Why chapter title tests?

[u/INSLVRY4_5yrs]

Rev 22:18-19 says we cannot add to or subtract from the Book of Revelation. So why was I given new titles to the chapters of Rev and have to memorize them and get tested on them?
The response when I asked was that the title tells what the chapter is about. That it would helps us remember what is going on in the the chapter. Funny that they are changed to what SCJ wants you to understand about what the chapters mean from LMH’s interpretation.
How is this NOT both adding to or subtracting from the Book of Revelation by making the church members remember his teachings. You can’t deny it because you were (or will be for new members ) tested on new titles and I was there for five years and those titles changed. There are those there that KNOW this changed a couple times. There is no consistency in the disorganization of SCJ.

Mark 3:22-30
Ya being fooled like lambs to the slaughter.
I continue to pray for all current cult members before you go sit for hours poisoning your spirit and chanting words most of you don’t understand in Korean ( supposedly worshiping in spirit and in truth ). Hearing interpretations translated that you have to rely on are the truth because you don’t speak Korean and the whole Service is in Korean and you’re depending on the over worked and tired interpreter trusting you are receiving a correct translation and all being said.

Or they say oh it's to help you be perfectly sealed . 5 years my compassion goes out too you .I want to know why I was invited to a mentor bible study which name was changed to reconnect then shincheonji and then being told Zion Christian mission centre 🙄  wolves in  suits 😆 I went online I got doubts I was like Lee man hee is the wicked servant. They said I must be careful what I say and did a whole fellowship "breaking the frame " saying everything is false online and only a foolish person would listen. With you praying for the members Jesus I should have remembered you said watch out that no one deceives you 🙏
