Angel

He was angel, a limbic knight, a key to souls, symbolic
Light. And life to death, a chapel bell, incarnate life, a
Steeple tale. Lucific shame, a ghostly prayer, a thousand
Years, the tears of flare. And dungeon hell, a vision born,
A psychic knell, a church to mourn. My Morning Star, my
Cryptic Christ, suffuse the fall, the wall of plight. For
Kingdom come, the will of God, a Bishop lives, and
Yearns applaud.

He was angel, a limbic knight, a key to souls, symbolic
Light. And flaming proud, the sin ensued, a haughty hex, a
Haven grew. But flight to fall, a fettered soul, adrift the hells,
To gain control. Thus the fallen, the rite of rain, a rustic
Cage, a raging flame. For Kingdom come, the will of God,
A Bishop lives, and yearns applaud.   

Limbic: The limbic system includes many structures in the cerebral pre-cortex and sub-cortex of the brain. I, here, use the term limbic as a synonym for limbo. Limbo is believed to be a place where souls are housed, such as un-baptized infants, and some that were placed there before the coming of Christ. It is my belief that limbo is an in between state of both life and death, if we are to assume that death, outside of shedding the body, is actually factual.  

Symbol/symbolic: either an idea representing something actually tangible, or an idea, and/or, material object, representing something real and material, or something metaphysical (beyond the realm of physics, such as the Kingdom of God). Symbols point to something else, such as prayer beads (concrete) point to prayer (the abstract).

Incarnate: when a spirit embodies the human form.
Lucific is another word for Lucifer: a Morning Star; light bearer.
Knell: the sound of a bell, especially, during a funeral.
Morning Star: Christ.
Suffuse; to permeate with light.
Rustic: of, or relating to a country side; rural.
