The further implication being that the Urim and Thummim could be used today as they were in Bible times which is false. The Urim and Thummim were part of a now-defunct sacricial system.
The Urim-Thummim-spectacle thing is one of Joe Smith's quirkier contentions though he did have his large share of them.
Actually my understanding of Apostles is that they are not one in subtanse as the Greek's like to pontificate but one in the way Jesus explains he and his Father are one as he prays for the Apostles. He saying one "Essense" (Greek philosophy).
John 17:19 And for their sakes I sanctify myself, that they also might be sanctified through the truth. 20 Neither pray I for these alone, but for them also which shall believe on me through their word; 21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. 22 And the glory which thou gavest me I have given them; that they may be one, even as we are one: 23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
Acts 7:55 But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God, 56 And said, Behold, I see the heavens opened, and the Son of man standing on the right hand of God.
