Is social action leftist?

To most evangelicals, "social action" as a theological tenet once had liberal, suspicious, and unbiblical connotations. Such "social gospelers" were considered politically left, semi-Christians who had forsaken a biblically based salvation message for a diluted gospel of mere social ethics. And because it was largely the theological liberals who embraced social action, evangelicals reacted by making both liberals and social action their adversaries.

No longer. Over the past few decades, evangelicals have increasingly talked about a holistic gospel that incorporates in its salvation story a Jesus who came into the world to minister to all needs of a hurting humanity--physical and social needs as well as spiritual needs.
