Articles like that make me wonder what an ‘evangelical’ is.
I’ve been to a Pentecostal service. I know a few Pentecostals. Great folks. Not my style of worship but I would lump them in with evangelicals pretty quickly.
I think it means a subset of Protestants, although Catholics certainly proclaim the Gospel.
I think it doesn't mean Mormons or Messianic Jews.
I think it includes Baptists and Methodists, but maybe not Episcopalians.
This term gets thrown around a lot on TV, but is very poorly defined considering the amount of airtime the topic gets on political shows.
