And this was not a natural resurrection. No; the Christian faith was born of the faith that Jesus did not remain dead, but that God raised him up again, and that this resurrection was a fact; but this did not presuppose a mere immortality of the soul in the philosophical sense (see Harnack, Dogmengeschichte, Prolegomena, v. 4). For the first Fathers of the Church themselves the immortality of the soul was not a thing pertaining to the natural order; the teaching of the Divine Scriptures, as Nimesius said, sufficed for its demonstration, and it was, according to Lactantius, a gift—and as such gratuitous—of God. But more of this later.

Christianity sprang, as we have said, from two great spiritual streams—the Judaic and the Hellenic—each one of which had arrived on its account, if not at a precise definition of, at any rate at a definite yearning for, another life. Among the Jews faith in another life was neither general nor clear; but they were led to it by faith in a personal and living God, the formation of which faith comprises all their spiritual history.

Jahwé, the Judaic God, began by being one god among many others—the God of the people of Israel, revealed among the thunders of the tempest on Mount Sinai. But he was so jealous that he demanded that worship should be paid to him alone, and it was by way of monocultism that the Jews arrived at monotheism. He was adored as a living force, not as a metaphysical entity, and he was the god of battles. But this God of social and martial origin, to whose genesis we shall have to return later, became more inward and personal in the prophets, and in becoming more inward and personal he thereby became more individual and more universal. He is the Jahwé who, instead of loving Israel because Israel is his son, takes Israel for a son because he loves him (Hosea xi. 1). And faith in the personal God, in the Father of men, carries with it faith in the eternalization of the individual man—a faith which had already dawned in Pharisaism even before Christ.

Hellenic culture, on its side, ended by discovering death; and to discover death is to discover the hunger of immortality. This longing does not appear in the Homeric poems, which are not initial, but final, in their character, marking not the start but the close of a civilization. They indicate the transition from the old religion of Nature, of Zeus, to the more spiritual religion of Apollo—of redemption. But the popular and inward religion of the Eleusinian mysteries, the worship of souls and ancestors, always persisted underneath. "In so far as it is possible to speak of a Delphic theology, among its more important elements must be counted the belief in the continuation of the life of souls after death in its popular forms, and in the worship of the souls of the dead."[13] There were the Titanic and the Dionysiac elements, and it was the duty of man, according to the Orphic doctrine, to free himself from the fetters of the body, in which the soul was like a captive in a prison (see Rohde, Psyche, "Die Orphiker," 4). The Nietzschean idea of eternal recurrence is an Orphic idea. But the idea of the immortality of the soul was not a philosophical principle. The attempt of Empedocles to harmonize a hylozoistic system with spiritualism proved that a philosophical natural science cannot by itself lead to a corroboration of the axiom of the perpetuity of the individual soul; it could only serve as a support to a theological speculation. It was by a contradiction that the first Greek philosophers affirmed immortality, by abandoning natural philosophy and intruding into theology, by formulating not an Apollonian but a Dionysiac and Orphic dogma. But "an immortality of the soul as such, in virtue of its own nature and condition as an imperishable divine force in the mortal body, was never an object of popular Hellenic belief" (Rohde, op. cit.).

Recall the Phædo of Plato and the neo-platonic lucubrations. In them the yearning for personal immortality already shows itself—a yearning which, as it was left totally unsatisfied by reason, produced the Hellenic pessimism. For, as Pfleiderer very well observes (Religionsphilosophie auf geschichtliche Grundlage, 3. Berlin, 1896), "no people ever came upon the earth so serene and sunny as the Greeks in the youthful days of their historical existence ... but no people changed so completely their idea of the value of life. The Hellenism which ended in the religious speculations of neo-pythagorism and neo-platonism viewed this world, which had once appeared to it so joyous and radiant, as an abode of darkness and error, and earthly existence as a period of trial which could never be too quickly traversed." Nirvana is an Hellenic idea.

Thus Jews and Greeks each arrived independently at the real discovery of death—a discovery which occasions, in peoples as in men, the entrance into spiritual puberty, the realization of the tragic sense of life, and it is then that the living God is begotten by humanity. The discovery of death is that which reveals God to us, and the death of the perfect man, Christ, was the supreme revelation of death, being the death of the man who ought not to have died yet did die.

Such a discovery—that of immortality—prepared as it was by the Judaic and Hellenic religious processes, was a specifically Christian discovery. And its full achievement was due above all to Paul of Tarsus, the hellenizing Jew and Pharisee. Paul had not personally known Jesus, and hence he discovered him as Christ. "It may be said that the theology of the Apostle Paul is, in general, the first Christian theology. For him it was a necessity; it was, in a certain sense, his substitution for the lack of a personal knowledge of Jesus," says Weizsäcker (Das apostolische Zeitalter der christlichen Kirche. Freiburg-i.-B., 1892). He did not know Jesus, but he felt him born again in himself, and thus he could say, "Nevertheless I live, yet not I, but Christ liveth in me."[14] And he preached the Cross, unto the Jews a stumbling-block, and unto the Greeks foolishness (I Cor. i. 23), and the central doctrine for the converted Apostle was that of the resurrection of Christ. The important thing for him was that Christ had been made man and had died and had risen again, and not what he did in his life—not his ethical work as a teacher, but his religious work as a giver of immortality. And he it was who wrote those immortal words: "Now if Christ be preached that He rose from the dead, how say some among you that there is no resurrection from the dead? But if there be no resurrection of the dead, then is Christ not risen; and if Christ be not risen, then is our preaching vain, and your faith is also vain.... Then they also which are fallen asleep in Christ are perished. If in this life only we have hope in Christ, we are of all men most miserable" (I Cor. xv. 12-19).

And it is possible to affirm that thenceforward he who does not believe in the bodily resurrection of Christ may be Christophile but cannot be specifically Christian. It is true that a Justin Martyr could say that "all those are Christians who live in accordance with reason, even though they may be deemed to be atheists, as, among the Greeks, Socrates and Heraclitus and other such"; but this martyr, is he a martyr—that is to say a witness—of Christianity? No.

And it was around this dogma, inwardly experienced by Paul, the dogma of the resurrection and immortality of Christ, the guarantee of the resurrection and immortality of each believer, that the whole of Christology was built up. The God-man, the incarnate Word, came in order that man, according to his mode, might be made God—that is, immortal. And the Christian God, the Father of Christ, a God necessarily anthropomorphic, is He who—as the Catechism of Christian Doctrine which we were made to learn by heart at school says—created the world for man, for each man. And the end of redemption, in spite of appearances due to an ethical deflection of a dogma properly religious, was to save us from death rather than from sin, or from sin in so far as sin implies death. And Christ died, or rather rose again, for me, for each one of us. And a certain solidarity was established between God and His creature. Malebranche said that the first man fell in order that Christ might redeem us, rather than that Christ redeemed us because man had fallen.

After the death of Paul years passed, and generations of Christianity wrought upon this central dogma and its consequences in order to safeguard faith in the immortality of the individual soul, and the Council of Nicæa came, and with it the formidable Athanasius, whose name is still a battle-cry, an incarnation of the popular faith. Athanasius was a man of little learning but of great faith, and above all of popular faith, devoured by the hunger of immortality. And he opposed Arianism, which, like Unitarian and Socinian Protestantism, threatened, although unknowingly and unintentionally, the foundation of that belief. For the Arians, Christ was first and foremost a teacher—a teacher of morality, the wholly perfect man, and therefore the guarantee that we may all attain to supreme perfection; but Athanasius felt that Christ cannot make us gods if he has not first made himself God; if his Divinity had been communicated, he could not have communicated it to us. "He was not, therefore," he said, "first man and then became God; but He was first God and then became man in order that He might the better deify us (θεοποιηση)" (Orat. i. 39). It was not the Logos of the philosophers, the cosmological Logos, that Athanasius knew and adored;[15] and thus he instituted a separation between nature and revelation. The Athanasian or Nicene Christ, who is the Catholic Christ, is not the cosmological, nor even, strictly, the ethical Christ; he is the eternalizing, the deifying, the religious Christ. Harnack says of this Christ, the Christ of Nicene or Catholic Christology, that he is essentially docetic—that is, apparential—because the process of the divinization of the man in Christ was made in the interests of eschatology. But which is the real Christ? Is it, indeed, that so-called historical Christ of rationalist exegesis who is diluted for us in a myth or in a social atom?
