How we cite our quotes:
Religiously, we’re eighty-five per cent Protestants; twelve per cent Catholics; rest, indifferent. (I.225)
Grover’s Corners’ occupants are mostly Christian.
I never told you about that letter Jane Crofut got from her minister when she was sick. He wrote Jane a letter and on the envelope the address was like this: It said: Jane Crofut; The Crofut Farm; Grover’s Corners; Sutton County; New Hampshire; United States of America…Continent of North America; Western Hemisphere; the Earth; the Solar System; the Universe; the mind of God – that’s what it said on the envelope. (I.441-3)
Grover’s Corners is described as being in the "mind of God."
The real hero of this scene isn’t on the stage at all, and you know who that is. It’s like what one of those European fellas said: Every child born into the world is nature’s attempt to make a perfect human being. Well, we’ve seen nature pushing and contriving for some time now. We all know that nature’s interested in quantity; but I think she’s interested in quality, too, - that’s why I’m in the ministry. (II.298)
The passage above is a discussion of nature rather than religion. The implication is that marriage is natural for two people.
