Bible Dictionary: Urim & ThummimBy: Guy Templeton
The LDS Bible Dictionary says for Urim & Thummim
“Hebrew term that means ‘Lights and Perfections.’….Using a Urim and Thummim is the special prerogative of a seer, and it would seem reasonable that such instruments were used from the time of Adam. However, the earliest mention is in connection with the brother of Jared (Ether 3:21-28). Abraham used a Urim and Thummim (Abr. 3:1-4), as did Aaron and the priests of Israel, and also the prophets among the Nephites (Omni 1:20-21; Mosiah 8:13-19; 21:-26-28; 28:11-20; Ether 4:1-7). There is more than one Urim and Thummim, but we are informed that Joseph Smith had the one used by the brother of Jared (Ether 3:22-28; D&C 10:1; 17:1)”
If we sustain the Twelve and “prophets, seers, and revelators”, why do you think the Urim and Thummim hasn’t been used since the days of Joseph Smith? Would it be more accurate to simply call them “prophets and revelators” and not seers?
