In "How Christ Changed the World--the Social Principles of the Catholic Church", Msgr. Luigi Civardi, the foremost name in the great Catholic Action movement, describes briefly just what sort of changes Our Lord and His Faith have made, most of which people today merely take for granted. The religion of Jesus Christ eventually put an end to slavery, elevated women to equality with men, ennobled children, established the sanctity of marriage and its unity and indissolubility, elevated the workman and gave dignity to manual labor. This book makes it clear that Christ redeemed mankind, not only spiritually, to enjoy forever eternal life with Him and the Heavenly Father, but He redeemed and transformed man's life in this world as well.
