Church Fathers on John 4:20

The woman is not offended at Christ’s rebuke. She does not leave Him, and go away. Far from it: her admiration for Him is raised: The woman said to Him, Sir, I perceive that you are a Prophet: as if she said, Your knowledge of me is unaccountable, you must be a prophet.

The husband was beginning to come to her, though He had not yet fully come. She thought our Lord a prophet, and He was a prophet: for He says of Himself, A prophet is not without honor, save in his own country.

Or thus; The Samaritans regarded Mount Gerizim, near which Jacob dwelt, as sacred, and worshipped upon it; while the sacred place of the Jews was Mount Sion, God’s own choice. The Jews being the people from whom salvation came, are the type of true believers; the Samaritans of heretics. Gerizim, which signifies division, becomes the Samaritans; Sion, which signifies watch-tower, becomes the Jews.
