The Biblical definition of treason is siding with the Jews.
Judas Iscariot is a founding member of that Fraternity of Treason.
This fraternity is populated by men who were called and chosen to preach the Gospel of Jesus Christ. They pray for the sick, cast out demons, preach the Gospel — all things that Judas Iscariot did. Even at the end, Judas called Jesus “Rabbi” and publicly displayed affection (a kiss) toward Him. That’s what treason looks like.
The church today is full of traitors, ashamed of the words of Jesus Christ (John 8:44) and siding with the Jews, all while pretending to play a part — just like Judas Iscariot.
This is the harlot — come out of her. (Rev 18:4)
