Apparently you have been taught differently than I have been (and I have never gone to a religious school). I was taught that there is a distinct difference between scientific theory and law. Law can be observed and is therefore worthy to be unconditionally believed.
A scientific law "is a statement that describes regular or patterned relationships among observable phenomena." It need not be unconditionally believed. Newton's Laws of Motion are a good example; they do not work well under all circumstances.
