Why is Goodman Brown surprised by the people he sees in the forest?

As he travels
with the old man who resembles his grandfather, Goodman Brown is surprised to see the highly
esteemed members of the Puritan community. As he walks on a path leading deeper into the forest
primeval, his faith is shaken when he recognizes Goody Cloyse, a "Christian woman" who
was his catechism teacher, along with Deacon Gookin and the minister.

Brown is shaken by his encounter with Goody Cloyse, who is well-acquainted with the Goodman's
companionthe Devil disguised in the likeness of Goodman's grandfather. Goodman wonders how Goody
would be familiar with this man, since she represents the precepts of Puritan faith and what
Goodman has considered good and pure. Then, as he continues along the path, Brown recognizes the
voices of Deacon Gookin and the minister. They eagerly speak of the Black Sabbath that they will
attend and of the "goodly young woman to be taken into communion."

"With heaven above and Faith below, I will yet stand firm
against the devil!" cried Goodman Brown.

Shaken by
the sight of those members of his community he has known to be "famous for their special
sanctity," Goodman Brown's beliefs are destroyed when he witnesses their association with
the wicked as they pay homage to the "prince of all." Nevertheless, he feels "a
loathful brotherhood by the sympathy of what was wicked in his heart." Then, seeing his
wife, Faith, Goodman calls out to her to "resist the wicked one."

After calling to Faith, Goodman Brown suddenly finds himself alone in the forest.
Perhaps he has "fallen asleep and only dreamed a wild dream of a witch meeting." At
any rate, Brown has lost his belief in the goodness of man, and he lives the remainder of his
life in a "misery unutterable" because he has found the Puritan faith corruptible in
people he previously considered good Christians.
