33 Since God then bears witness, and the Holy Ghost joins in the witness, and Christ says, Why do you seek to kill me, a man who has told you the truth? Let the heretics be silenced who speak against His humanity, for they speak against Him, who says, Handle me, and see; for a spirit has not flesh and bones, as you see me have. Adored be the Lord the Virgin-born, and let Virgins acknowledge the crown of their own state: let the order also of Solitaries acknowledge the glory of chastity for we men are not deprived of the dignity of chastity. In the Virgin's womb the Saviour's period of nine months was passed: but the Lord was for thirty and three years a man: so that if a virgin glories because of the nine months, much more we because of the many years.
