This cluster gathers the attributes that fix God's self-existence and modal-temporal standing: necessity ([§6.3.1](<6.3.1 Necessity.md>)), eternity ([§6.3.2](<6.3.2 Eternity.md>)), immutability ([§6.3.3](<6.3.3 Immutability.md>)), and impassibility ([§6.3.4](<6.3.4 Impassibility.md>)). Each says how the divine being stands to time, change, and dependence: that God exists of itself, outside succession, beyond alteration, and unaffected from without.

Pressed, each requires the structural conditions it was meant to escape — necessary existence, timeless standing, changelessness, and unaffectedness cannot be specified without reintroducing the succession, persistence, and exchange that T, S, and Φ name. Impassibility ([§6.3.4](<6.3.4 Impassibility.md>)) is a boundary-crossing: classified here by attribute-type, its inversion runs on the reach-arm, the demonstration that Nature cannot act on God.
