What is the X in X-mas?
Old English, from Late Latin Sadducaei (plural), from Greek Zaddoukaios, an inexact transliteration of Hebrew tzedoqi, from personal name Tzadhoq "Zadok" (2 Sam. viii:17), the high priest from whom the priesthood of the captivity claimed descent. According to Josephus, the sect denied the resurrection of the dead and the existence of angels and spirits; but later historians regard them as more the political party of the priestly class than a sect per se. Related: Sadducean.
