Besides, if you had read my other posts, you would have noticed that I specifically noted that people should talk to their DMs in this kind of situation, because there are multiple ways to adjucate this.
I didn't read the rest of your post(s) due to your demonstration of rules knowledge being sub-par at best.
As implied before, Chapters 10 and 11 of the PHB do not apply when there's no such thing as a (non-PrC) Paladin. I ctrl+F's through the FAQ for instances of 'paladin', and found nothing regarding their spell list. So if any of these "numerous examples" actually exist, please cite them.
And that explains why. You don't read the rules, you skim them looking for exactly what you want.
For example, "wizard spell"'s first hit is a FAQ entry explaining a Durid/Wizard cannot spontaneous cast a SNA using his Wizard spell slots despite there being "no exact rules preventing this". Naivety plays a huge part in spellcasting so while a Cleric can sac any spell slot for a Cure spell, this ability is solely part of clerical spellcasting and does not overlap with other spells or spellcasting abilities. Like as I mentioned with gishes and Arcane Spell Failure, having a level in Cleric doesn't override how your Sorcerer Spells work. Even for instance, Quickening Grease as a Wizard doesn't penalize you to a Full-Round action because Grease is a Sorcerer Spell. In all instances, you are casting X spell, where X is the class that granted the spellcasting ability in the first place.
A prime example in the FAQ is found on page 3, or where my scroll wheel took me before I thought to hit the Find keystroke.
A dragon that can cast cleric spells as arcane spells casts such spells as though they were part of the sorcerer class list. You quite literally have your half read no basis interpretation of "can cast X spells" in that entry that you're trying to say matters, but note that underlined section where like the Prestigious Paladin, it's flat out saying the spell set is added to your existing spellcasting.
In a second it says:
"
If the example dragon adds a level of cleric, it would cast sorcerer spells as a 4th-level sorcerer (including any cleric spells it has added to its list of spells known) and would prepare and cast cleric spells and turn undead as a 1st-level cleric. When preparing cleric spells, it could choose any 1st level cleric spell, just as any other 1st-level cleric could.".
Despite functionally "casting 2nd level cleric spells" using it's sorcerer spells, it only truly has 1st level cleric spells which means if a requirement was 2nd level cleric spells, he doesn't meet them. Or, omg ownership matters yet again!
When Battle Blessing comes along and says your Paladin Spells have decreased casting time. It's not talking about your Cleric Spells, it's not talking about your Sorcerer Spells that can cast Cleric Spells. It's talking about Paladin Spell
casting. And you can find examples of the ownership traits in the descriptions of Classes in the base books, PrCs, etc, where it's so commonly implied or stated (such as multieclass rules/examples) and even direct answers in the FAQ leading to a failure to grasp this concept means you simply are not playing the game correctly or will have one hell of a house rule that declared a free for all, both penalizing some traits (can't quicken cure light wounds due to bard), empowering them (battle blessing off wand use), and generally mucking things up (psion/meldshaper mystic theurge anyone?)
