was inserted beside "κυριος," that the "dominus ac deus," was very common at that time,[247] and that a Saviour σωτηρ could only be represented somehow as a Divine being.[248] Yet Christ never was, as "θεος," placed on an equality with the Father,[249]—monotheism guarded against that. Whether he was intentionally and deliberately identified with Him the following paragraph will shew.

4. The common confession did not go beyond the statements that Jesus is the Lord, the Saviour, the Son of God, that one must think of him as of God, that dwelling now with God in heaven, he is to be adored as προστατης και βοηθος της ασθενειας, and as αρχιερευς των προσφορων 'ημων [as guardian and helper of the weak and as High Priest of our oblations], to be feared as the future Judge, to be esteemed most highly as the bestower of immortality, that he is our hope and our faith. There are found rather, on the basis of that confession, very diverse conceptions of the Person, that is, of the nature of Jesus, beside each other,[250] which collectively exhibit a certain analogy with the Greek theologies, the naive and the philosophic.[251] There was as yet no such thing here as ecclesiastical "doctrines" in the strict sense of the word, but rather conceptions more or less fluid, which were not seldom fashioned ad hoc.[252] These may be reduced collectively to two.[253] Jesus was either regarded as the man whom God hath chosen, in whom the Deity or the Spirit of God dwelt, and who, after being tested, was adopted by God and invested with dominion, (Adoptian Christology);[254] or Jesus was regarded as a heavenly spiritual being (the highest after God) who took flesh, and again returned to heaven after the completion of his work on earth (pneumatic Christology).[255] These two Christologies which are, strictly speaking, mutually exclusive—the man who has become a God, and the Divine being who has appeared in human form—yet came very near each other when the Spirit of God implanted in the man Jesus was conceived as the pre-existent Son of God,[256] and when, on the other hand, the title, Son of God, for that pneumatic being, was derived only from the miraculous generation in the flesh; yet both these seem to have been the rule.[257] Yet, in spite of all transitional forms, the two Christologies may be clearly distinguished. Characteristic of the one is the development through which Jesus is first to become a Godlike Ruler,[258] and connected therewith, the value put on the miraculous event at the baptism; of the other, a naive docetism.[259] For no one as yet thought of affirming two natures in Jesus:[260] the Divine dignity appeared rather, either as a gift,[261] or the human nature (σαρξ) as a veil assumed for a time, or as the metamorphosis of the Spirit.[262] The formula that Jesus was a mere man (ψιλος ανθρωπος), was undoubtedly always, and from the first, regarded as offensive.[263] But the converse formulæ, which identified the person of Jesus in its essence with the Godhead itself, do not seem to have been rejected with the same decision.[264] Yet such formulæ may have been very rare, and even objects of suspicion, in the leading ecclesiastical circles, at least until after the middle of the second century we can point to them only in documents which hardly found approbation in wide circles. The assumption of the existence of at least one heavenly and eternal spiritual being beside God, was plainly demanded by the Old Testament writings, as they were understood; so that even those whose Christology did not require them to reflect on that heavenly being were forced to recognise it.[265] The pneumatic Christology, accordingly, meets us wherever there is an earnest occupation with the Old Testament, and wherever faith in Christ as the perfect revealer of God, occupies the foreground, therefore not in Hermas, but certainly in Barnabas, Clement, etc. The future belonged to this Christology, because the current exposition of the Old Testament seemed directly to require it, because it alone permitted the close connection between creation and redemption, because it furnished the proof that the world and religion rest upon the same Divine basis, because it was represented in the most valuable writings of the early period of Christianity, and finally, because it had room for the speculations about the Logos. On the other hand, no direct and natural relation to the world and to universal history could be given to the Adoptian Christology, which was originally determined eschatologically. If such a relation, however, were added to it, there resulted formulæ such as that of two Sons of God, one natural and eternal, and one adopted, which corresponded neither to the letter of the Holy Scriptures, nor to the Christian preaching. Moreover, the revelations of God in the Old Testament made by Theophanies, must have seemed, because of this their form, much more exalted than the revelations made through a man raised to power and glory, which Jesus constantly seemed to be in the Adoptian Christology. Nay, even the mysterious personality of Melchisedec, without father or mother, might appear more impressive than the Chosen Servant, Jesus, who was born of Mary, to a mode of thought which, in order to make no mistake, desired to verify the Divine by outer marks. The Adoptian Christology, that is, the Christology which is most in keeping with the self-witness of Jesus (the Son as the chosen Servant of God), is here shewn to be unable to assure to the Gentile Christians those conceptions of Christianity which they regarded as of highest value. It proved itself insufficient when confronted by any reflection on the relation of religion to the cosmos, to humanity, and to its history. It might, perhaps, still have seemed doubtful about the middle of the second century, as to which of the two opposing formulæ "Jesus is a man exalted to a Godlike dignity", and "Jesus is a divine spiritual being incarnate", would succeed in the Church. But one only needs to read the pieces of writing which represent the latter thesis, and to compare them, say, with the Shepherd of Hermas, in order to see to which view the future must belong. In saying this, however, we are anticipating; for the Christological reflections were not yet vigorous enough to overcome enthusiasm and the expectation of the speedy end of all things, and the mighty practical tendency of the new religion to a holy life did not allow any theory to become the central object of attention. But, still, it is necessary to refer here to the controversies which broke out at a later period; for the pneumatic Christology forms an essential article, which cannot be dispensed with, in the expositions of Barnabas, Clement and Ignatius, and Justin shews that he cannot conceive of a Christianity without the belief in a real pre-existence of Christ. On the other hand, the liturgical formulæ, the prayers, etc., which have been preserved, scarcely ever take notice of the pre-existence of Christ. They either comprise statements which are borrowed from the Adoptian Christology, or they testify in an unreflective way to the Dominion and Deity of Christ.

5. The ideas of Christ's work which were influential in the communities—Christ as Teacher: creation of knowledge, setting up of the new law; Christ as Saviour: creation of life, overcoming of the demons, forgiveness of sins committed in the time of error,—were by some, in conformity with Apostolic tradition and following the Pauline Epistles, positively connected with the death and resurrection of Christ, while others maintained them without any connection with these events. But one nowhere finds independent thorough reflections on the connection of Christ's saving work with the facts proclaimed in the preaching, above all, with the death on the cross and the resurrection as presented by Paul. The reason of this undoubtedly is that in the conception of the work of salvation, the procuring of forgiveness fell into the background, as this could only be connected by means of the notion of sacrifice, with a definite act of Jesus, viz., with the surrender of his life. Consequently, the facts of the destiny of Jesus combined in the preaching, formed, only for the religious fancy, not for reflection, the basis of the conception of the work of Christ, and were therefore by many writers, Hermas, for example, taken no notice of. Yet the idea of suffering freely accepted, of the cross and of the blood of Christ, operated in wide circles as a holy mystery, in which the deepest wisdom and power of the Gospel must somehow lie concealed.[266] The peculiarity and uniqueness of the work of the historical Christ seemed, however, to be prejudiced by the assumption that Christ, essentially as the same person, was already in the Old Testament the Revealer of God. All emphasis must therefore fall on this—without a technical reflection which cannot be proved—that the Divine revelation has now, through the historical Christ, become accessible and intelligible to all, and that the life which was promised will shortly be made manifest.[267]

As to the facts of the history of Jesus, the real and the supposed, the circumstance that they formed the ever repeated proclamation about Christ gave them an extraordinary significance. In addition to the birth from the Holy Spirit and the Virgin, the death, the resurrection, the exaltation to the right hand of God, and the coming again, there now appeared more definitely the ascension to heaven, and also, though more uncertainly, the descent into the kingdom of the dead. The belief that Jesus ascended into heaven forty days after the resurrection, gradually made way against the older conception, according to which resurrection and ascension really coincided, and against other ideas which maintained a longer period between the two events. That probably is the result of a reflection which sought to distinguish the first from the later manifestations of the exalted Christ, and it is of the utmost importance as the beginning of a demarcation of the times. It is also very probable that the acceptance of an actual ascensus in cœlum, not a mere assumptio, was favourable to the idea of an actual descent of Christ de cœlo, therefore to the pneumatic Christology and vice versa. But there is also closely connected with the ascensus in cœlum, the notion of a descensus ad inferna, which commended itself on the ground of Old Testament prediction. In the first century, however, it still remained uncertain, lying on the borders of those productions of religious fancy which were not able at once to acquire a right of citizenship in the communities.[268]

One can plainly see that the articles contained in the Kerygma were guarded and defended in their reality (κατ' αληθειαν) by the professional teachers of the Church, against sweeping attempts at explaining them away, or open attacks on them.[269] But they did not yet possess the value of dogmas, for they were neither put in an indissoluble union with the idea of salvation, nor were they stereotyped in their extent, nor were fixed limits set to the imagination in the concrete delineation and conception of them.[270]
