In the message brought by the Virgin, God said to the children of La Salette: "I gave you six days to work; I reserved the seventh for myself but you refuse to give it to me." Thus, we are reminded of the duty to sanctify Sunday.
In 1998, Pope Saint John Paul II issued an Apostolic Letter reminding us of the meaning of Christian Sunday: "Those who have received the grace of faith in the Risen Lord cannot fail to grasp the significance of this day of the week with the same deep emotion which led Saint Jerome to say: Sunday is the day of the Resurrection, it is the day of Christians, it is our day … From the beginning of my Pontificate, I have not ceased to repeat: Do not be afraid! Open, open wide the doors to Christ! In the same way, today I would strongly urge everyone to rediscover Sunday: Do not be afraid to give your time to Christ! Yes, let us open our time to Christ, that he may cast light upon it and give it direction." (Dies Domini, May 31, 1998, 2, 4, 7).
