Those who were given the Book didn’t differentiate except after the Evidence came to them.
In all periods, those who were given the Book were differentiated into different schisms after receiving new Messengers and Books from the Lord through those Messengers. Today, the only Book that Allah satisfied for all mankind is Adhikr. The Arabic Qur’an Reading Fujjar who made their food rejecting Adhikr do not utilize It and do not give It to others for utilization. Thus, they are differentiated into different organizations and are included in Satan’s party mentioned in verse 58:19 without being included in Allah’s Single party mentioned in verse 58:22. They do not approve the Lord who taught Adhikr from the Paradise itself as Impartial and do not utilize Adhikr as the Balance. Against them, the verses they have seen, heard, touched, and read will witness and argue, and will push them to Hell as explained in verse 9:82. See explanation 23:51-53; 42:13-14 and 45:17.
