Every moment of Jesus’ life has an eternal meaning: it is taken up into his eternity and represents not only his abiding in his Mother’s womb but also his dying on the Cross and his Resurrection. He is now, simultaneously, everything that he could then be only within temporal succession. This is why Mary, too, eternally remains in the situation of the Pregnant Woman—like the envelopment through which alone Christ operates—and also in the situation of the Woman Giving Birth and of the Mediatrix of Graces. In this form of Christ’s “omnitemporality”, we can see something of our own form of existence in eternity.
