Frank Beckwith has a new article published in Touchstone Magazine called "Vatican Bible School" that is really excellent.
Frank writes, "Today, although not agreeing on every policy or program, Evangelicals have become close cultural and political allies to theologically and morally conservative Catholics. Both sides embrace a common philosophy that informs our understanding of the good, the true, and the beautiful."
Frank goes on to discuss the role good and bad philosophies in interpreting the Bible, and therefore the importance of developing a philosophy that leads to an accurate understanding of the Scripture. "The classical view of God was developed not merely because its defenders thought it the most accurate picture of the biblical God. It was developed because they thought it consistent with an understanding of the sort of Being deserving of the name "God" who at the same time is able to perform the actions ascribed to him in Scripture. "
Frank further delves into a common cause that Protestants and Catholics share. "According to John Paul, a democratic regime, whose purpose is to do justice by treating all human beings under its authority with equal regard, cannot do so without embracing certain fundamental moral truths as foundational to its institutions and laws: 'the dignity of every human person, respect for inviolable and inalienable human rights, and the adoption of the ?common good? as the end and criterion regulating political life.'"
Despite many significant theological differences that can't be ignored, Protestants and Catholics share a worldview. "For this reason, we should enthusiastically plumb the many resources in the other's tradition with which we can nurture our souls and sharpen our minds."
