But on the way back to Nazareth, Joseph said privately to Jesus, ‘What were you thinking of, to upset your mother like that? You know how tender-hearted she is. She was worried sick about you.’

‘And you, Father, were you worried?’

‘I was worried for her, and I was worried for you.’

‘You didn’t need to worry for me. I was safe enough.’

Joseph said no more.

Time went past, and the two boys grew to manhood. Jesus learned the trade of carpentry, and Christ spent all his time in the synagogue, reading the scriptures and discussing their meanings with the teachers. Jesus took no notice of Christ, but for his part, Christ was always forbearing, and keen to display a friendly interest in his brother’s work.

‘We need carpenters,’ he would say earnestly. ‘It’s a fine trade. Jesus is coming on very well. He will be able to marry one day soon, I’m sure. He deserves a good wife and a home.’

By this time the man John, the son of Zacharias and Elizabeth, had begun a campaign of preaching in the country around the Jordan, impressing the people with his teaching about the need for repentance and with his promise of the forgiveness of sins. There were many wandering preachers in Galilee and the surrounding districts at that time; some were good men, some were wicked charlatans, and some were simply mad. John was unusual in his simplicity and directness. He had spent some time in the wilderness, and dressed roughly and ate little. He invented the rite of baptism to symbolise the washing-away of sin, and many came to listen to him and to be baptised.

Among the people who came to listen to him were some Sadducees and Pharisees. These were two rival groups among the Jewish teachers. They disagreed with one another about many matters of doctrine, but each was important and influential.

John, however, treated them with scorn.

‘You brood of vipers! Running away from the anger to come, are you? You’d do better to start doing some good in the world, better to start bearing some fruit. The axe is already lying at the root of the trees. Watch out, because it will cut down every tree that doesn’t bear good fruit, and they will be thrown on the fire.’

‘But what should we do to be good?’ people asked him.

‘If you have two coats, give one to someone who has none. If you have more food than you need, share it with someone who is hungry.’

Even some tax-collectors came for baptism. Tax-collectors were hated by the people, because everyone resented paying money to the occupying forces of Rome. But John didn’t turn them away.

‘What must we do, teacher?’ said the tax-collectors.

‘Take in exactly as much tax as you should, and not a penny more.’

Some soldiers came to him too.

‘Will you baptise us? Tell us what we must do to be good!’

‘Be content with your regular wages, and don’t extort money from anyone with threats or false accusations.’

John became famous in the countryside for the vigour of his words as well as for the ceremony of baptism. He had recently said something that was widely spoken about:

‘I baptise you with water, but there’s someone else coming who is much more powerful than I am. I’m not worthy to untie his sandals for him. He will baptise you with the Holy Spirit and with fire. He’s going to sort the wheat from the chaff; he’s got his winnowing-fork in his hand already; the grain will be safe in the granary, but the chaff will burn with a fire that never goes out.’

Word of his teaching came to Nazareth, and Jesus was curious to go and listen to him. He set off for the Jordan, where he heard that John was preaching. Christ went as well, but the two brothers travelled separately. When they reached the river bank they joined the crowd waiting to be immersed in the water, and watched as the people went down one by one to join the Baptist where he stood waist-deep, wearing the rough camel-hair cloak that was his only garment.

When it was Jesus’s turn, John held up his hand in refusal.

‘It should be you who baptise me,’ he said.

Christ, watching from the bank as he waited for his turn, heard his words with astonishment.

‘No,’ replied Jesus, ‘I’ve come to you. Just do it in the proper way.’

So John held him, and plunged him under the water and lifted him up again.

At that moment Christ saw a dove fly above them and settle in a tree. It might have been an omen. Christ wondered what it might mean, and imagined what a voice might say if it spoke from heaven and told him.

After the baptism Jesus and Christ listened to the preaching of John, and it made a great impression on them both. In fact, Jesus was so impressed by the personality and the words of the Baptist that he decided to give up his trade of carpentry and go into the wilderness as John had done, and see if he too could hear the words of God. So he went off on his own into the desert, wandering from place to place, eating little and sleeping on the rough ground.

Meanwhile Christ went home to Nazareth, and told Mary about the baptism, and told her about the dove, too.

‘It flew right over my head, Mother. And I thought I heard a voice speaking from heaven. It was the voice of God, and it was speaking to me – I’m sure of it.’

‘Of course it was, darling! It was your special baptism.’

‘Do you think I should go and tell Jesus?’

‘If you want to, dear. If you think he’ll listen.’

So he set off, and forty days after Jesus had gone into the wilderness, Christ found him kneeling in a dry river bed and praying. He watched and waited, thinking of what to say, and when Jesus stopped and lay down in the shade of a rock, Christ came and spoke to him.

‘Jesus, have you heard the word of God yet?’

‘Why do you want to know?’

‘Because something happened when you were being baptised. I saw the heavens open above you, and a dove come down and hovered above your head, and a voice said, “This is my beloved son”.’

Jesus said nothing. Christ said:

‘Don’t you believe me?’

‘No. Of course not.’

‘It’s plain that God has chosen you for something special. Look what the Baptist himself said to you.’

‘He was mistaken.’

‘No, I’m sure he wasn’t. You’re popular, people like you, they listen to what you say. You’re a good man. You’re passionate and impulsive, and those are fine qualities, of course they are, as long as they’re regulated by custom and authority. You could have a lot of influence. It would be a shame not to use it for good. The Baptist would agree with me, I know.’

‘Go away.’

‘I know what it is, you’re tired and hungry after all this time in the desert. If you’re the son of God, as I heard the voice say, you could command these stones to become loaves of bread, and they’d have to, and then you could eat as much as you wanted.’

‘Oh, you think so? I know the scriptures, you scoundrel. “Man does not live by bread alone, but by every word that comes from the mouth of God.” Had you forgotten that? Or did you think I had?’

‘Of course I don’t think you’ve forgotten your lessons,’ said Christ. ‘You were as clever as anyone in the class. But consider what good you could do if you could feed the hungry! If they ask for food, you could give them a stone and it would become bread! Think of the starving, think of the misery of famine, think of the bitterness of poverty and the dread of a poor harvest! And you need food just as the poor do. If you’re to do the work that God obviously wants you to do, you can’t do it hungry.’

‘It didn’t occur to you to bring me a loaf yourself, I notice. That would have been more use than a sermon.’
