Sermon: On Keeping the Sabbath

Lectionary: Proper 15(A)

Text: Isaiah 56:1-8

The prophetic book of Isaiah that we have is not the work of a single author. Modern scholarship assigns the first 39 chapters to an 8th century BCE prophet. The remainder of the book is a collection of writings divided into two periods. Chapters 40-55 is known as Deutero-Isaiah, or Second Isaiah, and these chapters come from the exilic period of the Jews in Babylon. The last portion, chapters 56-66 known as Trito-Isaiah or Third Isaiah, is best ascribed to the post-exilic period, after the Jews returned to Jerusalem and the surrounding area.

Our reading this morning is from the beginning of this third section. Why is understanding this important? Because during this period, it is hypothesized by scholars that there were competing ideas among the Jews about what it means to belong to God, what it takes belong to the community of God, what faithfulness to God looks like, and why God allowed them to be exiled in the first place.

On one side were those who believed their exile was because their ancestors hadn’t followed closely enough the commands given to them by God and Moses. The remedy and restoration back to God’s favor was recommitting themselves to careful and even rigid obedience to the law. The law proscribed foreigners and those whose reproductive capabilities were compromised (such as eunuchs). Of particular importance was keeping the Sabbath sacred and not profaning it.

On the other side were those who believed their exile was due to their ancestors breaking the covenant. In this respect, and on the surface, this seemed nearly identical to the other side. But the similarities end there. Those in this second group saw that one could keep the law and simultaneously violate its intent. For this group, the keeping Sabbath was critical, but for different reasons.

Let’s look at the two Sabbath commandments. The first is found in Exodus and the second is found in Deuteronomy.

8 “Remember the Sabbath day and keep it holy. 9 Six days you shall labor and do all your work. 10 But the seventh day is a Sabbath to the LORD your God; you shall not do any work—you, your son or your daughter, your male or female slave, your livestock, or the alien resident in your towns. 11 For in six days the LORD made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the LORD blessed the Sabbath day and consecrated it.[1]

In the commandment found in Exodus, the reason given for the Sabbath is creation.

12 “ ‘Observe the Sabbath day and keep it holy, as the LORD your God commanded you. 13 Six days you shall labor and do all your work. 14 But the seventh day is a Sabbath to the LORD your God; you shall not do any work—you, or your son or your daughter, or your male or female slave, or your ox or your donkey, or any of your livestock, or the resident alien in your towns, so that your male and female slave may rest as well as you. 15 Remember that you were a slave in the land of Egypt, and the LORD your God brought you out from there with a mighty hand and an outstretched arm; therefore the LORD your God commanded you to keep the Sabbath day.[2]

In the version found in Deuteronomy, the reason given for the Sabbath is deliverance and freedom from slavery.

Now, I want to re-read portions of Isaiah 56 from the English Standard Version, which translates a key word consistently. Notice the repetition of the word keep (Hb. Shamar) in the following verses.

1 Thus says the LORD: “Keep justice, and do righteousness, for soon my salvation will come, and my righteousness be revealed. 2 Blessed is the man who does this, and the son of man who holds it fast, who keeps the Sabbath, not profaning it, and keeps his hand from doing any evil.

4 For thus says the LORD: “To the eunuchs who keep my Sabbaths, who choose the things that please me and hold fast my covenant…

And the foreigners who join themselves to the LORD, to minister to him, to love the name of the LORD, and to be his servants, everyone who keeps the Sabbath and does not profane it, and holds fast my covenant…[3]

Taken together, according to Third-Isaiah, keeping the Sabbath and holding fast to the covenant is synonymous to keeping justice and righteousness. The point of Sabbath is not the day or arguing and debating what “work” means or does not mean. Rather, it is about caring for all creation with justice and right-relationships (Exodus) and relating to all human beings with justice and equality (Deuteronomy). It is about ensuring that earth is cared for so that it can provide all humanity with its needs. It is about not abusing the earth of its inhabitants. It is about fair distribution of resources so that all can thrive. No one should be overworked and exploited for the benefit of another. No one should have ownership over another.

There are two covenants that pre-date the covenant at Sinai. The earliest is found in Genesis 9, after the Flood event, where God makes a covenant with all life on earth that God will not repeat the destruction of the world through a flood.

The second covenant is made with Abram/Abraham where he is promised land and descendants. The purpose underlying the covenant harkens back to Genesis 12 where God tells Abraham that he will be a blessing to all families of the earth.

The earliest covenants God made included care for all creation and all humans, beginning with Abraham and spreading to all.

Jumping forward to the gospels, we read of several instances where Jesus and the religious interpreters were at odds on the meaning and purpose of the Sabbath.

1 At that time Jesus went through the wheat fields on the Sabbath. His disciples were hungry so they were picking heads of wheat and eating them. 2 When the Pharisees saw this, they said to him, “Look, your disciples are breaking the Sabbath law.”

3 But he said to them, “Haven’t you read what David did when he and those with him were hungry? 4 He went into God’s house and broke the law by eating the bread of the presence, which only the priests were allowed to eat. 5 Or haven’t you read in the Law that on the Sabbath the priests in the temple treat the Sabbath as any other day and are still innocent? 6 But I tell you that something greater than the temple is here. 7 If you had known what this means, I want mercy and not sacrifice, you wouldn’t have condemned the innocent. 8 The Human One is Lord of the Sabbath.”

9 Jesus left that place and went into their synagogue. 10 A man with a withered hand was there. Wanting to bring charges against Jesus, they asked, “Does the Law allow a person to heal on the Sabbath?”

11 Jesus replied, “Who among you has a sheep that falls into a pit on the Sabbath and will not take hold of it and pull it out? 12 How much more valuable is a person than a sheep! So the Law allows a person to do what is good on the Sabbath.” 13 Then Jesus said to the man, “Stretch out your hand.” So he did and it was made healthy, just like the other one. 14 The Pharisees went out and met in order to find a way to destroy Jesus.[4]

In this story we can see once more that care for creation, its creatures, human beings, and human relationships are the reasons for the Sabbath. The Sabbath is supposed to be the embodiment and enlivenment of salvation and restoration.

What Third-Isaiah tells their reader is that this care and concern for creation and created beings is what identifies those who are part of the covenant community and belong to God. Those whose concerns are for social, economic, and environmental justice are already on their way to finding God and entering God’s community.

The Isaiah text highlights the immigrants and the eunuchs as “outsiders” who might be more in tune with God’s ways than the “insiders” who think they know God’s ways.

This challenges us to consider who the “outsiders” might be in our lives whose hearts are turned toward God in the way they relate to the world. They may not profess Christianity; they might not even believe in God. But Isaiah’s text tells us that God is already at work in their lives, leading them toward God’s community.

On the other hand, through the condemnation of pre-exilic prophets and through the experience of Jesus with his contemporary religious leaders, professing beliefs, practicing religious observances, and displaying religious icons has no value if they are not accompanied by justice and actions that promote right-relationships.

I conclude today’s sermon with a few sentences from John Van de Laar in his meditation on today’s passage.

The lives and world we long for are waiting for us if we will only learn the wisdom of the sabbath and allow it to save us. Ultimately, the sabbath is not a religious ritual. It is not a “day of rest” or a quaint, outdated obstacle to our capitalist dreams. It is a way of being that embodies the just, compassionate, and life-giving rhythms of God’s reign.[5]

In the name of God, the Creator,

In the name of God, Incarnate,

And in the name of God, who discomforts our insular and narrow vision of the kingdom of heaven, Amen.
