The Eucharistic miracle of Montserrat brings us to reflect on the reality of purgatory and reminds us that every Mass has an infinite value because it makes the unique sacrifice of Christ suffering on Calvary present in our minds. This Eucharistic prodigy is reported by the Benedictine priest R.P. Francio de Paula Crusellas, in his text, New History of the Sanctuary and Monastery of Our Lady of Montserrat.
