St. John Vianney
“Thus you imitate the Jews. They are reproached for refusing shelter to Jesus Christ on the first Christmas night although they did not know Him. You treat Him with the same discourtesy, you who neglect to receive Him into your hearts in Holy Communion. Do not forget that at the Particular Judgment Jesus Christ will judge us on all the good we could have done. He will show you all the sacraments that you could have received during your life. How many more times you could have received His Body and His Blood if you had wished to lead a better life.”
