Any one can predict regular occurrences which always take place. Accordingly, a part of what was predicted had to be irrational. Every particular in the history of Christ has therefore a significance, not as regards the future, but as regards the past. Here everything happened "that the word of the prophet might be fulfilled." Because the prophet had said so, it had to happen. Christ's destiny attests the ancient teachings of the prophets. Everything, however, depends on this attestation, for it was no longer the full truth that was wanting, but a convincing proof that the truth was a reality and not a fancy.[449] But prophecy testifies that Christ is the ambassador of God, the Logos that has appeared in human form, and the Son of God. If the future destiny of Jesus is recorded in the Old Testament down to the smallest particular, and the book at the same time declares that this predicted One is the Son of God and will be crucified, then the paying of divine honours to this crucified man, to whom all the features of prophecy apply, is completely justified. The stage marked by Christ in the history of God's revelation, the content of which is always the same, is therefore the highest and last, because in it the "truth along with the proof" has appeared. This circumstance explains why the truth is so much more impressive and convinces more men than formerly, especially since Christ has also made special provision for the spread of the truth and is himself an unequalled exemplification of a virtuous life, the principles of which have now become known in the whole world through the spread of his precepts. These statements exhaust the arguments in most of the Apologies; and they accordingly seem neither to have contemplated a redemption by Christ in the stricter sense of the word, nor to have assumed the unique nature of the appearance of the Logos in Jesus. Christ accomplished salvation as a divine _teacher_, that is to say, his teaching brings about the [Greek: allage] and [Greek: epangoge] of the human race, its restoration to its original destination. This also seems to suffice as regards demon rule. Logically considered, the individual portions of the history of Jesus (of the baptismal confession) have no direct significance in respect to salvation. Hence the teachings of the Christians seem to fall into two groups having no inward connection, i.e., the propositions treating of the rational knowledge of God, and the predicted and fulfilled historical facts which prove those doctrines and the believing hopes they include.
