Ok, and in this "reduced reaction", Barium Fluoride would not be
considered an 'oxide'.. ? correct ?

Two linked reactions: One is "oxidized"; the other is "reduced".

Oxidation - Definition -> Combining a substance with oxygen.

Strictly speaking oxidation is the loss of electrons. The electrons
need somewhere to go so something is going to gain electrons and that is
the reduction part. So to undergo oxidation, something has to be
reduced - usually it's oxygen that accepts the wayward electrons but it
doesn't always have to be so.

For example:
Ba + F2 -> BaF2 is an oxidation-reduction reaction that doesn't involve
oxygen. Here F is the oxydizing agent.
