A child is a creature and a gift of God, which comes to earth through the love of his parents.
True love does not desire a couple to be self contained. Love opens up in the child. A child that has been conceived and born is not something “made”, nor is he the sum of his paternal and maternal genes. He is a completely new and unique creature of God, equipped with his own soul. The child therefore does not belong to the parents and is not their property.
