First, numerous non-canonical books are quoted in the New Testament. These include the Book of Enoch and the Assumption of Moses (quoted by St. Jude), the Ascension of Isaiah (alluded to in Hebrews 11:37), and the writings of the pagan poets Epimenides, Aratus, and Menander (quoted by St. Paul in Acts, 1 Corinthians, and Titus). If quotation equals canonicity, then why aren’t these writings in the canon of the Old Testament?
well what about the 300+ scriptures qouted by Jesus and the apostles from the septuigent?
Similarly, St. Paul alludes clearly to Wisdom chapters 12 and 13 in Romans 1:19-25. Hebrews 11:35 refers unmistakably to 2 Maccabees 7. And more than once, Christ Himself drew on the text of Sirach 27:6, which reads: “The fruit of a tree shows the care it has had; so too does a man’s speech disclose the bent of his mind.” Notice too that the Lord and His Apostles observed the Jewish feast of Hanukkah (cf. John 10:22-36). But the divine establishment of this key feast day is recorded only in the deuterocanonical books of 1 and 2 Maccabees. It is nowhere discussed in any other book of the Old Testament. In light of this, consider the importance of Christ’s words on the occasion of this feast: “Is it not written in your Law, ÔI have said you are gods’? If he called them Ôgods,’ to whom the word of God came—and the Scripture cannot be broken— what about the One Whom the Father set apart as His very own and sent into the world?” Jesus, standing near the Temple during the feast of Hanukkah, speaks of His being “set apart,” just as Judas Maccabeus “set apart” (ie. consecrated) the Temple in 1 Maccabees 4:36-59 and 2 Maccabees 10:1-8. In other words, our Lord made a connection that was unmistakable to His Jewish hearers by treating the Feast of Hanukkah and the account of it in the books of the Maccabees as an image or type of His own consecration by the Father. That is, He treats the Feast of Hanukkah from the so-called “apocryphal” books of 1 and 2 Maccabees exactly as He treats accounts of the manna (John 6:32-33; Exodus 16:4), the Bronze Serpent (John 3:14; Numbers 21:4-9), and Jacob’s Ladder (John 1:51; Genesis 28:12)— as inspired, prophetic, scriptural images of Himself. We see this pattern throughout the New Testament. There is no distinction made by Christ or the Apostles between the deuterocanonical books and the rest of the Old Testament.
