DOGMA AND AXIOM.

It appears important to distinguish between `dogma` 
and `axiom`.  Axiom is a statement accepted as 
root of a theory, without deductive apriori proof. 
However, its validity is limited and RELATIVE 
to that theory and it is subject to inductive, 
a posteriori proof. Any rational theory  has 
to be justified by conformity of its theorems 
(or axioms by inference) with expected deductive 
or experimental results.

Experimental: axiom of Ether has been introduced 
IN ORDER to found a theory consistently coordinating 
and predicting the behavior of light. Its nature 
is TELEOLOGICAL, it is RELATIVE to its author`s 
objective. Its validity is RELATIVE and limited 
to the `Ether Model` and it is UNCERTAIN as 
subject to a posteriori experimental verification 
of deduced theorems. MM experiment contradicted 
one and, consequently, the axiom and the theory 
were scrapped. 

Deductive: Since the discovery of Russell`s 
Paradox most of research in the Set Theory dealt
with elimination of Antinomies. Successive, 
carefully chosen axioms have been added and the
free of Antinomies ZF version created. This 
result justifies a posteriori the axioms.

To resume:
Axiom is teleological and thus RELATIVE to 
  author`s objective,
Axiom is RELATIVE to theory,
Axiom has to be PROVED a posteriori.
Conclusion:
AXIOM IS RELATIVE AND DEBATABLE.

Dogma, on the contrary is ABSOLUTE AND FIXED. 
Discuss Mary`s Virginity, let alone call it in
question, is blasphemous. Your opponent is not 
wrong, he is evil, you do not try to convince him,
nor to argue; you fight him; fight with such arms 
as the current state of the involved Inquisition
makes available: 
Demagogy, Stakes, Holy War, Genocide.
