Rt Revd Mike Hill has insisted that it is possible for people to die with dignity "without killing them".
His comments are at odds with the former Archbishop of Canterbury, Lord Carey, who changed his mind on the issue to be a supporter of assisted dying.
Carey, alongside The Bishop of Buckingham, were amongst a group of Christians and Jews that set out an argument in favour of assisted dying in The Daily Telegraph over the weekend.
They wrote: "There is nothing sacred about suffering, nothing holy about agony, and individuals should not be obliged to endure it."
But the opposing Bishop Hill said that: "We need more palliative care provision rather than handing out the right in law to take life.
"The supporters of physician-assisted suicide are very clear that this is a simple matter of individual choice - choice being the great god of a consumerised society.
"Except of course the choice they present us with is extreme."
He added that: "The Church of England - with the exception of a high-profile, now retired, archbishop (and friend) and some of our members and clergy - has been resolutely against a change in the law."
Next month MPs will debate an Assisted Dying Bill, introduced by Rob Marris.
It mirrors proposals suggested by Lord Falconer last year, but adds that people thought to have no more than six months to live, who have a "settled intention" to end their life, could be given a lethal dose of drugs on the agreement of two doctors, as well as a judge.
Last week 68-year-old Bob Cole from Cheshire pleaded with MPs to support the bill, before taking his own life at the Dignitas clinic in Switzerland.
