The majority text manuscript grouping known as Kx form the bulk of the manuscripts found within the majority text tradition. The grouping was first recognized and described in the West by textual scholar Hermann Von Soden in his (1901-1903), vols. Die Schriften des Neuen Testaments.
Von Soden recognized that these manuscripts with his designated Kx siglum where those manuscripts within the majority text stream that were neither Kr nor K1. The only distinction he made further in the newly designated grouping was according to the presence and type of profile of the PA or pericope adulterae i.e. (John 7:52-8:11) found within each manuscript. Typically, Kx manuscripts will have some form of the PA profile as found in the m5 or m6 groupings.
The problematic boundaries defining the Kx profile grouping complicate matters even more to a small degree in that the group’s textual profile is blurred to some extent in relatively unimportant variant sets. However, there is a basic identifiable overall profile, which can be distinguished from the other two main majority text profiles found in Kr/f35 and Ka/Pi. The links below provide a listing of the recognized Kx manuscripts within the group.
