Communion of Saints and Mass

I was reading "The Spirit of Catholicism" by Karl Adam tonight for my Ecumenical Dialogue class tomorrow when I came across the following beautiful description of the Communion of Saints at Mass:

"When, in the Moments of the Mass, in the presence of the sacred Oblation and under the gaze so to speak of the Church Triumphant, she [the Body of Christ] cries to heaven: "Be mindful also, O Lord, of thy servants and handmaids. . . who have gone before us with the sign of faith and rest in the sleep of peace," then truly heaven and earth greet each other, the Church Triumphant, Suffering and Militant meet in a "holy kiss," and the "whole" Christ with all His members celebrates a blessed love-feast (agape), a memorial of their communion in love and joy and pain."
