What if you were the reason a person refused to come back to Christ? What if your self-righteous, judgemental, dogmatic, theologically correct attitude repelled a soul from accepting Church teaching, from reconciling with the Church, from faith itself? What if they were just on the edge of conversion and one of your contemptuous sneers, caustic remarks, or hostile snubs drove them away? That is one aspect of what Jesus is talking about when he warned against "scandalizing one of these little ones".Source
