Passion Sunday: "The Truth commandeth us to long for a Fatherland in heaven "

From the Holy Gospel according to John
John 8:46-59
At that time, Jesus said to the multitude of Jews:

Which of you convicts me of sin? If I tell the truth, why do you not believe me? 47 He who is of God hears the words of God; the reason why you do not hear them is that you are not of God.”

48 The Jews answered him, “Are we not right in saying that you are a Samaritan and have a demon?” 49 Jesus answered, “I have not a demon; but I honor my Father, and you dishonor me. 50 Yet I do not seek my own glory; there is One who seeks it and he will be the judge. 51 Truly, truly, I say to you, if any one keeps my word, he will never see death.” 52 The Jews said to him, “Now we know that you have a demon. Abraham died, as did the prophets; and you say, ‘If any one keeps my word, he will never taste death.’ 53 Are you greater than our father Abraham, who died? And the prophets died! Who do you claim to be?” 54 Jesus answered, “If I glorify myself, my glory is nothing; it is my Father who glorifies me, of whom you say that he is your God. 55 But you have not known him; I know him. If I said, I do not know him, I should be a liar like you; but I do know him and I keep his word. 56 Your father Abraham rejoiced that he was to see my day; he saw it and was glad.” 57 The Jews then said to him, “You are not yet fifty years old, and have you seen Abraham?”[a]58 Jesus said to them, “Truly, truly, I say to you, before Abraham was, I am.” 59 So they took up stones to throw at him; but Jesus hid himself, and went out of the temple.

Homily by Pope St. Gregory (the Great)
18th on the Gospels.
Dearly beloved brethren, consider the gentleness of God. He came to take away sins, and He saith Which of you convinceth Me of sin? He Who, through the might of His Godhead, was able to justify sinners, was contented to show by argument that He was not Himself a sinner. But exceeding dread is that which followeth. He that is of God heareth God's words; ye, therefore, hear them not, because ye are not of God. If, then, whosoever is of God heareth God's words, and whosoever is not of Him cannot hear His words, let each one ask himself if he, in the ear of his heart, heareth God's words, and understandeth Whose words they are? The Truth commandeth us to long for a Fatherland in heaven, to bridle the lusts of the flesh, to turn away from the glory of the world, to seek no man's goods, and to give away our own.
