In LDS theology, the keys of the priesthood, and the authority thereof, are held by, and active in, the Prophet. The Twelve hold these same keys and authority, but in a dormant state while the Prophet lives.
Actually, there are 15, including prophet…something NOT Biblical…and very strange since LDS Church claims to be like the original church
We also believe that the Twelve (15) are special witnesses of Christ whose charge mainly includes the responsibility to maintain the proper belief in, and practice of, Christ’s Gospel. The books between the Gospels and Revelation constitutes example of the apostles doing such. The Church struggled with straying in the presence of the Apostles and Prophet. I do not know how quickly the Church fell away following the death of the Apostles, but I do not believe that the Church can survive for long without them.
Luckily, they did not have to. Just as the LDS Church passes on alleged authority, so did the Original 12. They were not stupid. They knew they needed to. They passed on authority that has been passed for over 2000 years
We believe that anyone can be a prophet. We believe, however, that each person can only receive revelation, from God, for those whom we have authority over. Thus, I can receive revelation for my family and for those that fall under my position within the Church. With regards to those who fall under my position within the Church, I cannot receive revelation beyond the scope of said position. If I were a Sunday School teacher, the revelation I would receive would only be in regards to teaching the material, not in regards to adding to the material. Also, as a Sunday School teacher I would not receive revelation outside of teaching with regards to those in my class. A Bishop can receive revelation for his ward, but such revelation again is limited in scope as well. A Bishop cannot receive revelation that adds to, alters or conflicts with doctrines of the Church, such is beyond the scope of his position. Care should be taken with regard to personal revelation, the following is an excerpt from a talk on the subject:
That sounds very nice. And it might actually work if we did not have record of all the strange and invalid revelations from your past prophets.
I hope this answers your question.
thank you for your comments. and welcome
