50 And again we bear record -- for we saw and heard, and this is the testimony of the gospel of Christ concerning them who shall come forth in the resurrection of the just --
51 They are they who received the testimony of Jesus,...
71 And again, we saw the terrestrial world, and behold and lo, these are they who are of the terrestrial, whose glory differs from that of the church of the Firstborn who have received the fulness of the Father, even as that of the moon differs from the sun in the firmament.
72 Behold, these are they who died without law;
73 And also they who are the spirits of men kept in prison, whom the Son visited, and preached the gospel unto them, that they might be judged according to men in the flesh;
74 who received not the testimony of Jesus in the flesh, but afterwards received it.
81 And again, we saw the glory of the telestial, which glory is that of the lesser, even as the glory of the stars differs from that of the glory of the moon in the firmament.
82 These are they who received not the gospel of Christ, neither the testimony of Jesus.
If you accept Joseph Smith's definition of "the testimony of Jesus" (from my previous post) can you see why it is important that current apostles and prophets get it right? Do they have the authority to change the definition of "the testimony of Jesus"? Did those who changed the doctrine have the testimony of Jesus, i.e. the spirit of prophecy, i.e. calling and election made sure when they made the change, or just dropped the topic altogether from current doctrine? If so, if they had their calling and election made sure why would they neglect teaching it to others?11 As I pondered over these things which are written, the eyes of my understanding were opened, and the Spirit of the Lord rested upon me, and I saw the hosts of the dead, both small and great.
12 And there were gathered together in one place an innumerable company of the spirits of the just, who had been faithful in the testimony of Jesus while they lived in mortality;
13 And who had offered sacrifice in the similitude of the great sacrifice of the Son of God, and had suffered tribulation in their Redeemer's name.
14 All these had departed the mortal life, firm in the hope of a glorious resurrection, through the grace of God the Father and his Only Begotten Son, Jesus Christ.
