St. John Paul II's Insight

From Ecclesia de Eucharistia, from Cardinal Burke's book I am now reading.

"This sacrifice [of Calvary] is so decisive for the salvation of the human race that Jesus Christ offered it and returned it to the Father only after he had left us a means of sharing in it as if we had been present there. Each member of the faithful can thus take part in it and inexhaustibly gain its fruits."
