Pope John Paul II describes this connection to the end things as a “tension.” Not a surprise. We all know of the Catholic need for a certain surety about the Eucharist. That the liturgy might be merely a means to a greater end places some disquiet in some believers. But the Eucharist, as celebrated on Earth, also has a firm and undeniable connection to the adoration and worship of God in heaven by the saints and angels, as we read today:
19. The eschatological tension kindled by the Eucharist expresses and reinforces our communion with the Church in heaven. It is not by chance that the Eastern Anaphoras and the Latin Eucharistic Prayers honour Mary, the ever-Virgin Mother of Jesus Christ our Lord and God, the angels, the holy apostles, the glorious martyrs and all the saints. This is an aspect of the Eucharist which merits greater attention: in celebrating the sacrifice of the Lamb, we are united to the heavenly “liturgy” and become part of that great multitude which cries out: “Salvation belongs to our God who sits upon the throne, and to the Lamb!” (Rev 7:10). The Eucharist is truly a glimpse of heaven appearing on earth. It is a glorious ray of the heavenly Jerusalem which pierces the clouds of our history and lights up our journey.
