The next document in probable chronological order which seems to belong to Rome is the Epistle to the Hebrews. It is much disputed by critics whether it was written in Rome or to Rome, but that it was extant there can hardly be doubted in view of the extensive quotations from it in the Epistle of Clement. It reveals a different mind from that of the Epistle to the Romans, but once more it is Jewish questions which are uppermost. The main problem is the meaning of the ritual law. Nevertheless, as in Romans, there are sufficient traces of sacramental teaching to make it clear that Christianity in Rome as in Corinth meant the sacramental cult of a saving Lord. This was the basis of everything, but the problems which arose from the attempt to work out its implications are as markedly Jewish in Rome as they are Greek in Corinth. It does not mean, of course, that there were no Greeks in Rome, any more than that there were no Jews in Corinth, but the dominating influence was Jewish in one and Greek in the other.

The Epistle to the Hebrews seems at first to be much more obviously "Pre-existent" in its Christology than the Epistle to the Romans, indeed it could well be explained on the theory that it was maintaining a Pre-existent Christology against a rival form of the same general type which identified the pre-existent Christ with an angel. But if one ask whether this would have been clear to a reader with Adoptionist principles, it can be seen that he would very easily have interpreted it in accordance with his own ideas. The question of what the Son of God was before the Incarnation is not the centre of the discussion. What is important is the function of High Priest in Heaven which he now fulfils, and this function is the consequence of his human life. It is true that in the first chapter there are phrases which are most naturally explained by "pre-existent" doctrine, but though the writer appears to be explaining the essential superiority of the Son to angels, in chapter ii. this superiority is the result of the Passion and Resurrection, and in verse 10 the divine being, "through whom and for whom are all things," is distinguished from the leader of our salvation, who is, of course, Jesus.[[8]] It is plain that this verse, difficult to understand on other lines of thought, is quite intelligible if it be interpreted in the light of that Adoptionism which, as we know from Hermas, used "Son of God" for the Holy Spirit and also for the glorified Jesus.

It is very hard not to discuss this question as though Adoptionism and Pre-existent Christology were consciously competing systems from the beginning. That is of course not true: none of these writers was consciously discussing the question. For this reason elements can be found in the Epistle to the Romans and in the Epistle to the Hebrews which are easily susceptible of an Adoptionist interpretation, and others equally indicative of Pre-existent Christology. This means that Christians at that moment had not formulated the problem. But The Shepherd of Hermas shows that in Rome an important body of Christians did become wholly Adoptionist, and if they used Romans and Hebrews, they probably interpreted the passages indicated above in agreement with their own opinions and passed over the rest—in accordance with the best tradition of Biblical commentators.

A third document is the first Epistle of Peter. If this were really written by Peter it cannot be much later in date than Romans, and would probably be earlier than Hebrews, but it seems increasingly clear that the Epistle refers to a later period, and cannot be the work of the Apostle. It is concerned in the main with the problem of persecution, and though the matter is extremely obscure, on the whole a date early in the second century in the time of Trajan and Pliny seems the most likely. Whether the indications that it comes from Rome are not part of the fiction of its authorship is at least open to question, but the point is not very important. If it be really Roman it shows traces of a further development of sacramental Christianity, but does not throw much light on its details. It has some similarity in language to Romans, but very little in the picture presented of Christianity. The central point in it is the emphasis on baptismal regeneration, which gives Christians the certainty of immortality. The eschatological expectation of the "revelation of Jesus Christ" is strongly marked, but there is no emphasis on the hope of resurrection. On one point, however, there is a close resemblance to Paul. Spirit and flesh are contrasted, and it is clearly implied that after death the Christian, like the Christ, is spirit and not flesh. It throws little light on the question of Adoptionism, for though there is nothing in it which contradicts Pre-existent Christology, there is also nothing in it which would have startled an Adoptionist.

After this[[9]] comes the first Epistle of Clement, a letter sent by the Church of Rome to the Church at Corinth. It is generally dated at the end of the first century, but there is really very little evidence, and it is curious that this date should be accepted with so little hesitation by almost all critics. It is in the main an ethical treatise, more especially on the importance of good order in the community. This teaching is based almost exclusively on the Old Testament.

There is very little in 1 Clement which throws any light on Christology or on sacraments. For the history of doctrine, in fact, 1 Clement is, considering its length, a remarkably disappointing document, but two passages are important. In 1 Clement xlii., "The Apostles received the Gospel for us from the Lord Jesus Christ, Jesus the Christ was sent from God," there is a clear statement of the supernatural claims of the apostles, but made in such a way as to imply a lower view of Christ than Nicene orthodoxy: he is the middle term between God and the apostles, and is separated from the one as clearly as from the other. The "Lord" is more than man, but is not God. The excellence of the Lord is also expressed in 1 Clement xxxvi., in words reminiscent of Hebrews. "This is the way" (i.e. the way referred to in Psalms l. 23, "The sacrifice of praise shall glorify me, and therein is a way in which I will show him the salvation of God") "beloved, in which we found our salvation, Jesus Christ, the high priest of our offerings, the defender and helper of our weakness. Through him we fix our gaze on the heights of heaven, through him we see the reflection of his faultless and lofty countenance, through him the eyes of our hearts were opened, through him our foolish and darkened understanding blossoms toward the light, through him the Master (i.e. God) willed that we should taste the immortal knowledge, 'who being the brightness of his majesty is by so much greater than angels, as he hath inherited a more excellent name.' For it is written that 'Who maketh his angels spirits, and his ministers a flame of fire.' But of his son the Master said thus, 'Thou art my Son, to-day have I begotten thee; ask of me and I will give thee the heathen for thine inheritance.'" The resemblance to Hebrews is obvious, but throws less light than might be expected on Clement's Christology. What did he think was the meaning of "To-day have I begotten thee"? The one point which comes out clearly is that the Church was regarded as an institution for the securing of the salvation offered by the death of Christ. It has a divine authority, for just as Christ came from God, so the Apostles came from Christ. It may almost be said that the Epistle has a high Ecclesiology but an undeveloped Christology.

Thus the Christianity revealed by 1 Clement suggests a Church which had accepted Jewish ethics and a Jewish hope for resurrection, and regarded Jesus as the divine messenger of God, who in turn had appointed the Apostles as the foundation of the Church. It is a very simple form of cult, and in the prayer which Clement quotes almost everything is directed towards the Father. It is Hellenised Judaism without the ceremonial law, but with a belief in Jesus and the Church.

The next document concerned with the Church of Rome is in many ways the most important. The Shepherd of Hermas is not an easy book to appreciate at first. It is a series of interviews between Hermas and various supernatural beings who give him good advice. It may be as late as 140, but many think that it is earlier. The book was written with the practical purpose of guiding rightly the Christians in Rome. There is nothing in Hermas which really contradicts anything in 1 Clement, but it supplements it in several directions. In the first place, like Clement, it attaches great importance to the Church. No salvation is possible except in the Church, and those who are and remain in it secure eternal life, or, in the phrase of Hermas himself, "live to God." The only point on which Hermas is really different is that he seems to have nothing to say about a resurrection, and apparently was content with immortality. But this may be merely an accident and cannot be pressed.

The book throws great light on the development of thought and practice in Rome, and its Christology is the most instructive example which we possess of early Adoptionism.

The evidence is so important, and Hermas is in general so little studied, that the main passage (Sim. v. 2. 1 ff.) may be quoted: "Listen to the Parable which I am going to tell you concerning Fasting. A certain man had a field, and many servants, and on part of the field he planted a vineyard. And he chose out a certain servant, who was faithful, in good esteem and honour with him, and he called him and said to him: Take this vineyard which I have planted, and fence it until I come, and do nothing more to the vineyard. And follow this order of mine and you shall have your freedom from me. And the master of the servant went abroad. Now when he had gone the servant took and fenced the vineyard, and when he had finished the fencing of the vineyard he saw that the vineyard was full of weeds. Therefore he reasoned in himself, saying: I have finished this order of the Lord; I will next dig this vineyard, and it will be better when it is dug, and having no weeds will yield more fruit, not being choked by the weeds. He took and dug the vineyard, and pulled out all the weeds which were in the vineyard. And that vineyard became very beautiful and fertile with no weeds to choke it. After a time the master of the servant and the field came, and entered into the vineyard, and seeing the vineyard beautifully fenced, and moreover, dug, and all the weeds pulled up and vines fertile, he was greatly pleased at the acts of the servant. So he called his beloved son, whom he had as heir, and his friends whom he had as counsellors, and told them what he had ordered his servant, and what he had found accomplished. And they congratulated the servant on the character which the master gave him. And he said to them: 'I promised this servant his freedom if he kept the orders which I gave him. Now he has kept my orders, and has added good work in the vineyard, and greatly pleased me. So in reward for this work which he has done I wish to make him joint-heir with my son, because, when he had a good thought he did not put it on one side, but carried it out. The son of the master agreed with this plan, that the servant should be joint-heir with the son. After a few days he made a feast and sent to him much food from the feast. But the servant took the food which was sent to him by the master, kept what was sufficient for himself, and distributed the rest to his fellow-servants. And his fellow-servants were glad when they received the food, and began to pray for him, that he might find greater favour with his master, because he had treated them thus. His master heard of all these doings, and again rejoiced greatly at his conduct. The master again assembled his friends and his son, and reported to them what he had done with the food which he had received, and they were still more pleased that the servant should be made joint-heir with his son."
