The Beginning of Human Life
The Bible affirms that God is the Lord and giver of all
life.1 Human beings are uniquely made in God’s
image,2 and each individual human being is infinitely
precious to God and made for an eternal destiny.3 The
Christian attitude toward human life is thus one of
reverence4 from the moment of fertilization to death.
Definition of human life
1. A living human being is a self-directed,5 integrated
organism6 that possesses the genetic endowment of the species
Homo sapiens7 who has the inherent active biological
disposition (active capacity and potency)8 for ordered growth
and development9 in a continuous and seamless maturation
process, with the potential to express secondary characteristics such as
rationality, self-awareness, communication, and relationship with God,
other human beings, and the environment.
2. Thus, a human being, despite the expression of different and more
mature secondary characteristics, has genetic and ontological identity
and continuity throughout all stages of development from fertilization
until death.
3. A human embryo is not a potential human being, but a human being
with potential.
Biological basis for the beginning of human life
1. The life of a human being begins at the moment of fertilization
(fusion of sperm and egg).10 “Conception” is a
term used for the beginning of biological human life and has been
variously defined in the medical and scientific literature as the moment
of fertilization (union or fusion of sperm and egg), syngamy (the last
crossing-over of the maternal and paternal chromosomes at the end of
fertilization), full embryonic gene expression between the fourth and
eighth cellular division,11 implantation, or development of
the primitive streak. Scientifically and biblically, conception is most
appropriately defined as fertilization. The activation of an egg by the
penetration of a sperm12 triggers the transition to active
organismal existence.
2. It is artificial and arbitrary to use other proposed biological
“markers” (such as implantation, development of a primitive
streak, absence of potential for twinning, brain activity, heartbeat,
quickening, viability, or birth and beyond) to define the beginning of
human life.
Biblical basis for the beginning of human life
1. Procreation is acknowledged in the Bible to be the gift of
God.13
2. The mandate for human procreation in Genesis 1:27-28 and 9:1,7
implies that the God-ordained means of filling the earth with human
beings made in His image is the proper reproductive expression of human
sexuality in marriage. Human beings do not merely reproduce “after
their kind”; they beget or procreate beings that, like themselves,
are in the image of God. (see CMDA Statement on Reproductive
Technology)
3. Human beings are created as ensouled bodies or embodied
souls14 (Genesis 2:7). Together the physical and spiritual
aspects of human beings bear the single image of God and constitute the
single essential nature of human life.15 A biological view of
human life beginning at fertilization is therefore consistent with the
Biblical view of human life.
4. From fertilization on, God relates to the unborn in a personal
manner.16 Between fertilization and birth, which are
regularly linked in Biblical language17 God continues His
activity in the unfolding and continuous development of the fetus.
5. The Bible assumes a personal and moral continuity through
fertilization, birth, and maturation.18
6. The Bible, the Church in all its formative Creeds19 and
Ecumenical Councils,20 and the witness of the Holy Spirit
attest to the beginning of the incarnation, wherein the second person of
the Trinity took upon himself human nature, being conceived
(“conceived” is to be understood as
“fertilization;” see The Beginning of Human Life, Addendum
II: Conception and Fertilization: Defining Ethically Relevant Terms) by
the power of the Holy Spirit in the womb of the Virgin
Mary.21 The uniqueness of the event and its mode does not
affect its relevance to the question of the beginning of human life.
From conception the Son of God is incarnate, his human nature made like
us in every way.22 It follows that authentic human existence
begins at conception or fertilization.
The Moral Worth of Human Life
1. The moral worth of a human being is absolute and does not consist
in possessing certain capacities or qualities—e.g.,
self-consciousness, self-awareness, autonomy, rationality, ability to
feel pain or pleasure, level of development, relational
ability—that confer a socially-defined status of
“personhood” (a quality added to being). A human being
consists in the entire natural history of the embodied self. A human
being is a person.
2. The moral worth of a human being at all stages of development
consists not merely in a) the possession of human chromosomes nor b) the
fact that he or she may someday grow and develop into a more mature
human individual. In fact, he or she already is the same individual
being who may gradually develop into a more mature human individual.
Conclusions
1. Every individual from fertilization is known by God, is under His
providential care, is morally accountable, and possesses the very image
of God the creator.
2. Since human life begins at fertilization, the full moral worth
afforded to every human being is equally afforded from fertilization
onward throughout development. Vague notions of “personhood”
or social utility have no place in decisions regarding the worth,
dignity, or rights of any human being.
3. Because all human beings derive their inherent worth and the right
to life from being made in the image of God, standing in relation to God
as their personal Creator, a human being’s value and worth is
constant, whether strong or weak, conscious or unconscious, healthy or
handicapped, socially “useful” or “useless,”
wanted or unwanted.
4. A human beings life may not be sacrificed for the economic or
political welfare or convenience of other individuals or society.
Indeed, society itself is to be judged by its protection of and the
solicitude it shows for the weakest of its members.23
5. Human life, grounded in its divine origin and in the image of God,
is the basis of all other human rights, natural and legal, and the
foundation of civilized society.

5. Early zygote dependence on maternal genetic material does not argue
against this, since the role and integration of this information into
the organism’s development are determined by the organism
itself.
6. The term “organism” is a biological concept that refers
to the functional unity of the organism, specifically the functions of
integration, control, and behavior (and in this case, development) of
the organism as a whole, whether single cellular, multi-cellular,
multi-tissue, or multi-organ. Implicit in this concept is the primacy of
the functional unity of the organism as a whole and not merely the sum
of the function of its parts. This definition is also univocal and can
be applied to all forms of living organisms.
7. Genetic identity with the species Homo sapiens alone is a necessary,
but not sufficient, criteria for defining a human being.
8. Both human genetic identity and active potential and capacity (an
inherent disposition for development) define a unique human being. While
somatic cells have genetic identity to human beings (they have a latent
potency and capacity such as exists in all raw materials), they do not
possess an inherent active biological disposition (active potency and
capacity) for further development into a unique human being. Somatic
cell nuclear transfer (cloning) artificially confers such an active
potency and capacity on a cell with genetic identity resulting in a
unique human being.
9. Hydatiform moles (the result of abnormal fusions between egg and
sperm) and teratomas (arising from the abnormal parthenogenic division
of germ cells) lack ordered growth and development.
10. Some scientists and theologians note that it is only at the end of
the process of fertilization (the joining of the male and female
chromosomes at syngamy) that a substantive change has taken place
resulting in a new, unique, living, individual human person. According
to this view, the substantive change inherent in the human diploid
single-cell zygote is not yet present at the moment of fertilization
(union or fusion of sperm and egg) or during the pronuclear stage of
fertilization. However, these cells do contain within themselves the
organizing principle for the self-development and self-maintenance of
the full human organism.

15. Some Christians hold that Scripture describes human beings as
composed of distinct parts, either body and soul (dichotomy), or body,
soul, and spirit (trichotomy). CMDA is aware of this viewpoint but feels
that the issue in clinical medicine should be approached viewing a human
being as a functional unity. The body soul distinction could provide a
rationale to those who would disrespect human life is the
“higher” (implying soul) functions of
“personhood” or “rationality” are not
present.
