The Marks Of Tribulation

I have been hiding this for too long. I need your help to decrypt this weird made-up language for me. They appeared on my now defunct FlaminTales Discord and I saved them in my pictures folder. The users were just sending in cryptic pictures as if they did not want anybody else to get involved.
== This was the first message ==
This just seems to be one letter, but it could mean something larger.
Some strange things have been happening in Minecraft: Bedrock Edition as well. Maybe it is somehow related as the strange occurrences happened after I downloaded the text. I may upload them soon.
==This was the second one==
These could be logos that resemble letters. 
Maybe they contain phrases as well that can be decoded to English, but I need more info about it to be sure.
== This was the last one ==
This one was sent a few seconds before I shut down the Discord for inactivity purposes and the intruders all wrote in in unison.
== Minecraft symbols ==
This symbol can be seen in my recent minecraft video it is as if somoen was able to send them in live as i was editing which just makes it even more bizarre...
I am certain that they use those to simplify long phrases or words
