"In our contentious cultural climate, reasonable, friendly dialogue on important issues is becoming a lost art. Through his characters, Peter Kreeft offers a thoughtful and fair-minded exploration of the differing views on the Eucharist among Anglicans, Catholics, and Evangelical Protestants, and in the process, models how to discuss a difficult topic in a gracious and friendly manner."— Holly Ordway, Author, Not God's Type: An Atheist Academic Lays Down Her Arms
"We've all wished that we could be the proverbial fly on the wall. Peter Kreeft makes it possible in this wonderful book, which allows us to listen to an imaginary conversation between C. S. Lewis, J. R. R. Tolkien, and Billy Graham on the thorny topic of the Eucharist. Their imaginary presence enlightens our minds on the Real Presence." — Joseph Pearce, Author, Catholic Literary Giants
"For one riveting evening we are invited to eavesdrop on C.S. Lewis, J.R.R. Tolkien, and Billy Graham. Rarely have I learned so much while being so entertained. Perhaps this book's greatest achievements lie in Kreeft's tender analysis of what unites the different churches, his gift of charitable listening, and his singular ability to illuminate."— Sally Read, Author, Night's Bright Darkness: A Modern Conversion Story

Full of curiosity, insight, and good humor, Symbol or Substance brings twentieth- century heroes to the table to discuss the heart of the matter with loving candor."— Tyler Blanski, Author, An Immovable Feast: How I Gave Up Spirituality for a Life of Religious Abundance
"When I saw that my favorite contemporary author, Peter Kreeft, was writing a book about a conversation between three of my biggest personal heroes, I had very high expectations.
