It was a council called for by the Emperor to establish a dogma, which can then be enforced as state religion. (Which he then ditched in older age, but that's another issue.)

Well how about Philip the Fair

You realise that the Avignon Papacy is in no way an example of a separation of church and state... not to mention the assembly of French bishops Philip IV called to support his position in that tax debate.

There was never no ayatollah in Europe.

There was, in the Papal State... but you are confusing Iran with Saudi Arabia there. There is no ayatollah with a political position above the Saudi royals -- nor is there in any other Muslim state other than Iran.

You're theorizing and picking what suits you.

...is what I can tell about you. First you take the only non-Christian in the middle of dozens of mad 4th-century Christian Emperors to prove separation of church and state, then take Iran among dozens of Muslim countries as representative (even while the debate got narrowed down on Saudi Arabia after a previous cherry-pick of yours), and you also cherry-pick Philip IV as a(n ill though-out) 'counter-argument' against the generla practice of royal anointment by clergymen (and the principle of religious justification for feudal power that's behind it).

You don't say a word about parliaments and univesities

I could, but what I said suffices to negate your denial of Saudi-style ties between church and state in Chistian countries.

Parliaments emerged as institutions of the feudal class, and similar institutions existed in the Muslim world, too. Their democratisation coincided with the church's loss of influence (something that happened against its own will and with its active opposition), e.g. for example the French Revolution. Universities on the other hand emerged in a religious context, and for a long time participated in establishing and guarding church dogma. (Their roles in combatting 'heresies' is well known, also for example in the case of Joan of Arc.)

Rule of Law

I did in fact refer to laws. Read back. In fact, the rule of law until not long ago in most places and the Saudi situation today is very similar: it exists in theory, but less in practice, with a fight for its application in courtroom cases. In fact, internationally, the rule of law still doesn't hold -- or else, a lot of kidnapping CIA agents, not to mention Bush et al would sit in prison.)
