Under our current science the very nature that defines a things is by its molecular makeup, are you saying we must reject the current understanding of atoms and how they work?

The distinction between substance and accidents is a metaphysical one.

Physically, scientifically, we are only concerned with accidents. Spiritually, we can discuss both.

I accept the scientific understanding of atoms/molecules (within reason -- there's a lot we don't know, quantum theory has not been completely worked out, etc) but it has nothing to do with substance.

"Our current science" only says that the very nature of things is it's molecular makeup (or whatever it's lower level structure is) only because scientists are concerned with accidents. They (scientists) speak of the nature of an object as it's accidents, including it's structure, mass, shape, whatever.  They do not consider the substance at all.

Remember substance defined metaphysically (Aristotle, Aquinas) is not the same thing at all as substance as in chemical substance.
