215. The Kenyan Bishops have observed that “many [young people] concentrate on their wedding day and forget the life-long commitment they are about to enter into.” (Kenya Conference of Catholic Bishops, Lenten Message (18 February 2015) They need to be encouraged to see the sacrament not as a single moment that then becomes a part of the past and its memories, but rather as a reality that permanently influences the whole of married life.(Cf. Casti Connubii) The procreative meaning of sexuality, the language of the body, and the signs of love shown throughout married life, all become an “uninterrupted continuity of liturgical language” and “conjugal life becomes in a certain sense liturgical”.(John Paul II, Catechesis (4 July 1984), 3, 6)
Encouragement to see the wedding day as a liminal experience: something that signals a new existence and an event that prepares the human person for the journey ahead.
