Heard of full preterists by any chance?

Full preterism

Full preterism differs from partial preterism in that full preterists believe that the destruction of Jerusalem fulfilled all eschatological or "end times" events, including the resurrection of the dead and Jesus' Second Coming, or Parousia, and the Final Judgment.

Other names of full preterism include:

preterism (because the term itself means "past")
consistent preterism
true preterism
hyper-preterism (a pejorative term used by opponents of preterists)
pantelism. (The term "pantelism" comes from two Greek roots: παν (pan), "everything", and τελ- (tel-), referring to completion).
Covenant Eschatology
Fulfilled Eschatology

Full preterists argue that a literal reading of Matthew 16:28 (where Jesus tells the disciples that some of them will not taste death until they see him coming in his kingdom) places the second coming in the first century. This precludes a physical second coming of Christ. Instead, the second coming is symbolic of a "judgment" against Jerusalem, said to have taken place with the destruction of the temple in Jerusalem in AD 70. For this reason, people who oppose the whole notion also call full preterism "the AD 70 doctrine" as their whole eschatology is hinged on this one event. R. C. Sproul says of full preterist Max R. King, of Ohio; "For this schema to work, the traditional idea of resurrection must be replaced with a metaphorical idea of resurrection".

Detractors of full preterism often refer to the school as hyper-preterism. Many evangelicals regard full preterism as outside of Christian orthodoxy.
