Many have considered that one of Christianity’s greatest weaknesses is that it surrenders social life into the hands of godless secularists.
Christianity has failed in the past few centuries to provide a blueprint for socio-political life in the West.
Socio-political involvement has proved to be effective in the U.K. by Christian politicians like William Wilberforce (abolition of slavery) and Lord Shaftesbury (elimination of child labour).
Jesus said, "Render to Caesar what is Caesar's" (Mat 22:21); this has been commonly misinterpreted to mean socio-political indifference on the part of Christians.
