That's simplisitc. You commonly refer to agreement of beliefs, as in
"Do you believe 2+2=4?" Science is only possible because people can
agree on facts. The account of how Alfred Russell Wallace tried to
prove that the Earth is round to the head of the Flat Earth Society
is a cautionary tale about that.
Only when we bet that there is reality, which is science only when
metaphysics is done with the scientific method, but the scientist will
not start with “do you believe that 2+2=4”. He will give some axioms, like
0 ≠ s(x)
s(x) = s(y) -> x = y
x = 0 v Ey(x = s(y))
x+0 = x
x+s(y) = s(x+y)
x*0=0
x*s(y)=(x*y)+x
And make reasoning from that, without addressing question of belief.
For example, if someone say that he disagrees with the third axioms,
the teacher, say, will say to wait when they will study an
axiomatisation of all integers, but that today they axiomatise only
the non negative integers.
Now, we can agree or disagree on the applicability of a theory, when
used informally. But in “serious theology”, we use the axiomatic
method, and there is no disagreement possible, as when you do theology
scientifically, your own private opinion in the matter is kept silent.
The contemporary disagreement in theology just comes the fact that
since 1500 years, we are just not allowed to use reason and methodical
verification in that field. We tolerate the argument of authority
since long, or we have no choice, or become dissident, etc.
But a scientific theory does not consist of axioms alone (or even
mostly). It must also include interpretations to connect it to
observation. So it is literally meaningless to say you have derived
science by an axiomatic method.
