acts 23:8 For the Sadducees say that there is no resurrection, neither angel, nor spirit: but the Pharisees confess both. - Free Bible Online

      8. the Sadducees say . . . there is no resurrection, neither angel, nor spirit--(See on Lu 20:37).
      the scribes . . . of the Pharisees' part . . . strove, saying, We find no evil in this man, but--as to those startling things which he brings to our ears.
      if a spirit or an angel hath spoken to him--referring, perhaps, to his trance in the temple, of which he had told them (Ac 22:17). They put this favorable construction upon his proceedings for no other reason than that they had found him one of their own party. They care not to inquire into the truth of what he alleged, over and above their opinions, but only to explain it away as something not worth raising a noise about. (The following words, "Let us not fight against God," seem not to belong to the original text, and perhaps are from Ac 5:39. In this case, either the meaning is, "If he has had some divine communication, what of that?" or, the conclusion of the sentence may have been drowned in the hubbub, which Ac 23:10 shows to have been intense).
