We have already seen the beginning of both the apologetic and the theological movements in the Pauline and Johannine writings of the New Testament. Let us now consider the work of the Apologists of the second century.

These defenders were all educated converts; indeed some of them, like Aristides and Athenagoras, called themselves philosophers. Naturally they did not give up their philosophic custom when they went over to Christianity, but rather applied their intellectual habit to their new faith. We should be wrong, however, in thinking that they wished to reconcile Greek philosophy and Christianity; on the contrary they wished to show that Christianity was the only true philosophy. Still all, with the exception of Tatian, treated Greek philosophy and civilization with respect and were ready to recognize God’s revelations among the Greeks as well as the Jews. They labored, however, with the fundamental antagonism between revelation and reason, and were often obliged somewhat illogically to blame Greek thinkers while praising them. Yet the sway of Hellenic philosophy was so complete and the means of defense which it furnished so powerful, that the Christians readily disregarded logical difficulties and gladly used the weapons which pagan thought had forged.

It is impossible here to distinguish in full detail the contributions of the several Apologists; we must therefore be content with a summarized statement of their positions.

First of all they accepted the historic tradition of the person, work, and teachings of Christ as authentic, and made no attempt to enlarge or diminish that tradition. They endeavored rather to present Christianity as a rational religion in such a way as to win the approval of the intellectual world. As Harnack says: “These Christian philosophers formulated the content of the Gospel in a manner which appealed to the common sense of all the serious thinkers and intelligent men of the age. Moreover, they contrived to use the positive material of tradition, including the life and worship of Christ, in such a way as to furnish this reasonable religion with a confirmation and proof that had hitherto been eagerly sought, but sought in vain.”[336]

They all set forth Christianity as a revelation from God, given in the Old Testament through the inspired prophets, who had foretold the supreme revelation in Jesus Christ. Christianity therefore was something which had existed from the beginning of the world; it was a thing which revelation had continuously attested, and which consequently was ultimate truth.[337] According to Justin not only the prophets of the Old Testament but also the Greek philosophers had borne witness to the truth and had been in a measure Christians. This power of insight and of prophecy he would ascribe in the latter case as in the former to the operation of the reason of God, a seed of which was granted to every man by nature; all therefore that was reasonable in Greek thought was due to divine inspiration. He found the cause of the Greeks’ failure to expound the whole truth in the view that man’s natural endowment was insufficient to enable him to resist the evil demons which beset him.[338] Although Athenagoras did not say that every man had within him a germ of the divine wisdom, he no less than Justin granted that the pagan poets and philosophers had known the truth in part;[339] their errors had been due to their dependence on themselves. The full truth then was to be found in revelation, which gave the Apologists the sole and sufficient warrant of their faith and the complete rule of life.

But, as I have said, the Apologists represented Christianity as the one valid philosophy. We must now examine briefly its principles.

First as to the nature of God. In dealing with this subject the Apologists used a method of thought and of expression very much like that employed by Philo and the later Platonists. They contrasted God and the world: the latter they said was created, temporal, and conditioned; the former, unconditioned, eternal, and self-existent; the material world was apprehended by the senses, God by the mind and reason alone.[340] God, therefore, to them was the One, pure spirit, unchanging, requiring nothing. It followed from this idea of God that he must be regarded as supramundane, if not transcendent. As a matter of fact, these writers were perhaps unconsciously trying to reconcile the personal attributes of God the Father, which the common Christian faith ascribed to the Godhead, and the current concept of God as a transcendent and ineffable being. A variety of expressions, too numerous to be quoted here, was employed to suggest God’s exalted and perfect nature. Furthermore God was not regarded as a passive, but as a living and active spirit, who must express himself in creations; he was therefore the First Cause, the Lord, Father, and Creator of all. The perfection of his nature made him also the source of moral good.

The complete contrast between the perfect, supramundane God and the imperfect, transient world required the Apologists, like the later pagan philosophers, to postulate some agent connecting the two, and they, like Philo and others, found this in the Logos, which to them was the operative reason of God, regarded as a person. But there is this significant fact to be noted, that the Apologists reached their views with regard to God and the Logos from a contemplation of the world itself in which they saw reason and order, and detected spiritual forces working toward good ends. Therefore they believed that the world was created and directed by God’s reason. Reflection on the chain of rational causation had led them to their conclusions. But Philo and the later Platonists we might say conceived of the Logos as a remedial being, for through his mediation they saved the perfection of God from contamination with evil matter. To the Apologists, however, matter was only an indifferent finite substance.

The Logos, as the reason of God, was identical with God in essence; but as a projection by God from himself, made for the purpose of creation and revelation, the Logos had a being distinct from God, not in essence but in number, so that he was a second God; yet at the same time the Logos, being a mode of God, God’s operative reason, was included in God; therefore no polytheistic ideas were admitted here.[341]

The Logos then was regarded as a creature and a servant of God, but he was held to be above all other creatures, being one in essence with the Divine. Moreover being created and therefore finite from the point of view of time, the Logos could enter into the finite and thus do the work of creation and revelation; by the Logos the world was made out of finite matter, and man was endowed with reason and freedom of the will. It is a striking fact, however, that with the exception of Justin, the Apologists betray comparatively little interest in the incarnation of the Logos in Jesus Christ. Their efforts were directed rather to establishing against the pagan world their claim that God is One and that the Logos is the operative reason of God which exercises his powers. Furthermore they had little or nothing to say about the Holy Spirit as a separate person, but for the most part they identified the Logos and the Spirit.[342]
