"Gratitude is the first sign of a thinking, rational creature."—Blessed Solanus Casey, OFM Capuchin  I’ll buy some of that.  “Here I am, Lord; I come to do your will (Psalm 40:8a and 9a).  “the gracious gift of the one man Jesus Christ overflow for the many” (Romans 5:15b).  Gratitude for Jesus Christ and for fellowship with those filled with his grace, praise God.  “Blessed are those servants whom the master finds vigilant on his arrival” (Luke 12:36), that means being a thinking, rational creature, well beyond  pay-pray-and-obey.”  Liturgy of the Word, Reading 474, Tuesday of the Twenty-Ninth Week in Ordinary Time I.
