No, I think we might still disagree.

- as an alternative to the knowledge requirement, you can obtain 'access through another magic item';
- as a further alternative to the knowledge requirement, you can 'access through another... spellcaster'.
In your example, Cleric A cannot fulfill both roles - he or she is not 'another... spellcaster'; he or she is merely 'the item's creator'.
I recognise that we might not agree on the above, so what about the Glyph example I quoted earlier?
Spell Glyph: You can store any harmful spell of 3rd level or lower that you know. All level-dependent features of the spell are based on your caster level at the time of casting the glyph.
I think there really are multiple uses of 'know' in the context of spellcasting in D&D, and it is often used in an imprecise manner:
- there is the ordinary usage (which I say encompasses all spellcasters, and which you say encompasses only arcane spellcasters);
- there is the 'known spell' definition in the glossary of the PHB (which I think is in turn only used in the definition of 'spell completion item');
- there is 'spells known', which is used by Sorcerers/Bards and similar classes.
Even though we disagree about the above, I presume you agree that some Divine spellcasters (e.g. Favoured Souls) absolutely 'know' spells (that is, the PHB definition of 'known spell' is not absolute)?
