To the Subcommittee on Health and Environment House Commerce Committee
February 12, 1998
I am Cardinal William Keeler, Archbishop of Baltimore and a member of
the Committee for Pro-Life Activities of the National Conference of
Catholic Bishops. It is on behalf of this Conference that I speak to
you today about the moral challenge presented by human cloning.
The sanctity and dignity of human life is a cornerstone of Catholic
moral reflection and social teaching. We believe a society can be
judged by the respect it shows for human life, especially in its most
vulnerable stages and conditions.
On this basis, the Catholic Church strongly opposes the taking of human
life through abortion, euthanasia or destructive experiments on human
At first glance, human cloning may not seem to belong on this list. It
is presented as a means for creating life, not destroying it. Yet it
shows disrespect toward human life in the very act of generating it.
Cloning completely divorces human reproduction from the context of a
loving union between man and woman, producing children with no "parents"
in the ordinary sense. Here human life does not arise from an act of
love, but is manufactured to predetermined specifications. A developing
human being is treated as an object, not as an individual with his or
her own identity and rights. As one group of scientific and other
experts advising the Holy See has written:
In the cloning process the basic relationships of the human person are
perverted: filiation, consanguinity, kinship, parenthood. A woman can
be the twin sister of her mother, lack a biological father and be the
daughter of her grandmother. In vitro fertilization has already led to the confusion of parentage, but cloning will mean the radical rupture of these bonds.1
Such moral concern transcends denominational bounds and has been
eloquently expressed by some of our country's most respected
philosophers and ethicists. Writes Professor Leon Kass of the
University of Chicago:
Human cloning would... represent a giant step toward turning begetting
into making, procreation into manufacture (literally, something
"handmade")... [W]e here would be taking a major step into making man
himself simply another one of the man-made things.2
From the dehumanizing nature of this technique flow many disturbing
consequences. Because human clones are produced by a means more suited
to more primitive forms of life -- a means which involves no loving
relationship, no personal investment or responsibility for a new life,
but only laboratory technique -- they would be uniquely at risk of being
treated as "second-class" human beings.
The very scenarios often cited as justifications for human cloning are actually symptoms
of the moral problem it creates. It has been said that cloning could
be used to create "copies" of illustrious people, or to replace a
deceased loved one, or even to provide a source of spare tissues or
organs for the person whose genetic material was used for the procedure.
In each proposal we see a utilitarian view of human life, in which a
human being is treated as a means to someone else's ends instead of as a
person with his or her own inherent dignity. This same attitude lies
at the root of human slavery.
Let me be perfectly clear. In reality a cloned human being would not
be, in any sense, an "object" or a substandard human being. Whatever
the circumstances of his or her origin, he or she deserves to be treated
as a human person with an individual identity. But the depersonalized
technique of manufacture known as cloning disregards this dignity and
sets the stage for further exploitation. Cloning is not wrong because
cloned human beings lack human dignity -- it is wrong because they have
human dignity, and deserve to come into the world in ways that respect
this dignity. Each child has a right to be conceived and born as the
fruit of a loving union between husband and wife, to be loved and
accepted as a new and distinct individual.
Ironically, the most startling evidence of the dehumanizing aspects of cloning is found in some proposals ostensibly aimed at preventing
human cloning. The National Bioethics Advisory Commission (NBAC), and
now some members of Congress, favor legislation that would not ban human
cloning at all -- but would simply ban any effort to allow cloned human
beings to survive. In these proposals, researchers are allowed to use
cloning for the unlimited mass production of human embryos for
experimentation -- after which they are required to destroy them,
instead of allowing them to implant in a woman's womb.3
Enactment of such a proposal would mark the first time in history that
the U.S. government defined a class of human beings that it is a crime not
to destroy. These human embryos -- produced without true parents, and
hence without protectors -- would be created at the outset for the sole
purpose of experimentation and destruction.
Human embryo research has been debated in this body before. Three years
ago the National Institutes of Health proposed that federally funded
researchers be allowed to perform nontherapeutic experiments on human
embryos produced by in vitro fertilization -- including embryos
produced solely for research purposes. The moral outcry against this
proposal was almost universal. Opinion polls showed massive opposition,
and the NIH panel making the recommendation was inundated with over
50,000 letters of protest. The Washington Post, while reaffirming its stand in favor of legalized abortion, editorialized against the Panel's recommendation:
The creation of human embryos specifically for research
that will destroy them is unconscionable... [I]t is not necessary to be
against abortion rights, or to believe human life literally begins at
conception, to be deeply alarmed by the notion of scientists' purposely
causing conceptions in a context entirely divorced from even the
potential of reproduction.4
President Clinton ultimately set aside the recommendation allowing
creation of "research embryos," and Congress for the past three years
has voted to prohibit funding of all harmful embryo research -- most
especially the creation of "research embryos."
Why, then, are these moral judgments suddenly reversed if the human
embryo has been produced by cloning? Why is Congress now being urged to
endorse the proposition: "The creation of human embryos by cloning
specifically for research that will destroy them is a national
priority"? It seems the cloning procedure is so demeaning that people
somehow assume that a brief life as an object of research, followed by
destruction, is "good enough" for any human produced by this technique.
The fact that the procedure invites such morally irresponsible policies
is reason enough to oppose it.
The NBAC approach does not even make sense as a barrier to cloning for
reproductive purposes. For a great deal of destructive experimentation
using cloned human embryos would be a necessary step toward the
production of a live-born infant by cloning. We have all learned that
as many as 276 sheep embryos, fetuses and newborn lambs had to die so
that one sheep, "Dolly," could be produced. Scientists can expect
similar results from initial attempts at human cloning -- indicating
that it would be morally irresponsible to make the attempt. Yet
legislation based on the NBAC approach would give the federal
government's blessing to such experiments. Researchers who discard
hundreds or thousands of human embryos in failed cloning attempts could
resort to the defense that such cavalier disposal of human life is
exactly what the federal law requires.
Some will ask: Are we really speaking here of a human embryo, let alone a
human life? By using these terms do we inject religious belief into
this debate? The answer is emphatically no. Even the NIH Human Embryo
Research Panel, which recommended federal funding for destructive human
embryo experiments, called the early human embryo "a developing form of
human life" which "warrants serious moral consideration."5
If some wish to deny membership in the human family to human beings in
the earliest stage of their development, it is they who impose an
ideological filter on the facts.6 To claim that one is banning "human cloning" by simply banning the nurture or live birth of human embryos already produced by cloning is to distort language and common sense.
The Church is also sensitive to claims that cloning is necessary for the
pursuit of valuable medical research. We hold that "medicine is an
eminent, essential form of service to mankind."7 Research
involving the cloning of animals, plants, and even human genes, cells
and tissues can be beneficial to human beings and presents no intrinsic
moral problem. However, when research turns its attention to human
subjects, we must be sure that we do not undermine human dignity in the very process of seeking to serve it.
Human experimentation divorced from moral considerations may well
progress more quickly on a technical level -- but at the loss of our
sense of humanity. The Tuskegee syphilis study, Nazi Germany's
hypothermia experiments, and our own government's Cold War radiation
experiments will always be remembered in the history of modern medicine
-- but not in a positive light. Any "progress" they may have brought on
a technical level is far overshadowed by their mistreatment of human
There has been much speculation in recent months about the ways human
cloning might revolutionize medical research on various diseases. In
all these areas of research, however, alternatives seem to be possible
which do not involve the use of cloning technology to create and destroy
human embryos. For example, some researchers may want to use somatic
cell nuclear transfer to create "customized stem cell lines" genetically
matched for individual patients -- a procedure that in each case would
require creating, developing and then killing a human embryo that is the
patient's identical twin. Yet even the National Bioethics Advisory
Commission described this avenue of research as "a rather expensive and
far-fetched scenario," and reminded us that a moral assessment is
necessary as well:
Because of ethical and moral concerns raised by the use
of embryos for research purposes it would be far more desirable to
explore the direct use of human cells of adult origin to produce
specialized cells or tissues for transplantation into patients.
Surely, anyone who understands the need for ethically responsible
science can agree with this judgment. One great benefit of a ban on
human cloning is that it will direct the scientific enterprise toward
research that benefits human beings without forcing them to
produce, exploit and destroy fellow human beings to gain those benefits. Creating human life solely to cannibalize and destroy it is the most
unconscionable use of human cloning -- not its highest justification.
Thank you for your attention. I would be glad to try to answer any questions.

6While some fertility specialists have used the term
"pre-embryo"to describe the first 14 days of human development, a
scientific expert who strongly supports embryo research recently wrote
that this term was embraced "for reasons that are political, not
scientific." The term "pre-embryo," he writes, "is useful in the
political arena -- where decisions are made about whether to allow early
embryo (now called pre-embryo) experimentation..." Biologically, in the
human species and others, an embryo exists from the one-celled stage
onwards. See Lee Silver, Remaking Eden: Cloning and Beyond in a Brave New World (Avon Books 1997), p. 39.
