Sacred bonus to Armor, Body, and Shields stacking?

[reapersaurus]

I'm pretty sure this is a no, but there's a feat from the NetBook of Feats that goes something like:

DIVINE ARMOR [Divine]
COPYRIGHT 2001, Eric D. Harry
You can channel energy to enhance your body or armor.
Prerequisite: Ability to turn or rebuke undead, Cha 13+,
Divine Vigor, Extra Turning.
Benefit: By spending one of your turn or rebuke undead
attempts, your armor or body gains a sacred (if you channel
positive energy) or profane (if you channel negative energy)
bonus to Armor Class equal to your charisma bonus for a
number of rounds equal to your charisma bonus. When
active, your armor or body glows with divine light (or a
profane aura) in a radius of 5 feet. The bonus provided by
Divine Armor is fully effective against incorporeal creatures.

So if you charge up a +1 large steel shield, getting a +5 sacred bonus to that armor bonus (total of +8), then charge up a suit of Plate Armor with the +5 sacred bonus (total for Full Plate of +13), would your AC be +21, or +16?

The general rule is like bonuses do not stack. Sacred or profane bonuses are not part of the exceptions to this rule, so they would not stack with each other in this example.

THe feat says armor or body, not shield. So I don't think it would work with the shield at all.

The feat is ambiguous. It speaks of a "sacred or profane" bonus which can apply to either the body or armor, which makes it unclear exactly what's going on.

By the core rules (DMG p. 177), "sacred/profane" can only effect overall AC, not an armor's bonus -- only an "enhancement" bonus can do that. If I had to interpret this feat in my campaign, I would have to disregard the "or armor" clause as flavor text, and only apply the bonus directly to AC, per the core definition of "sacred/profane". Hence, no stacking.
