The names of Clement of Rome and of Apollos have both been suggested as those of the probable author. Such opinions, however, are pure fancies, which it is perhaps impossible to refute, but which rest on nothing more than conjecture. Nor can a single word be said as to the person named Diognetus, to whom the letter is addressed. We must be content to leave both points in hopeless obscurity, and simply accept the Epistle as written by an earnest and intelli- gent Christian to a sincere inquirer among the Gentiles, towards the close of the apostolic age.
