St. John Vianney on the Holy Mass

The Infinite Mass causes the whole heavenly court to rejoice. It alleviates the pain of the souls in purgatory. It draws down all types of blessings upon earth, and gives more glory to God than all the sufferings of all the martyrs together, more glory than the penances of all the saints, than all the tears shed by them since the beginning of the world and all that they may do till the end of time.
