E25 Q29 30 31 How are the OT and NT related? What does Inspired mean regarding Holy Scripture, and that it is the Word of God?

How are the Old and New Testaments related to each other?
The Old Testament is to be read in the light of Christ, and the New Testament is to be read in light of God’s revelation to Israel. Thus the two form one Holy Scripture, which reveals the
Person of Jesus Christ and his mighty works. As Saint Augustine says, “The New is in the Old concealed, the Old is in the New revealed.” (Augustine of Hippo, Questions in the Heptateuch 2.73; see also Matthew 5:17–18; Luke 24:25–27)
What does it mean that Holy Scripture is inspired?
Holy Scripture is “God-breathed,” for the biblical authors wrote under the guidance of God’s Holy Spirit to record God’s Word. (Deuteronomy 8:3; Matthew 4:4; 2 Timothy 3:16–17; 2 Peter 1:19–21)
What does it mean that Holy Scripture is the Word of God?
The Old and New Testaments are inspired by the Holy Spirit and are therefore the Word of God written. God is revealed in his mighty works and in the incarnation of our Lord, which are made known through the inspired writings of the biblical authors. God “has spoken through the prophets” (Nicene Creed) and continues to speak through Scripture today. (Psalm 33:4–9; Jeremiah 1:9; Ezekiel 2:1–3:4; 1 Thessalonians 2:13; 2 Peter 3:15–16; Hebrews 1:1–2)
