Thomas Merton on attending Mass at Gethsemani monastery on his first visit:
See Who God is! Realize what this Mass is! See Christ here, on the Cross! See His wounds, see His torn hands, see how the King of Glory is crowned with thorns! Do you know what Love is? Here is Love, here on this Cross, here is Love, suffering these nails, these thorns, that scourge loaded with lead, smashed to pieces, bleeding to death because of your sins and bleeding to death because of people that will never know Him, and never think of Him and will never remember His Sacrifice. Learn from Him how to love God and how to love men! Learn of this Cross, this Love, how to give your life away to Him.
See, see Who God is, see the glory of God, going up to Him out of this incomprehensible and infinite Sacrifice in which all history begins and ends, all individual lives begin and end, in which every story is told, and finished, and settled for joy or for sorrow: the one point of reference for all the truths that are outside of God, their center, their focus: Love.
Do you know what Love is? You have never known the meaning of Love, never, you who have always drawn all things to the center of your own nothingness. Here is Love in this chalice full of Blood, Sacrifice, mactation. Do you not know that to love means to be killed for glory of the Beloved? And where is your love? Where is now your Cross, if you say you want to follow Me, if you pretend you love Me?
