From what I've heard, many people are disfellowshipped from the LDS for not agreeing on even trivial points of doctrine.
There are two ways of dealing with apostacy, doctrinal disagreements, and other "big" sins in the LDS Faith.
1 - Disfellowship(ment) is the first. It means to silence someone from teaching, leading prayer, and acting in a "priesthood" calling. It is a lesser sanction. One who has been disfellowshipped is encouraged to participate in learning anew the doctrine of the church. Those persons may not teach in any way, nor even participate in discussions, except to ask questions. They may not answer other classmates' questions as if to declare, define, or guide the class.
2 - Ex-communication is the heaver sanction. Here, the individual so sanctioned is literally kicked out. They lose the previously experienced church blessings, endowments, and ordinances. These include Baptism, Confirmation, Priesthood Ordinations, Temple Endowments, and the like. It is possible for an individual to someday re-gain entrance into the LDS Church, but is a long, long process, which process is characterized by a period of repentance, and re-evaluation by the authority(s) decreeing the excommunication.
For an individual to admit to reading The Urantia Book is not, in and of itself, a sanctionable offense. To claim to espouse any teaching(s) within TUB that run counter to established LDS doctrine(s) may expose said indivitual to evaluation by a Bishop which may lead to a "in-house" sanction - Disfellowship(ment). It may, if deemed sufficiently aggregious, lead the Bishop to refer the individual up to the next-higher church authority, most usually to the High Council. The High Council may render a decision of either Disfellowshipment or Excommunication. Depending on the situation, excommunication may be publically announced, such as if the person was a Leader (like a Bishop, or Quorum President, or such), or an established Teacher, or whether the offense involved jeopardy to another person or class. Other times, excommunication may be kept more or less confidential.
To share any spiritual topic in such a manner as to even hint that any particular Church doctrine, ritual, or policy is untrue or wrong, is almost certain to expose that person to church sanctions. There have been at least 'several' individuals within the LDS church who have been excommunicated over their conflicts with the doctrine of the LDS church - including individuals who believe and share TUB. Disfellowshipment is not a sanction that is publically acknowledged, so I have no knowledge about any such involving Jesusonians who have accepted TUB.
There are many, very many within the LDS church who are extraordinally adverse to the merest mention of any 'Revelation' that did not come out from the mouth of 'The Prophet of the Church,' and some get vigorous in their objections and declarations of 'apostacy' on the part of the TUB believer. I have heard some folks declare that my very soul was in danger of eternal damnation, for even believing TUB was close to a 'good philosophy' or even 'uplifting' in its effect in my life. It's a sad situation - especially from a church which has its very foundation in 'latter-day' revelation!
As I said, most in the LDS church wholeheartedly espouse, and defend, continuing revelations from God to mankind - as long as it comes only from the President of the LDS Church, the Prophet. The prophet is Thomas S. Monson today, and he will hold that title and position until his death. The LDS church doctrine includes 'personal revelation' for each individual, as well as 'stewardship-revelation' for class leaders or Quorum Presidents or Bishops; but there is to be NO revelations for all mankind that do not originate with the President of The Church of Jesus Christ of Latter Day Saints - the LDS Prophet.
I am sad to admit that the LDS church went from a fresh, new revelatory religion into an evolutionary, ritual-heavy, doctrinally-obtuse religion almost as fast as it could! The evolutionary-izing of the LDS church has happened as an almost continuous process over the whole of its 182 year history.
