A Revelation to Joseph & Oliver concerning John the Beloved Deciple who leaned on his Saveiours breast given in Harmony Susquehannah County Pennsylvania
A Revelation given to Joseph and Oliver, in Harmony, Pennsylvania, April, 1829, when they desired to know whether John, the beloved disciple, tarried on earth. Translated from parchment, written and hid up by himself.
6:1 And the Lord said unto me, John my beloved, what desirest thou? and I said Lord, give unto me power that I may bring souls unto thee.--And the Lord said unto me: Verily, verily I say unto thee, because thou desiredst this, thou shalt tarry till I come in my glory: 6:2 And for this cause, the Lord said unto Peter:--If I will that he tarry till I come, what is that to thee? for he desiredst of me that he might bring souls unto me: but thou desiredst that thou might speedily come unto me in my kingdom: I say unto thee, Peter, this was a good desire, but my beloved has undertaken a greater work. D&C 7:1-7
Revelation given to Joseph Smith the Prophet and Oliver Cowdery, at Harmony, Pennsylvania, April 1829, when they inquired through the Urim and Thummim as to whether John, the beloved disciple, tarried in the flesh or had died. The revelation is a translated version of the record made on parchment by John and hidden up by himself. HC 1:35-36 7:1 And the Lord said unto me: John, my beloved, what desirest thou? For if you shall ask what you will, it shall be granted unto you.7:2 And I said unto him: Lord, give unto me power over death, that I may live and bring souls unto thee. 7:3 And the Lord said unto me: Verily, verily, I say unto thee, because thou desirest this thou shalt tarry until I come in my glory, and shalt prophesy before nations, kindreds, tongues and people. 7:4 And for this cause the Lord said unto Peter: If I will that he tarry till I come, what is that to thee? For he desired of me that he might bring souls unto me, but thou desiredst that thou mightest speedily come unto me in my kingdom.7:5 I say unto thee, Peter, this was a good desire; but my beloved has desired that he might do more, or a greater work yet among men than what he has before done.7:6 Yea, he has undertaken a greater work; therefore I will make him as flaming fire and a ministering angel; he shall minister for those who shall be heirs of salvation who dwell on the earth. 7:7 And I will make thee to minister for him and for thy brother James; and unto you three I will give this power and the keys of this ministry until I come.
Note: Compare John 21:20-25
Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee? Peter seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee? This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true. And there are also many other things which Jesus did, the which, if they should be written every one, I suppose that even the world itself could not contain the books that should be written. Amen.
This is an interesting case in that this is a translation of a buried parchment where the text changes over time.
