The largest religious force in Massachusetts, the Roman Catholic Church, has come out squarely against the referendum, as have other prominent faith voices. A handful of smaller denominations support the measure known as Question 2.

But some umbrella faith organ­izations remain loath to stake out a position, reflecting, they say, the range of opinion among their membership on an issue that proponents refer to as “death with dignity” and opponents call “doctor-assisted suicide.”

“It points to the diversity of political and ethical positions within the life of the church right now,” said the Rev. Laura Everett, executive director of the Massachusetts Council of Churches, an ecumenical partnership of 17 Protestant and ­Orthodox denominations, referring to the lack of consensus within the council’s membership. “With complex theological issues that have public policy expression, there are Christians of strong conscience and faith who disagree.”

Rarely does the political system confront matters of life and death so directly. With Election Day less than two months away, many religious leaders are inten­sifying their focus on the question.

The Catholic church is waging an all-out battle against what it calls a “grotesque threat to the elderly and sick.” The church teaches that human life is sacred from conception to natural death,and that suicide in any form is a grave sin.

“We are called to comfort the sick, not to help them take their own lives,” Cardinal Sean P. O’Malley said in a video homily played in churches across the archdiocese this year.

The church is educating ­parishioners about what it sees as flaws in the proposal through brochures, workshops, pew cards, and even a town hall meeting on Catholic TV. It has also been reaching out to other faiths to discuss the issue.

Campaign finance reports released Monday show that Catholic and conservative Christian organizations from outside the state have contributed most of the $900,000 raised by the main committee against the question, the Committee Against Physician Assisted Suicide.

Dignity 2012, the committee in favor of the question, has raised about $310,000, from a combination of out-of-state supporters and groups and ­individual Massachusetts ­donors.

In the broadest terms, the teachings of most forms of Christianity, Judaism, and ­Islam oppose ending life before natural death.

Eight prominent Reform rabbis began circulating a letter to their colleagues Monday argu­ing in a gentle tone against the ballot question, which would allow a coherent patient who is expected to survive six months or less to ask a physician for life-ending medication.

“Although Reform Judaism gives personal autonomy great weight, Judaism has always under­stood that life is a gift and that ultimately life belongs to God,” the letter says.

Opposition is not uniform. A few denominations, like the Unitarian Universalist Association of Congregations, with about 22,000 members in Massachusetts, officially support the concept. The Unitarians and other mainline Protestant denominations typically do not take positions on specific state proposals.

And, in an age when many ecclesiastical hierarchies are weakening, in a country where many people are used to filtering religious beliefs through personal and secular lenses, ­individual clergy and congregants do not necessarily follow the lead of church officials.

The national Episcopal Church, for example, officially opposes physician-assisted suicide. But the Rev. Daphne B. Noyes, a deacon at the Church of the Advent in Boston and a hospital chaplain, said her work with dying people and their families has led her to ­believe the option should be available under rigorously limited circumstances that ensure that participation by all parties is voluntary and deliberate.

“Looking at the ethical principles, this is one of autonomy and justice,” she said.

The Jewish Community ­Relations Council is also declining to take sides. Instead, said executive director Jeremy ­Burton, the group is focusing on raising awareness about the question, which is a challenge in a presidential election year when there are also Senate and congressional races competing for voters’ attention.
