Pope John Paul II gave a series of talks from 1979-1984 that were compiled into a book called "Theology of the Body" which discusses the human body and sexuality. The theology of the body studies God as revealed through our bodies, and how He created us male and female to image His love. It explores how in marriage we participate in a relationship with Christ the Bridegroom by giving our total self as a sincere and fruitful gift to our spouse.
