The question is, are these things dutifully and faithfully taught? Or adulterated with man’s traditions and propagandas? Hadn’t both Jesus and Paul warned about end time apostasy, people falling away from faith?
So are you trying to say it is vain to try to learn what the Bible teaches because it all has been adulterated?
As far as it being that way because it is the end times:
2 Peter 2:1 But there
were also false prophets among the people, even as there will be false teachers among you . . .
I believe Peter is talking about all the false prophets in the Old Testament like Balaam.
Jeremiah 6:13 "Because from the least of them even to the greatest of them, Everyone is given to covetousness; And from the prophet even to the priest, Everyone deals falsely.
Ezekiel 13:9 "My hand will be against
the prophets who envision futility and who divine lies; they shall not be in the assembly of My people, nor be written in the record of the house of Israel, nor shall they enter into the land of Israel. Then you shall know that I am the Lord GOD.
Israel in Jesus' time was split up into Pharisee's, Sadducee's, and Essenes.
The Essenes are not directly mentioned in the Bible, but they were a Jewish sect during the Second Temple period, known for their strict observance of the Law and communal living. They are often associated with the Dead Sea Scrolls, which provide insights into their beliefs and practices.
There were also Zealot's at that time.
In the Bible, a zealot refers to a member of a Jewish political group known for their passionate opposition to Roman rule and their desire for Jewish independence. One of Jesus' disciples, Simon, is specifically identified as "Simon the Zealot."
I think it was the Zealots this verse is referring to:
John 6:15 Therefore when Jesus perceived that they were about to come and take Him by force to make Him king, He departed again to the mountain by Himself alone.
Anyhow, there have always been false teachers.
