St. Thomas Aquinas - The Theologian The relationship of faith and reason is under intense scrutiny in an age beholden to the competing claims of fundamentalism and secularism. So called “new atheists” insist that the claims of religion amount to mere superstition, a retrograde holdover from a time long ago. Others insist that the life of faith is a retreat into emotions and subjectivism. St. Thomas Aquinas anticipated these objections and trends and demonstrated that to believe is to think and that the life of the mind is integral to life in Christ.
