Yeah, sorry, but the verses you quoted very neatly debunk your own thesis:
“37 As it was in the days of Noah, so it will be at the coming of the Son of Man.”
Unless you can point out where the Second Coming already happened at the time of the destruction of the temple in 70 AD... because it seems every single Christian on the planet at the time (and all the non-Christian writers as well) missed that event, which we have been told the entire world will witness.
Matthew 24:37 clearly says Jesus will usher in the age of the church - Jesus does not mention any hint of a tribulation or a millenium after His coming
the reign of Christ the King began with his earthly ministry, including the founding of his community and continues in what the Lutherans call the True Presence in the Eucharist where there is parousia.
Jesus completed the sacrifices, fulfilled the Law. Remember the work of Jesus, who in his one Sacrifice of Calvary fulfilled and thus made obsolete the Old Covenant sacrifices (Heb. 8:6-7, 13), which had to be offered at the Temple in Jerusalem.
The Letter to the Hebrews makes clear that Jesus definitively ended the need for the repetitive animal sacrifices of Temple worship, when he suffered and died once for all (Heb. 7:27). In doing so, he culminated his one Sacrifice of Calvary in everlasting glory in the heavenly sanctuary, not a mere earthly one, (Hebrews 8:1-3; 9:11-12, 23-24); and he makes that Sacrifice present on earth “as a priest forever, according to the order of Melchizedek,” (Heb. 5:6; see Heb. 5:5-10; 7:23-26;), i.e., under the appearances of bread and wine (see Gen. 14:18-20; Mt. 26:26-29).
