I also think Paladinhood should be severed from Priesthood. Paladins are not the defenders of a god's faith. That's what Clerics (with the proper melee theme) are. Paladins are the epitome of knighthood, of the cavalier. Lancelot is a paladin, and he is not the defender of god (Galahad might be, but Lancelot is not, for sure. Christianity does not allow adultery).
You're right in that Lancelot wasn't a "Defender of the Faith," but it is generally accepted that he was granted his extraordinary skill due to his faith in God. As far as the adultery thing goes, the story of Arthur started out primarily as propaganda, but as the years went on, it became more romanticized and took on tragic tones. It was less about the "strength of a nation" and more about "the loss of a nation" (Lancelot falls, the table is forgotten, etc...).
[*and Christianity has interesting views on adultery depending on whether you're reading the old or new testament - but that's a topic for a different forum (;]
But I'm with you in that Paladin's shouldn't be priests. They shouldn't be the ones evangelizing and proselytizing - they should just be dedicated and, to borrow a religious term, perhaps "transfigured" through their dedication: a paragon of what they believe is good.
When I think Paladin, I think about Galahad, Lancelot, Gawain, Charlemagne, even Don Quixote. One could argue that Miyamoto Mushashi, D'artagnan and Jason are also paladins, from diferent settings or ages.
I think of Galahad, Lancelot, and Charlemagne as well - but as the
classic Paladin. These are the +5 Holy Avenger paladins with the aura of protection from evil (e.g. 1st ed AD&D). Don Quixote, is more of the latter version of a Paladin in that he isn't religious (far from it, in fact), but he was dedicated to an
ideal. Jason could be a different kind of Paladin, one that is dedicated to a quest or even just the concept of "questing." His is a life of aspiring for the unachievable - so to speak.
I think all of these can fall under the category of a Paladin and could be expressed through different themes (either developed by the designers or by players and their DM). I think we just need a core Paladin that is flexible enough for players to accommodate those choices without losing a sense of verisimilitude in regard to the base, Paladin archetype. [/quote]
They don't need spells. Give them abilities, sure. But no need for spells. Smites, auras, challenges, bonds with his weapon/armor/shield/mount (chosen by the PC maybe), Lay on Hands, sacrifice for the others, etc give more than enough room to make them interesting *and different* from level 1 to 20/30.
I'm not crazy about Paladins casting spells, but I like the idea of them being able to do spell-like things or possess special abilities. For example, the "Galahad-esque" who is "righteous" may have the ability to receive revelation from his deity (augury, clairvoyance, divination, etc...). The "Don Quixote" type might be able to withstand more punishment than the typical warrior (e.g. endurance, resistance, or DR), or something along those lines.
