According to Bible Hub,
What does amillennialism mean?
Amillennialism is an interpretive position that understands the “thousand years” mentioned in
Revelation 20 not as a future literal reign of Christ on earth lasting exactly one thousand years, but as a symbolic representation of
Christ’s current spiritual reign
Amillennialists read
Revelation 20:1-6 as depicting the spiritual reality of Christ’s reign, with “a thousand years” representing completeness or a long, unspecified period. As Revelation’s language is often apocalyptic, the focus lies on Christ’s reigning authority rather than the precise duration of a future earthly kingdom.
This might sound a little nasty, but that makes me think of a Docetic form eschatology. Instead of jumping to conclusions, it's better to ask the question: What do you mean by "spiritual" (Christ's current spiritual reign or spiritual reality of Christ's reign)? Just, so my fellow believers in Christ knows, I am a Historical Premillennialism, and we believe Christ is reigning 'right now' is physical and not spiritual according to his human nature. For instance, the 3rd Council of Constantinople (A.D. 681), states:
For in the same manner that his all-holy and spotless ensouled flesh, though divinised, was not destroyed, but remained in its own law and principle also his human will, divinised, was not destroyed, but rather preserved, as Gregory the divine says: “His will, as conceived of in his character as the Savior, is not contrary to God, being wholly divinised."
According to the Council of Constantinople that Christ’s glorified humanity is not destroyed, which is basically assert that the resurrection does not dissolve, absorb, or override the human nature but instead confirms its full ontological integrity. Nothing human is lost, replaced, or swallowed by the divine; the human nature assumed in the incarnation is the selfsame human nature raised in glory. The resurrection introduces no fusion of essences, no mixture of properties, no blurring of natures. Instead, the human nature remains genuinely human in every respective way. This condition safeguards the continuity of Christ’s human nature from Bethlehem to Calvary to resurrected from the empty tomb to the exalted at right hand of the Father and reigning with all power and authority. The risen Christ is not a divine apparition, not a symbolic presence, not a spiritualized projection. He is the same Jesus, now glorified, whose humanity remains real, intact, and fully operative.
