The Archbishop of Westminster Cardinal Vincent Nichols and Archbishop of Canterbury Justin Welby joined leaders of the other main faiths and Christian denominations in Britain to condemn the Assisted Dying Bill.
In a statement ahead of this week's second reading of Lord Falconer's bill in the House of Lords, the faith leaders warned that the bill would have "a serious detrimental effect on the wellbeing of individuals and on the nature and shape of our society."
They said: "Every human life is of intrinsic value and ought to be affirmed and cherished. This is central to our laws and our social relationships; to undermine this in any way would be a grave error."
They said the bill "would allow individuals to participate actively in ending others’ lives, in effect colluding in the judgment that they are of no further value. This is not the way forward for a compassionate and caring society."
