People come to New York for many reasons and many choose to stay. In the 1600’s the Dutch called the new English speaking immigrants Yankees. It’s the original insult transformed into the name for people who call the greatest city in the world their home. Anyone can become a Yankee. Some were raised in an old Anglo-American, Yankee Protestant pattern of conduct. Some adopt it. Both become Yankees. In this tradition a metaphysical identity is coded in manners, and manners can be learned so deeply they become hard to separate from who a person seems to be.
If the pattern could not be learned, it would only be ancestry, and ancestry is not a church. Call the inheritance by its historical name if you need one. We use it as a discipline. There is no blood test at the door. There is a prayer book, and a way of behaving that does not embarrass the room.
