This "Catechesis on the Book of Genesis" was presented by His Holiness in his weekly general
audiences from September 5, 1979, to April2, 1980. Pope John Paul II explains that these reflections " sprang from the answer given by Jesus. to His questioners (Gospel of Matthew 19:3-9; and of Mark10:1-12), who had asked Him a question about marriage, its indissolubility and unity. The Master had urged them to consider carefully that which was 'from the beginning.'
"We, penetrating the simple content of this answer, are trying at the same time to shed light on
the context of that 'beginning' to which Christ referred. The theology of the body has its roots in it.
"Precisely for this reason, in the series of our meditations, we have tried to reproduce somehow
the reality of the union, or rather of the communion of persons, lived 'from the beginning' by the man and the woman.''
