Claim. A true person must align perfectly with the universe’s vertical and horizontal axes — accurate to within fractions of a millimeter against the cosmic standard — because subject-object partnerships move in perpendicular relationships and whatever loses perpendicularity is shattered.
Elaboration. The argument uses physics as analogy: Earth has orbited the sun for 4.5 billion years without deviating from formula by even one second, because catastrophic instability would result. Universal law requires that ‘subject and object partners always move in perpendicular relationships. Whatever loses that perpendicularity will be blown away’ (Section 3. The Standard Measure of Truth A true heart does not change. With- out it, a standard cannot be set and things cannot be evaluated by saying, “It is this way” or “It is that way.” You will not have the root that makes it possible to receive official approval according to).
Applied to persons: the true person ‘should be the standard of whom it can be said, He is accurate and true, both vertically and horizontally, and is free of distortion.’ This means alignment in four directions (east/west/north/south), front/back, left/right, above/below — and crucially, fitting both the earthly world and the spirit-world. The measurement metaphor is exacting: ‘if it is found to be oversized when measured in millimeters, even by less than one-half of one millimeter, it will be rejected.’
The vertical axis represents the God-human relationship; the horizontal axis represents human-human relationships (husband-wife, parent-child, siblings). A true person sits at the intersection. This sets up the true-parents doctrine: True Parents are those who first achieved this perpendicular alignment, becoming the standard by which all others are measured.
The analogy carries a strong implication for believers-responsibility: members are being asked to align with a precision standard, not approximate it. The standard is exterior (the universal Principle) and any deviation disqualifies. Critics will worry about perfectionism and the impossibility of meeting the standard; SMM’s reply is that True Parents themselves bear the standard and members participate through engrafting onto their lineage. Worth pairing with the formation-growth-completion-stages schema, since perpendicular alignment is the completion-stage state.
