There are many ways in which parents pass on the great mystery of the incarnation to their children if we are talking about the family: because God came and was born as a baby, it is a children's party and toys are presented to show it, but the real basis of salvation and history is hidden because of these gifts. Parents have a duty to provide information and explanations about what is said in the Holy Scriptures. Catechesis on the Church, the family and development, in collaboration with Fr Bertrand Ratovoalinirina.
