Question: Where is the Apostle John and the three witnesses today? If they are still on earth, than apostasy is impossible because a living apostle is present on earth. If they are not alive today and on earth, then the follow passage from the Book of Mormon is in error.

THE SON OF NEPHI, WHO WAS THE SON OF HELAMAN
CHAPTER 28
5 And they sorrowed in their hearts, for they durst not speak unto him the thing which they desired.
6 And he said unto them: Behold, I aknow• your thoughts, and ye have desired the thing which bJohn•, my beloved, who was with me in my ministry, before that I was lifted up by the Jews, desired of me.
7 Therefore, more blessed are ye, for ye shall anever• taste of bdeath•; but ye shall live to behold all the doings of the Father unto the children of men, even until all things shall be fulfilled according to the will of the Father, when I shall come in my glory with the cpowers• of heaven.
8 And ye shall never endure the pains of death; but when I shall come in my glory ye shall be changed in the twinkling of an eye from amortality• to bimmortality; and then shall ye be blessed in the kingdom of my Father.
9 And again, ye shall not have pain while ye shall dwell in the flesh, neither sorrow save it be for the asins• of the world; and all this will I do because of the thing which ye have desired of me, for ye have desired that ye might bbring• the souls of men unto me, while the world shall stand.
10 And for this cause ye shall have afulness• of joy; and ye shall sit down in the kingdom of my Father; yea, your joy shall be full, even as the Father hath given me fulness of joy; and ye shall be even as I am, and I am even as the Father; and the Father and I are bone•;
11 And the aHoly• Ghost beareth record of the Father and me; and the Father giveth the Holy Ghost unto the children of men, because of me.
12 And it came to pass that when Jesus had spoken these words, he touched every one of them with his finger save it were the athree• who were to tarry, and then he departed.
13 And behold, the heavens were opened, and they were acaught• up into heaven, and saw and heard unspeakable things.
…
15 And whether they were in the body or out of the body, they could not tell; for it did seem unto them like a atransfiguration• of them, that they were changed from this body of flesh into an immortal state, that they could behold the things of God.
16 But it came to pass that they did again minister upon the face of the earth; nevertheless they did not minister of the things which they had heard and seen, because of the commandment which was given them in heaven.
17 And now, whether they were mortal or immortal, from the day of their transfiguration, I know not;
…
21 And thrice they were cast into a afurnace• and received no harm.
22 And twice were they cast into a aden• of wild beasts; and behold they did play with the beasts as a child with a suckling lamb, and received no harm.
23 And it came to pass that thus they did go forth among all the people of Nephi, and did preach the agospel of Christ unto all people upon the face of the land; and they were converted unto the Lord, and were united unto the church of Christ, and thus the people of bthat• generation were blessed, according to the word of Jesus.
…
25 Behold, I was about to write the anames• of those who were never to taste of death, but the Lord forbade; therefore I write them not, for they are hid from the world.
26 But behold, aI• have seen them, and they have ministered unto me.
27 And behold they will be aamong• the Gentiles, and the Gentiles shall know them not.
28 They will also be among the Jews, and the Jews shall know them not.
29 And it shall come to pass, when the Lord seeth fit in his wisdom that they shall minister unto all the ascattered tribes of Israel, and unto all nations, kindreds, tongues and people, and shall bring out of them unto Jesus many souls, that their desire may be fulfilled, and also because of the convincing power of God which is in them.
…
40 And in this state they were to remain until the judgment day of Christ; and at that day they were to receive a greater change, and to be received into the kingdom of the Father to go no more out, but to dwell with God eternally in the heavens.
