4. Until quite recently, it was easier in traditionally Christian countries to keep Sunday holy because it was an almost universal practice and because, even in the organization of civil society, Sunday rest was considered a fixed part of the work schedule. Today, however, even in those countries which give legal sanction to the festive character of Sunday, changes in socioeconomic conditions have often led to profound modifications of social behaviour and hence of the character of Sunday. The custom of the "weekend" has become more widespread, a weekly period of respite, spent perhaps far from home and often involving participation in cultural, political or sporting activities which are usually held on free days.
This social and cultural phenomenon is by no means without its positive aspects if, while respecting true values, it can contribute to people's development and to the advancement of the life of society as a whole. All of this responds not only to the need for rest, but also to the need for celebration which is inherent in our humanity. Unfortunately, when Sunday loses its fundamental meaning and becomes merely part of a "weekend", it can happen that people stay locked within a horizon so limited that they can no longer see "the heavens".(7) Hence, though ready to celebrate, they are really incapable of doing so.
The disciples of Christ, however, are asked to avoid any confusion between the celebration of Sunday, which should truly be a way of keeping the Lord's Day holy, and the "weekend", understood as a time of simple rest and relaxation. This will require a genuine spiritual maturity, which will enable Christians to "be what they are", in full accordance with the gift of faith, always ready to give an account of the hope which is in them (cf. 1 Pt 3:15). In this way, they will be led to a deeper understanding of Sunday, with the result that, even in difficult situations, they will be able to live it in complete docility to the Holy Spirit.
