PARIS- Hans Kueng, Roman Catholicism's best known rebel theologian, is considering capping a life of challenges to the Vatican with a final act of dissent - assisted suicide.
Kueng, now 85 and suffering from Parkinson's disease, writes in final volume of his memoirs that people have a right to "surrender" their lives to God voluntarily if illness, pain or dementia make further living unbearable.
The Catholic Church rejects assisted suicide, which is allowed in Kueng's native Switzerland as well as Belgium, the Netherlands, Luxembourg and four states in the United States.
"I do not want to live on as a shadow of myself," the Swiss-born priest explained in the book published this week. "I also don't want to be sent off to a nursing home ... If I have to decide myself, please abide by my wish."
Kueng has championed reform of the Catholic Church since its 1962-1965 Second Vatican Council, where he was a young adviser arguing for a decentralized church, married priests and artificial birth control. The Council did not adopt these ideas.
A professor at the German university of Tuebingen since 1960, Kueng was stripped by the Vatican of his license to teach Catholic theology in 1979 after he questioned the doctrine of papal infallibility and ignored Vatican pressure to recant.
The university responded by making him a professor of ecumenical theology, securing him a post from which he wrote dozens of books, some of them best-sellers, and many articles.
