“Here again, we must examine how the thief should be thought worthy of Paradise, seeing that a flaming sword prevents the entrance of the saints. But observe that the word of God describes it as turning about, so as it should obstruct the unworthy, but open a free entrance to life to the worthy.”

“And rightly is the title placed above the cross, because Christ’s kingdom is not of the human body, but of the power of God. I read the title of the King of the Jews, when I read, My kingdom is not of this world. (John 18:36.) I read the cause of Christ written above His head, when I read, And the Word was God. (John 1:1.) For the head of Christ is God. (1 Cor. 11:3.)”

“A most remarkable example is here given of seeking after conversion, seeing that pardon is so speedily granted to the thief. The Lord quickly pardons, because the thief is quickly converted. And grace is more abundant than prayer; for the Lord ever gives more than He is asked for. The thief asked that He should remember him, but our Lord answers, Verily I say unto thee, This day shall thou be with me in Paradise. To be with Christ is life, and where Christ is, there is His kingdom.”

“But it must also be explained how the others, that is, Matthew and Mark, introduced two thieves reviling, while Luke, one reviling, the other resisting him. Perhaps this other at first reviled, but was suddenly converted. It may also have been spoken of one, but in the plural number; as in the Hebrews, They wandered in goat-skins, and they were sawn asunder; (Heb. 11:37.) whereas Elijah alone is related to have had a goat-skin, and Isaiah to have been sawn asunder. But mystically, the two thieves represent the two sinful people who were to be crucified by baptism with Christ, (Rom. 6:3.) whose disagreement likewise represents the difference of believers.”

“(Mor. 18. c. 40.) On the cross nails had fastened his hands and feet, and nothing remained free from torture, but his heart and tongue. By the inspiration of God, the thief offered to Him the whole which he found free, that as it is written, With the heart he might believe unto righteousness, with the mouth he might confess unto salvation. (Rom. 10:10.) But the three virtues which the Apostle speaks of, (1 Cor. 13:13.) the thief suddenly filled with grace both received and preserved on the cross. He had faith, for example, who believed that God would reign whom he saw dying equally with himself. He had hope who asked for an entrance into His kingdom. He preserved charity also zealously in his death, who for his iniquity reproved his brother and fellow-thief, dying for a like crime to his own.”

“(Mor. 12. c. 9.) Or that flaming sword is said to be turning, because that He knew the time would come when it must be removed; when He in truth should come, who by the mystery of His incarnation was to open to us the way of Paradise.”

Bede the Venerable Patristic
c. A.D. 672–735
“For as many of us as were baptized in Christ Jesus, were baptized in His death; but we are washed by baptism, seeing we were sinners. But some, in that they praise God suffering in the flesh, are crowned; others, in that they refuse to have the faith or works of baptism, are deprived of the gift which they have received.”

“Observe a second time the device of the devil turned against himself. For in letters of three different characters he published the accusation of Jesus, that in truth it might not escape one of the passers by, that He was crucified because He made Himself King. For it is said, In Greek, Latin, and Hebrew, by which it was signified, that the most powerful of the nations, (as the Romans,) the wisest, (as the Greeks,) those who most worshipped God, (as the Jewish nation,) must be made subject to the dominion of Christ.”

“And as every king who returns victorious carries in triumph the best of his spoils, so the Lord having despoiled the devil of a portion of his plunder, carries it with Him into Paradise.”
“This however is more true than all, that although they have not obtained all the promises, I mean, the thief and the other saints in order that without us they might not be made perfect, (Heb. 11:40.) they are notwithstanding in the kingdom of heaven and Paradise.”

“A superscription - See Mat 27:37. In letters of Greek, and Latin and Hebrew - The inscription was written in all these languages, which were the most common, that all might see the reason why he was put to death. The inscription was written in Greek, on account of the Hellenistic Jews, who were then at Jerusalem because of the passover; it was written in Latin, that being the language of the government under which he was crucified; and it was written in Hebrew, that being the language of the place in which this deed of darkness was committed. But, by the good providence of God, the inscription itself exculpated him, and proved the Jews to be rebels against, and murderers of, their king. See the note on Mat 27:37. It is not to be wondered at that they wished Pilate to alter this inscription, Joh 19:21, as it was a record of their infamy.”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
