“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.” -Pope St. John Paul II
