Whosoever wishes to see Jesus the Son of David must believe in Him; through the Virgin’s birth. He who will not believe this will not hear from Him the salutation, “Thy faith hath saved thee.” And so he will remain blind, falling into Antithesis after Antithesis, which mutually destroy each other, just as “the blind man leads the blind down into the ditch.”
Tertullian
The Five Books Against Marcion, Book IV
Chapter XXXVI
