The phrase “Social Justice” was used by Father Charles Coughlin (1891 – 1979) for his weekly newsletter (1936 – 1942). Distinctly right-wing, Father Coughlin wanted to keep the U.S.A. out of foreign wars. He also wanted to keep the Federal Government out of everyday life. I remember several professors at UCLA in the 1970s who knew of Coughlin and made a point of denouncing him. No one, particularly on the Left, knows of Coughlin nowadays. The irony runs rich.
