Same faith magic?

[Particle_Man]

Aside from the spell Faith Healing, what other spells or other effects will only work on members of the same faith as the pc originating the spells or other effects?

[Biggus]

Recitation (SpC) only has its full effect on allies who worship the same deity.

Hand of the Faithful (SpC) excludes those who don't worship your deity (unless they wear their holy symbol).

Relics (MIC) have powers which can only be used by someone of the same faith as their creator.

I think there might be one or two divine feats that work this way, although I could be wrong about that.

[Psyren]

For a core example, Hallow and Unhallow's attached spell effect can be made to only apply to creatures that share your faith - or in the case of negative spells, creatures that don't. For example, you could have all creatures who don't share your faith be continuously silenced inside your holy site while yours are free to cast.
