By Eric Sammons, Catholic Answers - So what should be the invitation of the Catholic evangelist, if it’s not to pray the Sinner’s Prayer? This will vary, depending on the person we’re evangelizing. Right now, let’s look at evangelization efforts directed only toward fallen-away Catholics. Why? Because they are often the “low-hanging fruit” for evangelization since they already have a connection to the Church. And, sadly, they make up the second-largest religious group in America, so there is a lot of work to do.
