How can I explain the Eucharist is not just a symbol? Scriptural apologist John Martignoni hosts “EWTN Open Line—Monday” to take these and other questions, like: What did Jesus mean when He said: “Get behind me, satan.” Why does the Catholic Church not agree with Sola Scriptura. Why do we identify ourselves as “Roman Catholics?” Is it okay to have grape juice instead of wine, for consecration? Are women supposed to have our heads covered all the time?
