Is metaphysical idealism compatible with Catholicism?

Is metaphysical idealism (matter doesn't exist) compatible with Catholicism? I'm guessing the answer is no, but I'm not sure because I think that "matter doesn't exist" is kind of a meaningless statement and everyone would agree that mind is prior to matter. Obviously nobody is denying that matter exists *in some sense*, so it's hard to see what this actually means because there's nothing to compare it to. You can't say matter exists or doesn't exist in the same way that X exists.
