I'm not big on the term "present truth". Still don't know why it's used or what it's suppose to mean. I consider all truth to be "present truth".
As far as the rest of your statement, Paul was not the singular authority in regards to the gospel message. The gospel does indeed contain all that you mentioned above. The sabbath is included in the law, which you believe has been done away with. The IJ is a term given to explain what Christ is currently doing in the MHP. The three angels message is God's last proclimation to a sinful world to get it together.
So in other words we have the law of God - repentance, and judgment, which are all apart of the gospel.
Present truth and the Pillars
The early Adventists emphasized the concept of "present truth" -- see
2 Peter 1:12 (
NKJV). James White explained, The church [has] ever had a present truth. The present truth now, is that which shows present duty, and the right position for us
Present truth is
present truth, and not future truth, and the Word as a lamp shines brightly where we
stand, and not so plainly on the path in the distance. Ellen White pointed out that present truth, which is a test to the people of this generation, was not a test to the people of generations far back.
[8] The founders of the SDA church had a dynamic concept of what they called
present truth, opposed to creedal rigidity, and had an openness to new theological understandings that built upon the
landmark doctrines, or Pillars of Adventism that had made them a people.
[9]
These foundations, pillars, and landmarks are:
- the investigative judgment,
- the sanctuary that brings this judgment to light,
- the three angels messages of Revelation,
- the law of God,
- the faith of Jesus,
- the Sabbath,
- the state of the dead, and
- the special gift of prophecy.[10]
Still, the possibilities of dynamic change in Seventh-day Adventist beliefs are not unlimited.
[11] Those
landmark doctrines are non-negotiables in Adventist theology. Collectively they have provided the Seventh-day Adventists with an identity.
[12] The
pillars of their faiththe Bible doctrines that define who they are as a peoplehave been thoroughly studied out in the Scripture and have been attested to by the convicting power of the Holy Spirit. As Ellen White put it, "When the power of God testifies as to what is truth, that truth is to stand forever as the truth. ... Men will arise with interpretations of Scripture which are to them truth, but which are not truth. The truth for this time, God has given us as a foundation for our faith.
[13] Robert Johnston noted, Without repudiating the past leading of the Lord, it [the Seventh-day Adventist church] seeks even to understand better what that leading was. It is always open to better insights to learnto seek for truth as for hid treasure.
Adventists are still pilgrims on a doctrinal journey who do not repudiate the
way marks, but neither do they remain stopped at any of them.
[14] Ellen further said that there is more truth to be revealed and that true doctrine will stand close investigation.
[15] But there is a solid foundation to build new truth upon.
