Better English by Grok:
The concept of purgatory appears to be derived from the Apocrypha, but it is not canonically legitimate. Humans lack a true understanding of what canonization entails in conveying historical truth, as we inherently lack the ability to record history accurately. Among the thousands of civilizations that have ever existed on the surface of the Earth, only the Chinese and the Jews possess relatively complete historical records.
(Possibly, God preserved Chinese history as a reference—the only one available. However, humans lack the insight to examine it in detail, as the god of this world has blinded their minds.)
Chinese history is canonized; without canonization, there would be no Chinese history. This illustrates how critical canonization is for preserving historical information. Canonization involves ongoing efforts by an authority to preserve content and pass it down through generations. Successive Chinese governments have been responsible for maintaining and transmitting this canon of history.
By the same token, the canonization of both the New Testament (NT) and Old Testament (OT) requires sustained effort from a dedicated authority. OT canonization began with King Hezekiah; it is said that 17 out of the 24 books bear his seal. Kings can serve as authorities in conveying secular history, much like in the Chinese tradition. However, kings (which are Caesars) cannot be reliable authorities working for God. God must select His own earthly authorities during different periods (similar to the role of successive Chinese governments in preserving secular history). By the time of Jesus, the Pharisees were sitting in Moses' seat and acted as such an authority. The last two books added to the OT Canon are believed to be those written in Aramaic rather than Hebrew, completing the 24-book OT Canon guarded by the Pharisees (the Sadducees did not have a full canon, as they embraced only the first five books which is the Law). (The corresponding authority for the NT is God's earthly Church.)
The Chinese claim to have 5,000 years of history. The first 2,500 years of their canonical history (as recorded in the Shiji) were written by a single person who never left his house. One can imagine how a solitary individual, confined to his house without traveling, could reliably document 2,500 years of history. Yet this represents the pinnacle of human capability in writing history! It is Satan's effort to deceive humans into overestimating their abilities and to lure them toward an unattainable ideal (symbolized by the Tree of Knowledge). As a result, humans judge the Bible as "imperfect" or "erroneous" based on this impossible standard, while overlooking actual human limitations.
That said, purgatory is not a canonical concept and is therefore not legitimate (if one understands what canonization truly means). The Septuagint (LXX) was an effort to translate Jewish writings into Greek for the Hellenistic world, benefiting even Jews who spoke only Greek (possibly including Saint Stephen, the first martyr). Its accuracy was maintained by various publishers rather than a central authority (such as the Pharisaic elites in the Jewish Great Sanhedrin). In contrast, the Hebrew versions of the canonical OT Scriptures were "published" or copied by scribes authenticated by the Pharisees and the Great Sanhedrin. These were controlled copies, whereas the LXX consisted of uncontrolled copies.
When the NT was canonized, Christians conveniently adopted the LXX as their OT Canon because it was written in Greek (the same language as the NT). However, the true nature of canonization is that the OT belongs to the Jews—it is their testimony, canonized from the time of King Hezekiah through Ezra and the Pharisees. The NT, on the other hand, belongs to Christians—it is the testimony of Jewish Christians and their canonization process. The Apocrypha's legitimacy is thus excluded. The LXX can serve only as a reference to the original Jewish OT Canon.
The Judgment of the Covenant (as opposed to the Law) is a subjective judgment from a just and fair God (who is Christ). Jesus will consider all factors—including one's heart and mind—to deliver a fair judgment under any circumstances and determine who enters Heaven. Purgatory is never necessary in this context.
