Why should Christians bother to read the Old Testament? Why should we have passages from Hebrew Scripture read in services of Christian worship. And why should anyone bother to preach on an Old Testament text in a service of Christian worship?
I have suggested that there are a number of key themes in the books of the Old Testament that resonate strongly within the pages of the New Testament. See https://johntsquires.com/2021/05/24/why-read-study-or-preach-from-the-old-testament/
We need these Old Testament themes from the times of the patriarchs and matriarchs, the judges and sages, the prophets and kings, to make sense of the story of Jesus and the early church that is told in the New Testament.
We explored a cluster of these themes in the previous post: the people of God, in covenant with God, who offers love and mercy, through the gift of the Law. See https://johntsquires.com/2021/05/25/reading-old-and-new-testaments-together-1-people-covenant-law/
In this post, we continue with two more themes: worship, and justice.
Worship sits at the heart of the people in the Old Testament, and this theme continues through into the New Testament. Alongside the focus on the giving of the Law (Exodus 24) as the people were travelling through the wilderness (Exod 15:22 to Num 33:49), there are detailed instructions about building the Tabernacle (Exod 26–31) and about the liturgical functionings associated with it (Leviticus, and Num 3–11). Later, the building of the Temple becomes prominent (1 Kings 5–8) and the collection of Psalms is made as a rich resource for this liturgical life.
All of these passages, quite clearly, relate directly to the customs and practices of another time and place, far removed from current times, and also distant from the times in which many of the New Testament documents were written. Nevertheless, the Psalms continued to inform the spiritual life of Jesus and his followers (to the point of his death, Mark 15:34 quoting Ps 22:1), and the language of temple is taken up in a spiritualised form (1 Cor 3:16–17, 6:19; Eph 2:19–22; and see the cultic language of Phil 4:18).
Likewise, the death of Jesus is understood to be a spiritualised sacrifice (Gal 1:4; Eph 5:2; 1 Tim 2:6; Titus 2:14; and much of Hebrews), and his followers are encouraged to offer “spiritual worship” (Rom 12:1-2) even whilst they sing “psalms and hymns and spiritual songs” (Eph 5:19; Col 3:16).
However, within the books of the Old Testament, there are many passages critical of the worship practices of the people of Israel. Although the intricate details of prayers, sacrifices and offerings were commanded by the Lord (Lev 1–7; Num 15; Deut 12), many of the prophets are critical of the excessive focus on sacrifices and prayers.
Speaking on behalf of God, Amos thunders a clear denunciation of worship gatherings: “I hate, I despise your festivals, and I take no delight in your solemn assemblies” (Amos 5:21–27). Isaiah berates the people with God’s diatribe, “I have had enough of burnt offerings of rams … I do not delight in the blood of bulls or lambs or goats” (Isa 1:10–17), reinforced by Jeremiah (Jer 6:20) and the Psalmists (Ps 40:6).
Various passages juxtapose the rituals of sacrifice with the divine demand for ethical behaviour. Justice and righteousness is preferred to burnt offerings and noisy songs, says the prophet (Amos 5:21–43) and the sage (Prov 21:3). Another prophet declares that God “desires steadfast love and not sacrifice, the knowledge of God rather than burnt offerings” (Hos 6:6).
A contrite heart, doing the will of God, is preferred to sacrifice and offering, says the Psalmist (Ps 40:6–8, 51:16–17). “To draw near to listen is better than to offer the sacrifice of fools”, says the Preacher (Eccles 5:1). The sacrifice of thanksgiving is what God really requires (Ps 54:6, 116:17). And so the critical dialectic is prosecuted.
A central focus in the Hebrew Scriptures is the commitment to Justice, articulated (as we have seen) by Amos. This is the key quality of the prophetic messages given to Israel over a number of centuries. Moses and the elders he appointed had a responsibility to judge the people (Exod 18:13–27). This was continued by men and women designated as judges in the book of Judges.
Over time, the role of the prophet arose, as judges gave way to kings; the prophet was called to hold the king to account (for instance, Nathan at 2 Sam 12). This then expands so that the prophetic voice speaks truth to all the people, persistently calling out for justice (Amos 5:18–24; Micah 6:6–8; Isa 1:10–17, 5:1–7, 9:6–7, 42:1–4; Jer 21:12, 22:3, 33:15; Ezek 18:5–9, 34:11–16; Zeph 3:5).
This prophetic cry continues into the New Testament, as justice is placed at the centre. Jesus calls for justice (Matt 23:23; Luke 11:42, 18:1–8)—at times, we find it rendered as “righteousness” in his sayings (Matt 5:1-12, 20; 6:33, 21:28–32). This, of course, is the way that it appears in the letters of Paul, where the righteousness of God is the action that we experience when God implements justice in our lives (Rom 3:21–26, 4:1–25; 2 Cor 5:16–21).
Both the manifesto for mission that Luke highlights at the start of the public activity of Jesus (Luke 4:18–21) and the climactic parable of the sheep and the goats that Matthew places at the end of the public teaching of Jesus (Matt 25:31–46) draw strongly from Old Testament insights. Both demonstrate the priority that Jesus gave to practical actions of support, care, and advocacy within ordinary life—precisely what justice is!
Jesus highlights the judgement executed by God (Matt 8:10–12; Luke 13:28–30) and told a number of parables of judgement—particularly those collected in Matthew’s Gospel (Matt 13:36–43, 47–50, 22:1–14, 24:44–25:46). These stories use the threat of divine judgement as a warning against sinful injustice and as a spur to righteous living. Underlying these warnings is the fundamental principle that God’s justice undergirds all (Matt 12:17–20; Luke 18:1–8).
So in the ways that worship is described and criticised, and in the ways that justice is advocated, we see clear lines of continuity and connection between Hebrew Scriptures and New Testament texts.
