Dies Domini - Keeping the Lords Day Holy Parts 5 - 7 - Pope John Paul II
It is also true that both in mission countries and in countries evangelized long ago the lack of priests is such that the celebration of the Sunday Eucharist cannot always be guaranteed in every community.
6. Given this array of new situations and the questions which they prompt, it seems more necessary than ever to recover the deep doctrinal foundations underlying the Church's precept, so that the abiding value of Sunday in the Christian life will be clear to all the faithful. In doing this, we follow in the footsteps of the age-old tradition of the Church, powerfully restated by the Second Vatican Council in its teaching that on Sunday "Christian believers should come together, in order to commemorate the suffering, Resurrection and glory of the Lord Jesus, by hearing God's Word and sharing the Eucharist, and to give thanks to God who has given them new birth to a living hope through the Resurrection of Jesus Christ from the dead (cf. 1 Pt 1:3)".(8)
7. The duty to keep Sunday holy, especially by sharing in the Eucharist and by relaxing in a spirit of Christian joy and fraternity, is easily understood if we consider the many different aspects of this day upon which the present Letter will focus our attention.
Sunday is a day which is at the very heart of the Christian life. From the beginning of my Pontificate, I have not ceased to repeat: "Do not be afraid! Open, open wide the doors to Christ!".(9) 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. He is the One who knows the secret of time and the secret of eternity, and he gives us "his day" as an ever new gift of his love. The rediscovery of this day is a grace which we must implore, not only so that we may live the demands of faith to the full, but also so that we may respond concretely to the deepest human yearnings. Time given to Christ is never time lost, but is rather time gained, so that our relationships and indeed our whole life may become more profoundly human.
