Jubilee Explained by a Messianic Jew

jdLet's talk about Jubilee for a moment...
In Judaism, the festivals (moedim-appointed times) foreshadows things to come -much how Yeshua fulfilled Passover. (Colossians 3:16-17). We first see the festival of Jubilee in Leviticus 25. In Leviticus 25:9 we see the mention of a "loud" (or lit. "great) "trumpet" that declares the forgiveness of debts for the Covenant people of god and liberty throughout the land of Israel. In 25:3 the Covenant Keepers return to their homes in Israel from afar. Rabbis foresee this as the resurrection of Israel in the age of diaspora. The prophets speak of this theme, too, along with the "great trumpet". E.g., Isaiah 27:12-13 and Ezekiel 37:1-13).
Yeshua connects his return with the sounding of the loud (or lit. "great" trumpet in Matthew 24:29-31. This is the year of Jubilee. Paul picks up on this theme first in his discourse about the resurrection when speaking in 1 Corinthians 15:51-53. Paul, as did all of Israel then, spoke of the Jubilee using the circumlocations "load, great, last, and the Trumpet".
In circa 49-51 A.D., false teachers were going around and claiming that this resurrection | Jubilee already happened with the rising of Yeshua into heaven. (cf. Matthew 27:51-53 with 2 Timothy 2:16-18. Paul puts there worries to rest in Thessalonians 4:13-18. Note in verse 16, Paul connects the resurrection with "the Trumpet". This Trumpet is the Jubilee when all of our debts are forgiven Matthew 6:12.
Many in Christianity are taught that we all will go into heaven, according to 1 Thess. 4:17. This is not the case. The kingdom of God and the Messianic Age will be on earth. (Matthew 6:10; Revelation 21:2). When Paul said in 1 Thessalonians 4:17 that the Saints will be caught up in the clouds, he is again drawing on the words of Isaiah 60:8: "Who are these that fly like a cloud and like doves to their windows?" Isaiah is speaking of the regathering of God's people.
Yeshua explains our destination in his parable about the weeds in Matthew 13:36-43, rebuilding a righteous Israel.
In conclusion, the great Jubilee is a "Sabbath". In Hebrew the word means "rest" (shabbat). This is why Yeshua is known as our "rest" and the author of Hebrews says, "...there remains a Sabbath Rest (Jubilee) for the people of God." (Hebrews 4:8-10). Meaning, the great Jubilee has yet to occur- putting to rest the fears of those who think the resurrection already happened.
Of course, this is a very superficial explanation. The whole study is very beautiful and inspiring. I pray it helps you understand my belief on the topic.
I am pleased to hear you are not a believer in the pagan-based trinitarian doctrine. You are correct. Sadly so many otherwise faithful and sincere believers have no knowledge about the source of some of the doctrines they believe in - like the Trinity. They merely trust in what they're told by ministers without really investigating God's Word to confirm their truthfulness. This ids how the devil divides us. He tried the same thing with Yeshua in the wilderness when he tested Him. That whole encounter was about the true understanding of God's Word. Some liken the encounter to theological differences between the materialist and corrupt Sadducees and the Pharisees. Contrary to what traditional Christianity teaches, Yeshua did not say the Pharisees where wrong. He did rebuke a handful of Pharisees who were corrupt. Those that were not corrupt, Yeshua ordered us to obey. Matthew 23:1-3. Paul never denounce being a Pharisee, either. Acts 23:6: Philippians 3:6.
