Dies Domini - Keeping the Lords Day Holy - Parts 26 - 27 - Pope John Paul II

The eighth day: image of eternity

26. By contrast, the Sabbath's position as the seventh day of the week suggests for the Lord's Day a complementary symbolism, much loved by the Fathers. Sunday is not only the first day, it is also "the eighth day", set within the sevenfold succession of days in a unique and transcendent position which evokes not only the beginning of time but also its end in "the age to come". Saint Basil explains that Sunday symbolizes that truly singular day which will follow the present time, the day without end which will know neither evening nor morning, the imperishable age which will never grow old; Sunday is the ceaseless foretelling of life without end which renews the hope of Christians and encourages them on their way.(26) Looking towards the last day, which fulfils completely the eschatological symbolism of the Sabbath, Saint Augustine concludes the Confessions describing the Eschaton as "the peace of quietness, the peace of the Sabbath, a peace with no evening".(27) In celebrating Sunday, both the "first" and the "eighth" day, the Christian is led towards the goal of eternal life.(28)

The day of Christ-Light

27. This Christocentric vision sheds light upon another symbolism which Christian reflection and pastoral practice ascribed to the Lord's Day. Wise pastoral intuition suggested to the Church the christianization of the notion of Sunday as "the day of the sun", which was the Roman name for the day and which is retained in some modern languages.(29) This was in order to draw the faithful away from the seduction of cults which worshipped the sun, and to direct the celebration of the day to Christ, humanity's true "sun". Writing to the pagans, Saint Justin uses the language of the time to note that Christians gather together "on the day named after the sun",(30) but for believers the expression had already assumed a new meaning which was unmistakeably rooted in the Gospel.(31) Christ is the light of the world (cf. Jn 9:5; also 1:4-5, 9), and, in the weekly reckoning of time, the day commemorating his Resurrection is the enduring reflection of the epiphany of his glory.

The theme of Sunday as the day illuminated by the triumph of the Risen Christ is also found in the Liturgy of the Hours(32) and is given special emphasis in the Pannichida, the vigil which in the Eastern liturgies prepares for Sunday. From generation to generation as she gathers on this day, the Church makes her own the wonderment of Zechariah as he looked upon Christ, seeing in him the dawn which gives "light to those who sit in darkness and in the shadow of death" (Lk 1:78-79), and she echoes the joy of Simeon when he takes in his arms the divine Child who has come as the "light to enlighten the Gentiles" (Lk 2:32).
