Prof. Jonathan I.

Dr. Timothy P. Flanigan, M.D., presents Catholic faith and medicine as profoundly harmonious, showing how Christ’s person‑to‑person healing, the Church’s hospital tradition, and a “culture of life” can and must be lived inside today’s secular, therapeutically focused healthcare system—precisely where pressures over abortion, assisted suicide (MAID), and gender interventions create the sharpest conflicts of conscience.

Prof. Lawrence M. Principe argues that the supposed “war” between science and faith is largely a modern myth, constructed in the late 19th century by figures like John William Draper and Andrew Dickson White for personal, political, and ideological reasons, then amplified by secularizers, technocratic utopians, and bad theology (especially “God‑of‑the‑gaps” arguments and naive literalism) on the religious side.
