Analysis of information sources in references of the Wikipedia article "Rabbi" in Vietnamese language version.
We suggest that the avoidance of the title "Rabbi" for pre-70 sages may have originated with the editors of the Mishnah. The editors attributed the title to some sages and not to others. The avoidance of the title for pre-70 sages may perhaps be seen as a deliberate program on the part of these editors who wanted to create the impression that the "rabbinic movement" began with R. Yochanan b. Zakkai and that the Yavnean "academy" was something new, a notion that is sometimes already implicitly or explicitly suggested by some of the traditions available to them. This notion is not diminished by the occasional claim to continuity with the past which was limited to individual teachers and institutions and served to legitimize rabbinic authority.
