Is John Proctor a Christian?

The play also shows a John Proctor who is conflicted about
his faith.  There is the issue with Reverend Parris and the money he spends on gold
candlesticks.  As the witch trials heat up, especially since he knows the truth, he
loses faith in some of the church elders and the court, because they cannot see the
farce for what it is.

I don't think Proctor ever abandons
Christianity, per se, but without saying so, he may have abandoned Puritanism by the
end.  But then again, so did a lot of people at that time.  By 1730, a mere 38 years
after the Salem fiasco, there was no Puritan Church left in New
England.
