I have not followed the G&S situation closely from the beginning. I've only done my "duty" to read and to vote my conscience, but it seems to me that most of what are put up as "guides and standards" are just that--handbooks of instruction--when the Lord, to my mind, didn't ask for such and already said that His scriptures are sufficient for that purpose.
(A&C)."When you have an agreed statement of principles I require it to also be added as a guide and
standard for my people to follow"
"I have given to you my doctrine, and have also revealed teachings, commandments, precepts, and principles to guide you and it is not meet that I command you in all things—reason together and apply what I have given you and it will be enough."
"Study my words and let them be the The Covenant standard for your faith"
"Receive the scriptures approved by the Lord as a standard to govern you in your daily walk in life"
"Use the scriptures to correct yourselves and to guide your words, thoughts and deeds"
In other words, use the scriptures for your handbook of instructions.
What He has asked for, again to my mind, is not the regurgitated answers that can be memorized or found in the book or copied from your neighbor. This is an open-book test (if you will). Therefore, what He has asked for is "an agreed statement of principles"--the reasons the answers are what they are. He is asking if we understand who God is and wants to know upon which ideologies we stand. Do we uphold the principle of charity or love (for "God is love" John 2:2)? If so, we have the golden rule to define love. Do we uphold the principle of choice or freedom to worship as we will--without coercion or compulsion? Do we uphold the principle of truth (of seeking to find it and never knowingly misrepresenting the reality)? Do we uphold the principle of mercy (of self-sacrifice and interceding on behalf of others)? Do we uphold the principle of hope--having even "a perfect brightness" (2 Nephi 13:5)?
Faith, repentance, obedience. Worshipping not ourselves.
The Lectures on Faith and the actions and words of our Christ both allow us to understand who God is, but that alone is not sufficient. We also have to show that we are willing to become as God is, "not only to say, but to do that which [Christ] has written" (D&C something or other).
Anyway, I do not have a formal "statement of principles" written, although I think one could be written and easily agreed upon, "a light thing" indeed, even by 100% of Christ's people if in deed any of us can ever be called such.
