9. Sunday, the Lord's Day, on which the Resurrection of Christ is especially commemorated, is at the heart of liturgical life as the "foundation and nucleus of the whole liturgical year"²⁵. There is no doubt that considerable pastoral effort has been expended to bring people to rediscover the value of Sunday. Yet it is essential to make a point of this, for "the spiritual and pastoral riches of Sunday, as it has been handed on to us by tradition, are truly great. When its significance and implications are understood in their entirety, Sunday in a way becomes a synthesis of the Christian life and a condition for living it well"²⁶.
