Catholics should be wary of adopting the latest scientific discoveries, or even much of modern scientific dogma, in defense of the Faith. (I am thinking specifically of certain teachings concerning cosmology, general physics, and of course, biology [evolution].) If such dogma is ever successfully shown to be false to the masses, it will discredit Christianity in the minds of skeptics, who might react, "Those Christians knew that their myths and fairy tales had no rational basis, and so they had to use science to justify their religion." (I was reminded of this again when Tim Staples recently said on Catholic Answers Live that the Big Bang theory confirmed Catholic teaching on Creation, when it doesn't.)

Another recent guest was talking about the importance of logic for the Christian apologist -- it might have been Patrick Madrid. Unless they have a strong background in science, apologists should limit themselves to being critical of current scientific dogma, instead of adducing positive arguments for the Faith from the above areas of science. Even the task of harmonizing these scientific "truths" with the Faith may be too much, as it gives claims by scientists more credibility than is usually warranted.
