Our fathers worshipped in this mountain. The Samaritans at that time did, as we learn from the words of the woman, what is customary with those who have revolted from true godliness, to seek to shield themselves by the examples of the Fathers. It is certain that this was not the reason which induced them to offer sacrifices there, but after that they had framed a false and perverse worship, obstinacy followed, which was ingenious in contriving excuses. I acknowledge, indeed, that unsteady and thoughtless men are sometimes excited by foolish zeal, as if they had been bitten by a gad-fly, so that when they learn that any thing has been done by the Saints, they instantly seize on the example without any exercise of judgment.
