No one can fail to see the dramatic and distressing consequences of this
pragmatism that conceives of truth and justice as malleable qualities
that human beings themselves can shape. One relevant example among
others is man's attempt to control the sources of life through
experiments in human cloning. Here, we can see for ourselves the theme
the Meeting [for Friendship Among Peoples] refers to: the violence with
which people seek to appropriate the true and the just, reducing them to
values which can arbitrarily be disposed of without recognizing any
kind of limit, apart from those fixed and continuously surpassed by
their technological operability.
...Christ taught another way: it is that of respect for human beings;
the priority of every method of research must be to know the truth about
human beings, in order to serve them and not to manipulate them
according to a project sometimes arrogantly seen as better even than the
plan of the Creator.
Pope John Paul II, Message for the 25th Meeting for Friendship Among Peoples (August 2004), nos. 2, 3
I am speaking of a tragic spiral of death which includes murder,
suicide, abortion, euthanasia.... To this list we must add irresponsible
practices of genetic engineering, such as the cloning and use of human
embryos for research, which are justified by an illegitimate appeal to
freedom, to cultural progress, to the advancement of mankind. When the
weakest and most vulnerable members of society are subjected to such
atrocities, the very idea of the human family, built on the value of the
person, on trust, respect and mutual support, is dangerously eroded. A
civilization based on love and peace must oppose these experiments,
which are unworthy of man.
Pope John Paul II, Message for the Celebration of the World Day of Peace (2001), no. 19
In any event, methods that fail to respect the dignity and value of the
person must always be avoided. I am thinking in particular of attempts
at human cloning with a view to obtaining organs for transplants: these
techniques, insofar as they involve the manipulation and destruction of
human embryos, are not morally acceptable, even when their proposed goal
is good in itself. Science itself points to other forms of therapeutic intervention
which would not involve cloning or the use of embryonic cells, but
rather would make use of stem cells taken from adults. This is the
direction that research must follow if it wishes to respect the dignity
of each and every human being, even at the embryonic stage.
Pope John Paul II, Address to the 18th International Congress of the Transplantation Society (2000), no. 8
[T]he distinction that is sometimes drawn between reproductive and
therapeutic cloning seems specious. Both involve the same technical
cloning process and differ only in goal. Both forms of cloning involve
disrespect for the dignity of the human being. In fact, from an ethical
and anthropological standpoint, so-called therapeutic cloning, creating
human embryos with the intention of destroying them, even if undertaken
with the goal of possibly helping sick patients in the future, seems
very clearly incompatible with respect for the dignity of the human
being, making one human life nothing more than the instrument of
another. Further, given the fact that cloned embryos would be
indistinguishable from embryos created by in vitro fertilization and
could readily be implanted into wombs and brought to birth, we believe
it would be practically impossible to enforce an instrument that allowed
one type of cloning while banning the other.
Archbihop Celestino Migliore to the United Nations on the International Convention Against the Cloning of Human Beings (October 21, 2004)
Mr. Chairman, the science may be complex, but the issue for us is simple
and straightforward. The matter of human cloning that involves the
creation of human embryos is the story of the beginning of human
life.... If reproductive cloning of human beings contravenes the law of
nature – a principle with which all delegations appear to agree – so
does the cloning of the same human embryo that is slated for research
purposes. A cloned embryo, which is not destined for implantation into a
womb but is created for the sole purpose of extraction of stem cells
and other materials, is destined for pre-programmed destruction...
If the United Nations were to ban reproductive cloning without banning
cloning for research, this would, for the first time, involve this body
in legitimizing something extraordinary: the creation of human beings
for the express purpose of destroying them. If human rights are to mean
anything, at any time, anywhere in the world, then surely no one can
have the right to do such a thing. Human rights flow from the
recognition that human beings have an intrinsic dignity that is based on
the fact that they are human. Human embryos are human, even if they
are cloned. If the rest of us are to have the rights that flow from the
recognition of this dignity, then we must act to ban cloning in all its
Archbishop Celestino Migliore to the United Nations on the International Convention Against the Cloning of Human Beings (2003)
The Holy See looks upon the distinction between "reproductive" and
so-called "therapeutic" (or "experimental") cloning to be unacceptable.
This distinction masks the reality of the creation of a human being for
the purpose of destroying him or her to produce embryonic stem cell
lines or to conduct other experimentation. Human embryonic cloning must
be prohibited in all cases regardless of the aims that are pursued.
The Holy See supports research on stem cells of post-natal origin since
this approach - as has been demonstrated by the most recent scientific
studies - is a sound, promising, and ethical way to achieve tissue
transplantation and cell therapy that could benefit humanity....
Cloning a human embryo, while intentionally planning its demise, would
institutionalize the deliberate, systemic destruction of nascent human
life in the name of unknown "good" of potential therapy or scientific
discovery.... Since embryonic cloning generates a new human life geared
not for a future of human flourishing but for a future destined to
servitude and certain destruction, it is a process that cannot be
justified on the grounds that it may be able to assist other human
by the Holy See Delegation to the United Nations, at the Special
Committee of the 57th General Assembly on Human Embryonic Cloning (2002)
The act of cloning is a predetermined act which forces the image and
likeness of the donor and is actually a form of imposing dominion over
another human being which denies the human dignity of the child and
makes him or her a slave to the will of others. The child would be seen
as an object and a product of one's fancy rather than as a unique human
being, equal in dignity to those who "created" him or her. The
practice of cloning would usurp the role of creator and would thus be
seen as an offence before God....
There remains, however the fact that reproductive cloning is only part
of the overall issue. Therapeutic cloning, the production of human
embryos as suppliers of specialized stem cells, embryos to be used in
the treatment of certain illnesses and then destroyed, must be addressed
and prohibited. This exploitation of human beings, sought by certain
scientific and industrial circles, and pushed forward by underlying
economic interests, retains all its ethical repugnance as an even more
serious offence against human dignity and the right to life, since it
involves human beings (embryos) who are created in order to be
Archbishop Renato Martino to the United Nations, on an International Convention Against the Reproductive Cloning of Human Beings (2001)
Since 1988, two great global divides have grown deeper: the first is the
ever more tragic phenomenon of poverty and social discrimination ...,
and the other, more recent and less widely condemned, concerns the
unborn child ... as the subject of experimentation and technological
intervention (through techniques of artificial procreation, the use of
"superfluous embryos," so-called therapeutic cloning, etc.). Here there
is a risk of a new form of racism, for the development of these
techniques could lead to the creation of a "sub-category of human
beings," destined basically for the convenience of certain others. This
would be a new and terrible form of slavery. Regrettably, it cannot be
denied that the temptation of eugenics is still latent, especially if
powerful commercial interests exploit it. Governments and the
scientific community must be very vigilant in this domain.
Pontifical Council for Justice and Peace, Contribution to the World Conference Against Racism held in Durban, South Africa (2001), no. 21
In the cloning process the basic relationships of the human person are
perverted: filiation, consanguinity, kinship, parenthood.... In vitro
fertilization has already led to the confusion of parentage, but cloning
will mean the radical rupture of these bonds....
The "human cloning" project represents the terrible aberration to which
value-free science is driven and is a sign of the profound malaise of
our civilization, which looks to science, technology and the "quality of
life" as surrogates for the meaning of life and its salvation....
Halting the human cloning project is a moral duty which must also be translated into cultural, social and legislative terms.
Pontifical Academy for Life, "Reflections on Cloning" (1997), no. 3
[A]ttempts or hypotheses for obtaining a human being without any
connection with sexuality through "twin fission," cloning or
parthenogenesis are to be considered contrary to the moral law, since
they are in opposition to the dignity both of human procreation and of
the conjugal union.

U.S. Bishops' Statements
Revising the name given to the killing reduces its perceived gravity.
This is the ecology of law, moral reasoning and language in action.
Bad law and defective moral reasoning produce the evasive language to
justify evil.... The same sanitized marketing is now deployed on behalf
of...fetal experimentation and human cloning. Each reduces the human
person to a problem or an object.
United States Conference of Catholic Bishops, "Living the Gospel of Life: A Challenge to American Catholics" (1998), II, 11
Human cloning does not treat any disease but turns human reproduction
into a manufacturing process, by which human beings are mass-produced to
preset specifications. The cloning procedure is so dehumanizing that
some scientists want to treat the resulting human beings as subhuman,
creating them solely so they can destroy them for their cells and
While cloning may never produce any clinical benefit, its attack on human dignity has already begun.
