What is the conflict between John Proctor and Reverend Parris in The Crucible?

Throughout the play, both characters
challenge
each other, as Proctor ends up fighting for his life and Reverend Parris does his
best
to remain in his important position. Initially, John Proctor disagrees
with Reverend Parris's
decision to send for Reverend Hale to investigate the
use of witchcraft. Reverend Parris
believes that John Proctor is part of a
faction attempting to usurp his power and immediately
challenges him by
mentioning his unflattering Sunday service attendance. John Proctor then

begins to discuss why he doesn't support Reverend Parris and mentions that Parris only
preaches
about Hell. Proctor also views Reverend Parris as a greedy, selfish
man who is more concerned
about his wealth and status than his obligation to
serve the Lord. Proctor cannot stand that his
tithe money is spent on golden
candlesticks and even refuses to have his child baptized by
Reverend Parris.
Reverend Parris sees Proctor's adversity as an attempt to overthrow his

authority and tries to convince the Court officials that Proctor is a rogue troublemaker
who
should burn with the other witches.
