Tertullian

In like manner (the heretic) will be refuted also with the word "man: " "The first man is of the earth, earthy; the second man is the Lord from heaven." Now, since the first was a man, how can there be a second, unless he is a man also? Or, else, if the second is "Lord," was the first "Lord" also? It is, however, quite enough for me, that in his Gospel he admits the Son of man to be both Christ and Man; so that he will not be able to deny Him (in this passage), in the "Adam" and the "man" (of the apostle).
