Karol Wojtyla On Imago Dei

‘In affirming that the spouses, as parents, cooperate with God the Creator in conceiving and giving birth to a new human being, we are not speaking merely with reference to the laws of biology.  Instead we wish to emphasize that God himself is present in fatherhood and motherhood quite differently than he is present in all other instances of begetting on earth.  Indeed, God alone is the source of the ‘image and likeness’ which is proper to the human person, as it was received at Creation.  Begetting is the continuation of that creative event.”  Familiaris Consortio 1981
