While all Christians look forward in eschatological hope for our True Home in the divine perichoresis of the Most Blessed Holy Trinity, known lovingly during the Middle Ages as the Beatific Vision, such essential twentieth century writers as C. S. Lewis and J. R. R. Tolkien acknowledge that our earthly vocations must include doing battle with exemplars of evil whose life and livelihood seem intent on destroying that which is true, good, and beautiful.
Lewis, as I note in this post, expressly states the utter need in extremis to do so. Tolkien, who like Lewis (in so many ways) fought and was wounded in the trenches of World War I, depicted the fight for Middle Earth as a mix and blend of warfare, providence, and bravery the likes of which just barely saved truth, goodness, and beauty by the narrowest of margins.
While contemplation of the Most Blessed Godhead is a vital part of our mission today as followers of Christ, is it all we are called to do? I think not. While in these "shadowlands", as Lewis called our troubled world, we are called to love and forgive even our enemy; but also defend all that we call good through legitimate defense. Occasionally the faithful thing to do is to do one's best to stop destroyers, practicing faith, hope, and charity in so doing.
