Is it Episcopal or Episcopalian?

You may have heard reporters refer to Episcopalian bishops and the Episcopalian Church. But here's how it should work. Episcopal is an adjective (She is an Episcopal priest). Episcopalian is a noun referring to a member of the Episcopal Church (She is an Episcopalian). An Episcopalian can be a minister, in the sense of ministering to others, and this can be either a lay or an ordained ministry. Priests are usually referred to as the Reverend So-and-So, not Reverend So-and-So. (And they're generally addressed as Father So-and-So, not Reverend that's like addressing a judge as Honorable.) Bishops are usually the Right Reverend So-and-So, and addressed as Bishop So-and-So. Bishops can be identified because they wear purple. Bishops are important in the Episcopal Church.
