When Justin Welby was appointed as Archbishop of Canterbury there were two things we quickly learned about him. The first was that he has a business head on him and used to work in the oil industry - that's significant for a country grappling with issues of financial morality.

Addiction to alcohol costs the UK around £22 billion per annum in health, welfare, social care and prison costs. The expectation is that more than 200,000 people will die prematurely in this country of alcohol related liver disease in the next 20 years. Is addiction a disease or does it signify an absence of will power? Alcoholics Anonymous famously claims that the cycle of addiction can only be broken by surrendering to a higher power. So is a spiritual approach to the problem effective?

Joining Ernie to discuss the spiritual dimension to alcohol addiction and its treatment are Mike Williams, General Director of Stauros Foundation, a Christian Charity which offers fellowship to people suffering or recovering from addiction; Maia Szalavitz a neuro-science journalist with Time.com; and Dr Wendy Dossett Senior Lecturer in Religious Studies at Chester University who has just completed a Research Project on Spirituality and Addiction.

Restorative Justice schemes are increasingly playing a role within the Criminal Justice System. They are designed to confront the criminal with the consequences of his or her actions. Sometimes they involve a meeting between the victim and the offenders, where victims can give their perspective on what has happened and offenders can seek forgiveness.

Many religious groups believe that Restorative Justice principles resonate with their traditions.

Joining Ernie to discuss Restorative Justice are Pavan Dhilowal, Head of Public Affairs at the British Humanist Society and former policy head at a think tank specialising in criminal justice; Khola Hassan, Media Representative at the Islamic Sharia Council; and Tim Newell former Governor of Grendon, a therapeutic prison.

The revelation that horse meat has found its way into supermarket products, and that Muslim prisoners have been fed meals containing pork has highlighted again the way food is produced and animals treated.

Joining Ernie Rea to discuss the place of animals in the religions of East and West are Shimon Cohen, Director of Shechita UK, an organisation which defends the Jewish method of slaughtering animals for food; Barbara Gardner, a trustee of the RSPCA and author of The Compassionate Animal; and Shaunaka Rishi Das a Vaisnav priest from the Oxford Centre of Hindu Studies.

As the bill to allow same sex marriage makes its way through Parliament, Ernie Rea and guests discuss whether homosexuality is compatible with Islam. The Muslim Council of Britain has voiced its opposition, but what does the Koran say about homosexuality - is the prohibition unequivocal and absolute?

To most people the word Rastafarian conjures up images of dreadlocks, the smoking of ganja, and Bob Marley. But Rastafari, as it's more correctly known, is a movement with a complex belief system. It has its origins in Jamaican society in the early 20th century, when black people rose up in protest at oppressive systems imposed by white rulers. But is it just a passing phenomenon? Has it continuing relevance in a fairer, more open society? How does it need to evolve?

"No-one expects the Spanish Inquisition!" The brilliant Monty Python sketch was able to use an historical reference because the very mention of the Inquisition conjured up images of dark dungeons; cruel monks wielding instruments of torture and consigning thousands of alleged heretics to the flames. The Inquisition has had a bad press. But in fact there were several Inquisitions, some more cruel than others. And it is still active. Nowadays it goes under the name of the Congregation for the Doctrine of the Faith and in the 1990s it was run by Cardinal Joseph Ratzinger. So what does it do? How does its present structure relate to its medieval origins? Does it deserve its sinister reputation?

Joining Ernie to discuss the Inquisition are Dr Gemma Simmons, Lecturer in Pastoral and Social Studies at Heythrop College London and a member of the Congregation of Jesus; Dr Christopher Black, Honorary Professor of Italian History at the School of Humanities, at the University of Glasgow; and Cullen Murphy, Editor at Large of Vanity Fair and author of God's Jury, The Inquisition and the Making of the Modern World.

The history of Islam in Mali is a long one. The faith, brought by traders, was adopted slowly over the centuries until the French colonisers arrived, after which its spread was accelerated. The recent conflict in Mali has been portrayed as a struggle between a home-grown "tolerant" Islam and an aggressive Wahabi influence from outside. How accurate is this picture? Ernie Rea is joined by journalist Celeste Hicks, academic Marie Rodet and the South African Sheik and academic Michael Mumisa.

Ernie Rea and guests discuss the reasons behind rising anti-semitism in Europe. A survey published last year revealed that 24% of the French population holds anti semitic views. The figure for Hungary is 63%. In Spain 72% of the people are willing to admit that they are anti Jew. Just 70 years after Hitler tried to wipe out European Jewry, attacks on Jews are on the increase. What is the cause of this resurgence? What can be done to stop it?

It may surprise you to know that the world's tallest hotel is in Makkah. The Clock Tower which is part of the same complex is the world's largest clock tower. None of this would be all that important were it not for the fact that these building are metres away from the Grand Mosque which, for Muslims, is the world's holiest place. In order to create the space for this expansion, large residential districts have been demolished and the residents evicted; many examples of traditional urban architecture have been destroyed. What is behind this programme? Is it cultural vandalism? Or rampant capitalism? Or does it reflect a legitimate theological concern on the part of the Saudi authorities to prevent idolatry? Joining Ernie Rea to discuss the potential destruction of some of Islam's Holy Sites are Yaqub Zaki, Visiting Professor at the Aga Khan Foundation at Harvard University; Mona Siddiqui, Professor of Islamic and Religious Studies at the University of Glasgow; and Irfan Al Alawi, Executive Director of the Islamic Heritage Research Foundation.
