sadducees
   the origin of this jewish sect cannot definitely be traced. it
   was probably the outcome of the influence of grecian customs and
   philosophy during the period of greek domination. the first time
   they are met with is in connection with john the baptist's
   ministry. they came out to him when on the banks of the jordan,
   and he said to them, "o generation of vipers, who hath warned
   you to flee from the wrath to come?" matt. 3:7. the next time
   they are spoken of they are represented as coming to our lord
   tempting him. he calls them "hypocrites" and "a wicked and
   adulterous generation" matt. 16:1-4; 22:23. the only reference
   to them in the gospels of mark 12:18-27 and luke 20:27-38 is
   their attempting to ridicule the doctrine of the resurrection,
   which they denied, as they also denied the existence of angels.
   they are never mentioned in john's gospel.
   
     there were many sadducees among the "elders" of the sanhedrin.
   they seem, indeed, to have been as numerous as the pharisees
   acts 23:6. they showed their hatred of jesus in taking part in
   his condemnation matt. 16:21; 26:1-3, 59; mark 8:31; 15:1; luke
   9:22; 22:66. they endeavoured to prohibit the apostles from
   preaching the resurrection of christ acts 2:24, 31, 32; 4:1, 2;
   5:17, 24-28. they were the deists or sceptics of that age. they
   do not appear as a separate sect after the destruction of
   jerusalem.
