Jesus heals on the sabbath: a sign of the dawn of the new creation
The day of the new creation: a comparison of the Christian Sunday with the Old Testament vision of the Sabbath prompted theological insights of great interest. In particular, there emerged the unique connection between the Resurrection and Creation. Christian thought spontaneously linked the Resurrection, which took place on "the first day of the week", with the first day of that cosmic week (cf. Gn 1:15) in the Book of Genesis… This link invited an understanding of the Resurrection as the beginning of a new creation, the first fruits of which is the glorious Christ, "the first born of all creation" (Col 1:15) and "the first born from the dead" (Col 1:18).
In effect, Sunday is the day above all other days which summons Christians to remember the salvation which was given to them in baptism and which has made them new in Christ. "You were buried with him in baptism, in which you were also raised with him through faith in the working of God, who raised him from the dead" (Col 2:12; cf. Rom 6:4-6). The liturgy underscores this baptismal dimension of Sunday, both in calling for the celebration of baptisms — as well as at the Easter Vigil — on the day of the week "when the Church commemorates the Lord's Resurrection", and in suggesting as an appropriate penitential rite at the start of Mass the sprinkling of holy water, which recalls the moment of Baptism in which all Christian life is born.
