Just one small question, without being arbitrary, how does the Day of Atonement fit with this fall feasts and the Second Coming theory?
You seem to call out Trumpets while ignoring Yom Kippur.
The imagery and typology of Yom Kippur certainly seems to be tied to Christ's first coming when He actually accomplished the work of atoning for the sins of His people.
"For on that day the priest shall make atonement for you, to cleanse you, that you may be clean from all your sins before the Lord. ... then he shall make atonement for the Holy Sanctuary, and he shall make atonement for the tabernacle of meeting and for the altar, and he shall make atonement for the priests and for all the people of the assembly. " (Lev. 16:30,33)
"And she will bring forth a Son, and you shall call His name Jesus, for He will save His people from their sins." (Matt. 1:21)
Christ has made sacrifice for His "holy Sanctuary" and "the people of the assemply" (the church). Nothing at the second coming will contribute to that atonement accomplished and applied.
"And for this cause He is the mediatory of a new covenant, in order that, death having taken place for the propitiation of the transgressions under the first covenant, they which have been called may receive the promise of the eternal inheritance." (Heb. 9:15)
Explaining that is a whole article in and of itself, which I intend to have out in about ten days and which I'll be happy to ping you to--along with any of the rest of the GRPL who are interested in being pinged.
I'm not ignoring either Yom Kippur or Sukkot--I'm just focusing on Yom Teruah in this particular article.
Chapter 16 The Day of Atonement
The Goat Shown to the People
The lot having designated each of the two goats, the high-priest tied a tongue-shaped piece of scarlet cloth to the horn of the goat for Azazelthe so-called scape-goatand another round the throat of the goat for Jehovah, which was to be slain. The goat that was to be sent forth was now turned round towards the people, and stood facing them, waiting, as it were, till their sins should be laid on him, and he would carry them forth into a land not inhabited. Assuredly a more marked type of Christ could not be conceived, as He was brought forth by Pilate and stood before the people, just as He was about to be led forth, bearing the iniquity of the people. And, as if to add to the significance of the rite, tradition has it that when the sacrifice was fully accepted the scarlet mark which the scape-goat had borne became white, to symbolise the gracious promise in Isaiah 1:18; but it adds that this miracle did not take place for forty years before the destruction of the Temple! ...
But this live scape-goat let go in the wilderness, over which, in the exhaustive language of Leviticus 16:21, the high-priest had confessed and on which he had laid all the iniquities of the children of Israel, and all their transgressions in all their sins, meant something quite different. It meant the inherent weakness and unprofitableness of the commandment; it meant, that the law made nothing perfect, but was the bringing in of a better hope; that in the covenant mercy of God guilt and sin were indeed removed from the people, that they were covered up, and in that sense atoned for, or rather that they were both covered up and removed, but that they were not really taken away and destroyed till Christ came; that they were only taken into a land not inhabited, till He should blot it out by His own blood; that the provision which the Old Testament made was only preparatory and temporary, until the time of the reformation; and that hence real and true forgiveness of sins, and with it the spirit of adoption, could only be finally obtained after the death and resurrection of the Lamb of God which taketh away the sin of the world. ...
The word Azazel, which only occurs in Leviticus 16, is by universal consent derived from a root which means wholly to put aside, or, wholly to go away. Whether, therefore, we render la-Azazel by for him who is wholly put aside, that is, the sin-bearing Christ, or for being wholly separated, or put wholly aside or away, the truth is still the same, as pointing through the temporary and provisional removal of sin by the goat let go in the land not inhabited, to the final, real, and complete removal of sin by the Lord Jesus Christ, as we read it in Isaiah 53:6: Jehovah hath made the iniquities of us all to meet on Him. ...
Yet annually anew, and each time confessedly only provisionally, not really and finally, till the gracious promise (Jer 31:34) should be fulfilled: I will forgive their iniquity, and I will remember their sin no more. Accordingly it is very marked, how in the prophetic, or it may be symbolical, description of Ezekiels Temple (Eze 40-46) all mention of the Day of Atonement is omitted; for Christ has come an high-priest of good things to come, and entered in once into the Holy Place, to put away sin by the sacrifice of Himself (Heb 9:11, 12, 26).

A parable . . .
Once upon an era in a land & time far away . . .
A tribal chieftan married the beautiful elder daughter of a neighboring chieftan.
They lived happily for a couple of decades when there was a war and the wife was captured and taken away captive.
The hubby was racked with grief for months. A visiting magistrate came through on a tour about that time and asserted very emphatically that the first wife had been killed in a fit of rage by her drunken captors.
After a couple of years, the beloved hubby packed his grief away and married the elder daughter of another neighboring chieftan on the opposite side of his tribal lands. They lived happily for 5 years.
Then a slave trader came through. Hubby authorized wife #2 to purchase a new household slave. After getting the new woman home and cleaned up, what a surprise, it was wife #1!
Hubby was beside himself with joy. Wife #2 was shocked and a bit taken aback but loved the hubby so much she decided she'd love what he loved including wife #1.
Both covenants were affirmed and the tribe was enriched happily ever after.
I have to agree, just as Tabernacles ties up with the first coming.
