How is the Devil's service and congregation described in "Young Goodman Brown"?

When Goodman
Brown calls the devil by saying "come devil himself!" it seems that he gets what he
asks for.The forest appears to him to be ablaze with a red light, and he hears sounds that
resemble a hymn but resolve to "sounds of the benighted wilderness."

As Brown moves closer to the service, he sees a stone that functions as an altar or
pulpit, and four trees with flaming tops. The clearing in the woods is surrounded by burning
foliage. The congregation that Brown sees assembled, are to him "grave and dark-clad
company" comprised of people he recognizes from his own Christian congregation and people
from Salem "famous for their especial sanctity." Deacon Gookin is there, accompanied
by Brown's pastor.His catechism teacher, Goody Cloyse is there along with the fallen people of
his village, and Indians are also in attendance. The congregation is large.
