The woman said unto him, I know that Messiah comes, who is called Christ: when he comes, he will tell us all things.
All Commentaries on John 4:25 Go To John 4
Cyril of Alexandria
AD 444
Upon Christ teaching that the hour and season will come, rather is already present, wherein the true worshippers shall offer to God the Father the worship in spirit; forthwith the woman is winged to thoughts above her wont unto the hope spoken of by the Jews. She confesses that she knows that the Messiah will come in His own time, and to whom He will come, she does not exactly say, receiving (as is like) the common reports of Him without any investigation, as being a laughter-loving and carnal-minded woman; yet is she not wholly ignorant that He will be manifested to Israel as a bringer in of better teaching, finding most certainly this information too in the reports about Him.
