St. John Vianney - Saint of the Confessional
I think that God gives His priests the biggest hearts. Because in the confessional we are each given a little piece of that heart of a priest. After how many thousands of confessions over a lifetime, each one taking a little piece of their hearts, yet the heart still beats and continues in love to give to the next one to come into the confessional. The heart of a Priest is not diminished by this giving of itself, for each penitent receives the same measure of the heart that reflects God's own heart for the soul seeking absolution.
