I don't know about hard pressed as I was a member of a SBC church for many years. In fact, I help build a couple of SBC up in this area as well as up in Maine. And I still recieve the news paper for the SBC. I don't know why they still have me on their mailing list since I made a public departure. However, I still like to keep tabs on what's going on and keeping appraised of whats happening. Certainly there are fewer SBC churches and they have to fight with other denominations for membership. It seems like the fastest growing denomination in this area is the AOG churches or Charismatic knock offs.
Why do Catholics dominate this area? Well, it has to do with a lot of History for this area. Many German immigrants originally established themselves here which is why there are large numbers Catholics, Lutherans, Amish, and Mennonites in our area. Also Catholics resupplied (so to speak) when many Irish immigrants came over during the famine in Ireland in the late 1800's. Not long after the Irish came the Italians. So large number of Catholics immigrated to this country and settled in the North East. Down south settlements originally were English and Scots and Northern Irish all with Protestant backgrounds and not as many of the Germans, Irish, Italians (Catholics) moved south when these groups immigrated. Out West Catholics numbers are due to the Hispanics living in that area. Also I've noticed that those diocese where Catholic Bishops don't water down the Catholic faith with the Liberal movement that took hold in 1962 at the Vatican II council are able to maintain Catholic Membership because they properly instruct their layity. Dioceses that do not loose their members because they aren't being faithful to Jesus Christ and the consistent teaching of the Catholic Church. And in the North East of the US there is a mixture of both types of diocese.
Does that answer your question?
