"This generation is an evil generation; it seeks a sign, but no sign shall be given to it except the sign of Jonah. 30 For as Jonah became a sign to the men of Nineveh, so will the Son of man be to this generation."

Luke 11:29-30

"And as the Son of God came to do the Father's will, so shall ye fulfil the will of your mother, which is the Church, the head of which, as has been stated already, is the church of Rome."

- St. Pope Callistus I
