The town is associated with the General Church, a particularly conservative branch of Swedenborgianism that is generally homophobic and does not let women into the ministry. It should be noted that many more liberal Swedenborgians live there, but are not often associated with the formal church.
Contrary to rumors, it is not a cult. Some believe the confusion to be based in a misleading history book about the area.
Bryn Athyn is home to a beautiful cathedral, and Glen Cairn, which is a castle turned museum.
Within this highly inbred, political community is a 'Christian' cult Church known as the New Church which spans globally and awards high paying contracts, jobs and even careers to the political elite. They follow the Swedenborgian writings, the deciphering of God's Word though the prophet Emanuel Swedenborg, a Swedish scientist, philosopher, Christian mystic, and theologian.
When compared to most Evangelical Christianities, Swedenborgianism is much more forgiving toward the Earth-based spiritualities. However, women are still subordinate, gays are still shunned, and sex before marriage/cohabitation is not tolerated.
Not very progressive although they claim to be.
On top of this all, Bryn Athyn is a Tax Free borough. All of the schools within the borough are private, belonging to the New Church. So living within Bryn Athyn is a Tax Loophole for the Philadelphia social elite.
What is the 19 of June?
It's a Cult Holiday!
