As in all things that divide Christians, the words social gospel are unfortunately misunderstood. The phrase is not a quote from scripture. However, the concept of a social responsibility towards others is there. One example is that of the selfish rich man in Luke 16:19-31 who was hard-hearted towards poor Lazarus. Another question that Protestants have is whether this passage requires works for salvation. I believe that Protestants and Catholics actually agree on works. The biggest difference is that Protestants see good works resulting from saving faith. Catholics see saving faith evidenced by good works. It’s like splitting hairs, if you ask me. The bottom line is that a social responsibility towards others is clearly evident among those who believe. John told the Pharisees to show fruit of a changed heart. One such fruit is how we treat others.
