I'd like some feedback on my latest feat. Please let me know what you think. For reference I include the prerequisite feat, divine channeling; Clerics get divine channeling as a class bonus feat at fist level in my homebrew.

Divine Channeling (Divine)
You are able to channel negative or positive energy.
Prerequisite: Able to cast 1st level divine spells
Benefit: You can release a wave of energy by channeling the power of your faith through your holy (or unholy) symbol. This energy can be used to cause or heal damage, depending on the type of energy channeled and the creatures targeted. If you are of good alignment (or worship a good deity) you channel positive energy and can choose to deal damage to undead creatures or to heal living creatures. If you are an evil alignment (or worship an evil deity) you channel negative energy and can choose to deal damage to living creatures or to heal undead creatures. Neutral characters that worship a neutral deity (or if you are not devoted to a particular deity) must choose whether you channel negative or positive energy. Once this choice is made, it cannot be reversed.
Channeling energy causes a burst that affects all creatures of one type (either undead or living) in a 30-foot radius centered on the character. The amount of damage dealt or healed is equal to Xd6 points of damage where X is equal to highest level divine spell that you can cast. Creatures that take damage from channeled energy receive a Will save to halve the damage. The DC of this save is equal to 10 + half the sum of your combined caster levels in all classes that grant divine spellcasting + the character's Charisma modifier. Creatures healed by channeled energy cannot exceed their maximum hit point total—all excess healing is lost.
You may channel energy three times per day. This is a standard action that does not provoke an attack of opportunity. You can choose whether or not to include yourself in this effect. You must be able to present your holy symbol to use this ability.
Last Rites (Divine)
You are able to lay the spirit of a deceased creature permantly to rest.
Prerequisite: Divine Channeling
Benefit: By using your divine channeling you are able to prevent the deceased from being violated into unlife. The number of daily uses of your divine channeling to use this ability depends on your alignment and the alignment of the deceased; if both match only on use must be expended, if the difference is only opposed only one axis two uses must be expended and if the alignment of the deceased is diamterically opposed to yours three uses must be expended. The amount of uses can't be adjusted even if you have Metachanneling Focus as one of your feats.
Special: Creatures killed by undead that would have the creature rise as an undead after death can be prevented as rising from undead, by freeing the spirit of the deceased with the use of this feat. Creatures that already undead cannot be given last rites unless it is first slain and then the body (which in some cases might need to be found and near impossible to do so) can be given last rites. Dead creatures that are the beneficiary of last rites cannot be brought back from the dead by any means short of divine intervention.
Any input would be keen.
Flavor/theme-wise, I like this. But it really is just using your channeling ability to duplicate the effects of sanctify corpse and a few other divine spells. Is this linked to a theme in your game world perchance?
