false prophets and deceivers

 Read the canonical biblical books and do not leave them because there are 2000 years of confirmation for truth but that's in the Orthodox Church. The Protestant Church (which comes from the word "protest") has eliminated 10 books because they did not like what they said.

The Septuagint books are all canons because the Jews created the Septuagint in Greek. At that time, the Jews did not even understand Hebrew because Alexander the Great had conquered the world and the Jews all spoke Greek for so long that they did not know Hebrew. When Christianity came around, the Greeks used the Septuagint to prove that Jesus was the Messiah. The Dead Sea Scrolls proved that the Septuagint was more accurate than their Masoretic texts which were written 1200 years after the Septuagint. The pseudepigraphs were all in separate scrolls, so just because they were found in the same location, it does not mean that they are part of "official scripture."

The Christian Bible, the New Testament, has similar books like the Book of Judas ... which was written 200 years after the Resurrection. They are all called apocrypha but there are two types of apocrypha: the kind that are false and fiction that are not included in the Orthodox Bible. Then there are protestant apocrypha which were eliminated because Protestants did not like what they said and confirmed orthodoxy, even though they were canon for 1500 years. 2 Maccabees 12: 43-45 actually talks about praying for the Dead because the dead can not pray for themselves. By praying for the dead, you lift them up, which is why in the Orthodox Church we have memorials so we can pray to God to forgive the Sin of the reposed so that they may enter the kingdom of heaven
