Then He said to them, “O foolish ones, and slow of heart to believe in all that the prophets have spoken! Ought not the Christ to have suffered these things and to enter into His glory?” And beginning at Moses and all the Prophets, He expounded to them in all the Scriptures the things concerning Himself. (Lk 24:25–27)
All things that are read from the Holy Scriptures in order to our instruction and salvation, it behooves us to hear with earnest heed. Yet most of all must those things be commended to our memory, which are of most force against heretics; whose insidious designs cease not to circumvent all that are weaker and more negligent. Remember that our Lord and Savior Jesus Christ both died for us, and rose again; died, to wit, for our offenses, rose again for our justification. Even as you have just heard concerning the two disciples whom He met with in the way, how “their eyes were restrained that they should not know Him:” and He found them despairing of the redemption that was in Christ, and deeming that now He had suffered and was dead as a man, not accounting that as Son of God He ever lives; and deeming too that He was so dead in the flesh as not to come to life again, but just as one of the prophets: as those of you who were attentive have just now heard their own words. Then “He opened to them the Scriptures, beginning at Moses,” and going through all the prophets, showing them that all He had suffered had been foretold, lest they should be more staggered if the Lord should rise again, and the more fail to believe Him, if these things had not been told before concerning Him. For the firmness of faith is in this, that all things which came to pass in Christ were foretold.… Whereby shall we believe, but by that whereby it was His will that even those who handled Him should be confirmed? For He opened to them the Scriptures and showed them that it was appropriate for Christ to suffer, and that all things should be fulfilled which were written of Him in the Law of Moses, and the Prophets, and the Psalms. He embraced in His discourse the whole ancient text of the Scriptures. All that there is of those former Scriptures tells of Christ; but only if it find ears. He also “opened their understanding that they might understand the Scriptures.” From which we also must pray for this, that He would open our understanding.
Augustine, Homily on 1 John 2:12–17
