Wikipedia is not entirely accurate here.
Futurists are not often called Millennialist (to my knowledge at least) since futurism is a broad interpretive framework whereas millennialism deals with one’s view on the 1000 year reign of Christ which Revelation speaks of.
On this point, Pre-millennialism suggests that the Jesus will return before (pre) his 1000 year reign begins.
Post-millennialism argues that things on earth will get better and better for the church until all who live at that time become Christians. This will continue for 1000 years and then Jesus will return.
Amillennialism however, suggest that the 1000 years represents the entire church age from the time of Christ’s ascension to the time of his return. That is to say, he is ruling but his rule is not yet unopposed (FWIW, this is my position). This, however, has nothing to do with how they read the rest of Revelation since that is governed by whatever interpretive framework one lands on.
I hope that provides some helpful clarity for folks. Since it was not part of the OPs question, those wanting to look at this topic a bit closer might want to pick up this resource.
For my part, I am predominantly a preterist. The letter to the seven churches (which is what revelation is) was written to specific people, in a specific place, at a specific time and so it must have made sense to them for the church to read it and preserve it. Seems strange that they would say “well Silas, it might not mean much to you now but give it 2000 years…” That said, like all the other books in the bible, I think it stills speaks to the church in all ages, places and times.
I do however hold a preterist position with a sprinkling of futurism on top. In my mind, New Creation, the final judgement, Christ’s return, etc. are all described as future events.
As always questions and comments welcome.
