Both names for the enemy are fine, there are different circumstances

What if en-e-my (within me) isn't circumstantial, but central?

The larp is things like "Church of..."

What if church implies the body of christ (each anointed one)? What if entering any suggested church makes one "alike" instead of "apart" from one another?

not it the surface sense

Aka not external (circumferential) but internal (central)...

we call the enemy

We implies one among many, enemy implies within one...joining the former makes it harder to disassemble the latter. Others suggest "we" to tempt one into circumference, and "enemy" to distract one from center.

the same core concept.

The core of sameness (inception towards death) implies differentiation (life), hence core/cor - "heart".
