I came across this in one of the sites, now does this encompass all the Pillars of Adventism, what are your thoughts...

"... The five main pillars of Adventism are these:
1.) Jesus Christ our Lord and Saviour from sin [Gospel Revelation 14:6-12]
2.) Jesus Christ as Great High Priest in His most holy Sanctuary Temple in heaven.
3.) Jesus Christ and His own holy day of worship
4.) Jesus Christ and His advent to come and reign in power and glory to end sin.
5.) Jesus Christ and eschatology, the apocalyptic prophecies about the endtime.

Here is SOP on the subject, does anyone have any other quotes...

The Sabbath~
There are the main pillars of our faith, subjects which are of vital interest, the Sabbath, the keeping of the commandments of God. ...{CW 77.1}

The Sanctuary~
As the great pillars of our faith have been presented, the Holy Spirit has borne witness to them, and especially is this so regarding the truths of the sanctuary question. Over and over again the Holy Spirit has in a marked manner endorsed the preaching of this doctrine. But today, as in the past, some will be led to form new theories and to deny the truths upon which the Spirit of God has placed His approval.--Manuscript 125, 1907. {Ev 224.2}

The Three Angels Messages - Revelation 14~
What influence is it would lead men at this stage of our history to work in an underhand, powerful way to tear down the foundation of our faith--the foundation that was laid at the beginning of our work by prayerful study of the Word and by revelation? Upon this foundation we have been building for the past fifty years. Do you wonder that when I see the beginning of a work that would remove some of the pillars of our faith, I have something to say? I must obey the command, "Meet it!" . . . {1SM 207.3}
I must bear the messages of warning that God gives me to bear, and then leave with the Lord the results. I must now present the matter in all its bearings; for the people of God must not be despoiled. {1SM 208.1}
We are God's commandment-keeping people. For the past fifty years every phase of heresy has been brought to bear upon us, to becloud our minds regarding the teaching of the Word--especially concerning the ministration of Christ in the heavenly sanctuary, and the message of Heaven for these last days, as given by the angels of the fourteenth chapter of Revelation. Messages of every order and kind have been urged upon Seventh-day Adventists, to take the place of the truth which, point by point, has been sought out by prayerful study, and testified to by the miracle-working power of the Lord. But the waymarks which have made us what we are, are to be preserved, and they will be preserved, as God has signified through His Word and the testimony of His Spirit. He calls upon us to hold firmly, with the grip of faith, to the fundamental principles that are based upon unquestionable authority. {1SM 208.2}

The Personality of God or Christ~
Those who seek to remove the old landmarks are not holding fast; they are not remembering how they have received and heard. Those who try to bring in theories that would remove the pillars of our faith concerning the sanctuary or concerning the personality of God or of Christ, are working as blind men. They are seeking to bring in uncertainties and to set the people of God adrift without an anchor. {MR760 9.5}

The pillars of the Christian faith:

"Infidelity prevails to an alarming extent, not in the world only, but in the church. Many have come to deny doctrines which are the very pillars of the Christian faith. The great facts of creation as presented by the inspired writers, the fall of man, the atonement, the perpetuity of the law--these all are practically rejected by a large share of the professedly Christian world. Thousands who pride themselves on their knowledge regard it as an evidence of weakness to place implicit confidence in the Bible, and a proof of learning to cavil at the Scriptures and to spiritualize and explain away their most important truths." {PK 625.2}

I believe "pillars" and "landmarks" are synonymous.

"Then there will be a removing of the landmarks, and an attempt to tear down the pillars of our faith." {RH, December 13, 1892 par. 2}

"Spurious scientific theories are coming in as a thief in the night, stealing away the landmarks and undermining the pillars of our faith." {RH, April 14, 1903 par. 27}

If this is so, the most encompassing list would be the following one:

"The passing of the time in 1844 was a period of great events, opening to our astonished eyes the cleansing of the sanctuary transpiring in heaven, and having decided relation to God's people upon the earth, [also] the first and second angels' messages and the third, unfurling the banner on which was inscribed, "The commandments of God and the faith of Jesus." One of the landmarks under this message was the temple of God, seen by His truth-loving people in heaven, and the ark containing the law of God. The light of the Sabbath of the fourth commandment flashed its strong rays in the pathway of the transgressors of God's law. The nonimmortality of the wicked is an old landmark. I can call to mind nothing more that can come under the head of the old landmarks. All this cry about changing the old landmarks is all imaginary." {CW 30.2}

There was a short thread on this a few years back. Here it is: Pillars/Landmarks

My list from the thread looks different, but I think they are fundamentally equivalent.

Well when I went to do a study, I was amazed that I could not find hardly any material on any of the churches sites, no outlines of the foundations, no historical background on how we received the specific 'pillars'. So I thought well, let me just ask, and you would be surprised at some of the replies and answers I came across.....

Well lets compare from the previous thread I see you have:
"..I see here a very short list of landmarks:
1.cleansing of the sanctuary

2.three angels' messages

3.commandments of God

4.faith of Jesus

5.temple of God in heaven

6.Sabbath

7.nonimmortality of the wicked...."

Everyone seems to agree there are seven, but which seven, here is one of the more complete lists which we can compare:

RBF (I would say this is Righteousness by Faith)
SOP (This is easy, Spirit of Prophecy)
victory over sin (Justification/Sanctification?)
State of the Dead (I see this one a lot and 'nonimmortality')
health message (I think this is a unique pillar)
Law 10C (Sabbath) (Is this 2 or correct combined?)
Sanctuary (This is the only one I consistently see on all the lists.....)

I believe the expanded view of the pillars is the 28 fundamental beliefs. Not one of the 28 can be eliminated without compromising the message.

Yes, but Adventism brought certain truths to the forefront which the Reformation had not being able to, or was not revealed to it. These are the Pillars of Adventism while the 28 fundamental beliefs is more of a institutional declaration.

Richard, perhaps I'm missing the point because I see no difference between the pillars of Adventism and the 28 fundamental beliefs of Adventism. What I am missing here? Please help me understand your point. Thank you.

I think he means, besides the beliefs we have in common with other churches, there is a set of truths which led to the formation of the SDA Church as a distinct church - these specific truths would be the "pillars."
According to our pioneers, Adventism began with the proclamation of the first angel's message, in 1840. The second angel, with the proclamation of the fall of Babylon, brought them "to the 7th month, 1844." After this the third angel's message began to be proclaimed. On the basis of the three angels' messages, SDAs would see themselves as people with a prophetic origin. (See Knight, Joseph Bates: Real Founder os SDAism, p. 143-146.
The three angels' messages also put in a chronological sequence some of the main doctrinary components of SDAism. The preaching "the hour of His judgment is come" (Rev. 14:7) led the way to the establishment of the investigative judgment. A corolary of this judgment was the conditional immortality, for if the dead received their reward at death there would be no need for an investigative judgment. The proclamation of the "commandments of God" (Rev. 14:12) by the third angel was understood as emphasizing the perpetuity of the law and the Sabbath. Also, the connection between the law/sabbath and the sanctuary is seen in Rev. 11:19.
The pillars could also include the second coming of Christ, for which the third angel's message prepares the way, and the prophetic gift.

This is analyzed in detail in Alberto Timm's Ph.D. Thesis, "The Sanctuary and the Three Angels' Messages, 1844-1863: Integrating Factors in the Development of Seventh-day Adventist Doctrines" (AU, 1995).
