In the first reading we have a very good illustration of a successful approach to delivering bad news when you are a prophet and that is your job. The book of Isaiah has been heavily edited, and our reading from chapter 5 is very likely the first public appearance of the prophet. If you want the crowd to listen to you, you don’t want to be known as a prophet of doom. So Isaiah draws a crowd by saying he is going to sing a song, like a street busker setting up his spot. It’s a song, he says, about his friend; it’s told as though it is about a man setting up a new vineyard, but it is really about unrequited love. He did everything one should for the vineyard to be successful, but it just produced (literally) stinking grapes. The friend then questions the crowd: “is there anything more I could have done?” And he tells them he is going to completely wreck the area and make it a wasteland. Then, when the crowd has grown and is listening intently, like a punch-line the prophet announces: “this song is about the Lord and you Israel!” The image of the vineyard became quite popular in the sayings of prophets and even among the people themselves; one of their hymns is the psalm that follows the reading for today.

The first reading is part of a heart-warming poem. It was written about the time that the people were going to be released from captivity by a friendly emperor, Cyrus. It attributes this release to the love of God, who has a special relationship of love for people, a relationship traditionally called a covenant. It is a two-way agreement: God will look after the people, and the people will live in a way pleasing to God. But the agreement is not conditional; it is not like God saying ‘if you keep my commandments I will be your protector and god;’ it is unconditional on God’s side: ‘I will be your God, so you will be my people however you respond to me.’ In the part of the poem we read today, the prophet is announcing to the people, God’s call to them; it is a call to give up any wickedness and turn their lives towards Him. But the prophet is also emphasising that God’s ways are mysterious, for He does not depend on the people behaving well for Him to love them and to be their God; there is no way they can deserve or merit God’s love, it is generous, free and everlasting. The extract is chosen for this contrast between God’s ways and ours, an idea taken up in the Gospel reading for today.

Reading Ezekiel we must remember that the Jews believed that they were the chosen people of the one and only God, Yahweh; they had laws and rules to live by and a covenant which they often thought of as ‘if we keep your laws, God, you will see that we prosper.’ Yet this arrangement didn’t seem to be working out in their history, especially when they were being taken over by a neighbouring empire. So much so that they began to think that they were being punished by God or even would die because of the sins of their ancestors; indeed they attributed all the difficulties and hardships of life to the original disobedience of the first humans ( Genesis 3 ), and they had a saying: “The parents have eaten sour grapes, and the children’s teeth are set on edge.” Ezekiel was trying to replace this idea with the fairness and mercy of God. Not only was God punishing the wrongdoer for his own sins and blessing the good, but saying that there would be forgiveness and blessing if the sinner repented and turned away from sin.

The reading from the Book of Sirach is making the wise and useful observation that God will deal with us in a manner similar to the way we deal with other people. So love and forgive others and God will love and forgive you. But if you… (you know what follows)

God speaks harsh words to Ezekiel the prophet. For Ezekiel knows the harsh things he should be saying to his fellow Jews, and that this will be for their own good in the long term. But who likes to tell others off? So God actually threatens him with punishment if he does not speak out when he knows that he should.

It's not so long ago that we were reading of Elijah wanting to die because of his failure to inspire the people and because of a death-threat against him. Jeremiah was in a worse situation in Judah around the 7th century BC. In that land, regard for Yahweh and the Covenant was almost entirely abandoned, and God urged Jeremiah to preach about the inevitable political demise and eventual national disaster. He had a respite from his work for a short time during the reign of Josiah; for this king tried to reintroduce the recognition of the Law of God as found written in what we now see as the early books of the bible, especially Exodus, Leviticus and Deuteronomy. But this reform soon failed, and idolatry and fertility cults regained popularity. Despite extreme reluctance, Jeremiah began the work of his calling, which was to bring him general disfavour, occasional imprisonment or confinement and continued unpopularity. There was some upbeat aspects to his message at times, particularly the one about God wanting to set up a new covenant within the hearts of the people. He suffered a tormenting turmoil in his own life; it resulted both from his natural abhorrence of preaching against his own people and from the deep and inescapable inner compulsion to undertake the vocation given him by God – announcing the people's downfall. Doing God’s will is not always an obviously good thing! Our reading is his outcry at this personal conflict within him.

During the time of the prophet Isaiah, the kingdom of Judah was threatened by the Assyrian empire from the east. Isaiah had recommended trusting in God to save the people and God would be with them. But the king and leaders didn’t see it this way, they felt they would loose, and forfeit their privileged positions, if not their lives. They made some sort of a pact with the emperor of Assyria so that Jerusalem was spared, although the rest of the country was invaded. So Isaiah, as we read today , reprimand Shebna the royal steward, and announced a replacement, who will be the leader to make decisions in the future; he will have the symbols of office, the sash, the robe, the key to the ordering of the country’s affairs, and will keep them safe like the peg for a tent. This passage seems to be in the mind of Matthew when he writes of Peter receiving the leadership office in our gospel reading. But the historical events behind it challenge us severely in our relationship with our world and with God, just as the sermon on the mount in the New Testament does: if anyone wants your shirt give them your coat as well, if anyone strikes you turn the other cheek, love you enemies… (see Matthew 5:38-48).

There was much apocalyptic literature in the centuries before and after Christ – among the Greek, Roman, Egyptian, Persian and even Indian literature. This literature which is about the development in the world of disasters and troubles expressed in dramatic stories, included those of evil ‘influences’ seeking to destroy the next ruler born to a chosen woman to be mother of the future ruler. Some form of these apocalyptic stories were part of Jewish literature – as also the book of Revelation in the N.T. which used to be called the Apocalypse in Catholic bibles, because of its similarity to such literature. Our first reading (from Revelations 12:1-6 ) for the Catholic feast of the Assumption includes an adaptation of this mythic scenario to the situation of Christianity under Roman persecution in the 1st century to encourage believers in Jesus and his resurrection – a faith that secures them safety in heaven, but how the rest of us, still living in our world, are still threatened by evil. The story could bring to mind the Assumption of Mary into heaven – waiting with Christ for the rest of us after our struggles against the evil forces in our world. There are ‘secular’ stories of old about such sort of events.

In the Acts 12:1-11 Luke is writing the remarkable account of the expansion of Christianity and the development of the church; and this is despite external opposition, even persecution, and their leaders’ inadequacies and failings. The story is built around the two different characters in the early church of Peter and Paul. Whereas Peter was a headstrong, simple Galilean Jewish fisherman who followed Jesus throughout His public ministry, Paul was a well educated Jew and Roman citizen living outside of the Jewish territory, who after a special encounter with Jesus turned from antagonism to Christians to become an apostle of Christianity to the Gentiles. The phrase “in those days” at the beginning of today’s reading, alludes to the time when the followers of Jesus in Jerusalem and the surrounding area expanded and even included followers of Jesus’ Way who were not Jews – they were Samaritans or even Gentiles. It was this expansion that began to cause disturbances in Jerusalem. Herod, the local ruler, wanted to keep the peace in order to retain favour within the Roman empire, and so began to arrest the Jewish Christian leaders who were the source of the trouble. So our reading concerns the imprisonment of Peter; it was during the feast of unleavened Bread – a sacred time in Jerusalem – so he would be executed after the Passover, as James had been earlier. The story of his escape was passed down by word of mouth and that is what is related here by Luke. This is a good story illustrating how faith can lead us into difficulties and yet God can save us.
