Christians, but his Apologies are the earliest extant. They are characterized by intense Christian fervour, and they give us an insight into the relations existing between heathens and Christians in those days. His other principal writing, the Dialogue with Trypho, is the first elaborate exposition of the reasons for regarding Christ as the Messiah of the Old Testament, and the first systematic attempt to exhibit the false position of the Jews in regard to Christianity.
Many of Justin's writings have perished. Those works which have come to us bearing his name have been divided into three classes.
The first class embraces those which are unquestionably genuine, viz. the two Apologies, and the Dialogue with Trypho. Some critics have urged objections against Justin's authorship of the Dialogue; but the objections are regarded now as possessing no weight.
The second class consists of those works which are regarded by some critics as Justin's, and by others as not his. They are: 1. An Address to the Greeks; 2. A Hortatory Address to the Greeks; 3. On the Sole Government of God; 4. An Epistle to Diognetus; 5. Fragments from a work on the Resurrection; 6. And other Fragments. Whatever difficulty there may be in settling the authorship of these treatises, there is but one opinion as to their earliness. The latest of them, in all probability, was not written later than the third century.
The third class consists of those that are unquestionably not the works of Justin. These are: 1. An Exposition of the True Faith; 2. Replies to the Orthodox; 3. Christian Questions to Gentiles; 4. Gentile Questions to Christians; 5. Epistle to Zenas and Serenus; and 6. A Refutation of certain Doctrines of Aristotle. There is no clue to the date of the two last. There can be no doubt that the others were written after the Council of Nicæa, though, immediately after the Reformation, Calvin and others appealed to the first as a genuine writing of Justin's.
There is a curious question connected with the Apologies of Justin which have come down to us. Eusebius mentions
