Theology of the body (TOTB) is a reference to 129 lectures that Pope John Paul II gave between 1979 and 1984. The work covers a variety of different issues but is mainly centred on God’s plan for life and love and the truth about God’s design for human sexuality. One of the most important points John Paul makes is that the body alone is capable of making the invisible visible, and thus spiritual qualities are made visible by the body.
