married love with the responsible transmission of life, the
moral character of one's behaviour does not depend only on
the good intention and the evaluation of the motives: the
objective criteria must be used, criteria drawn from the nature
of the human person and human acts, criteria which respect
the total meaning of mutual self-giving and human procreation
in the context of true love".

(27) The obligation to avoid disproportionate
risks involves an authentic respect for human beings and the
uprightness of therapeutic intentions. It implies that the
doctor "above all ... must carefully evaluate the possible
negative consequences which the necessary use of a particular
exploratory technique may have upon the unborn child and avoid
recourse to diagnostic procedures which do not offer sufficient
guarantees of their honest purpose and substantial harmlessness.
And if, as often happens in human choices, a degree of risk
must be undertaken, he will take care to assure that it is
justified by a truly urgent need for the diagnosis and by
the importance of the results that can be achieved by it for
the benefit of the unborn child himself" (POPE JOHN PAUL
II, Discourse to Participants in the Pro-Life Movement
Congress, 3 December 1982: Insegnantenti di Giovanni
Paolo II, V, 3 [1982] 1512). This clarification concerning
"proportionate risk" is also to be kept in mind
in the following sections of the present Instruction, whenever
this term appears.

(29) Cf. POPE JOHN PAUL II, Address to
a Meeting of the Pontifical Academy of Sciences, 23 October
1982: AAS 75 (1983) 37: "I condemn, in the most explicit
and formal way, experimental manipulations of the human embryo,
since the human being, from conception to death, cannot be
exploited for any purpose whatsoever".

of the Family, 4b: L'Osservatore Romano, 25 November
1983.
(31) Cf. POPE JOHN PAUL II, Address to
the Participants in the Convention of the Pro-Life Movement,
3 December 1982: Insegnamenti di Giovanni Paolo II,
V, 3 (1982) 1511: "Any form of experimentation on the
foetus that may damage its integrity or worsen its condition
is unacceptable, except in the case of a final effort to save
it from death". SACRED CONGREGATION FOR THE DOCTRINE
OF THE FAITH, Declaration on Euthanasia, 4: AAS 72
(1980) 550: "In the absence of other sufficient remedies,
it is permitted, with the patient's consent, to have recourse
to the means provided by the most advanced medical techniques,
even if these means are still at the experimental stage and
are not without a certain risk".
(32) No one, before coming into existence,
can claim a subjective right to begin to exist; nevertheless,
it is legitimate to affirm the right of the child to have
a fully human origin through conception in conformity with
the personal nature of the human being. Life is a gift that
must be bestowed in a manner worthy both of the subject receiving
it and of the subjects transmitting it. This statement is
to be borne in mind also for what will be explained concerning
artificial human procreation.

Medical Association, 29 October 1983: AAS 76 (1984) 391.

Doctors, 29 September 1949: AAS 41 (1949) 559. According
to the plan of the Creator, "A man leaves his father
and his mother and cleaves to his wife, and they become one
flesh" (Gen 2:24). The unity of marriage, bound
to the order of creation, is a truth accessible to natural
reason. The Church's Tradition and Magisterium frequently
make reference to the Book of Genesis, both directly and through
the passages of the New Testament that refer to it: Mt
19: 4-6; Mk: 10:5-8; Eph 5: 31. Cf. ATHENAGORAS,

"It would be erroneous ... to think that the possibility
of resorting to this means (artificial fertilization) might
render valid a marriage between persons unable to contract
it because of the impedimentum impotentiae".
