Human genes become defective by mutation and by chromosome aberration

The term eugenics means “sell born through the judicious matching of superior genes”• Negative (altering genetic

endowment by removing or correcting harmful genes)

• Positive (creating new beings).

The Bible and Genetic Engineering

The Bible and Genetic Engineering

Bible is a of complete and perfect source of moral and spiritual information (2 Tim. 3:16-17; 2 Pt. 1:3)

Difficult to discover how Bible is to be applied in complex problems of modern society

Must search for the principles that are applicable

Biblical Ethics and Reproduction Technology

Biblical Ethics and Reproduction Technology

Reproductive technologies - techniques that deal with male and female infertility through artificial reproduction

Two distinctive areas in which biblical ethics are relevant to human reproduction technologies: before conception and at conception

Genetic counseling is a medical speciality that uses the latest

information on birth defects and inherited diseases to help people as

they strive to plan their families, protect their health, and protect the

health of their children.

Page 13: Human Engineering Cloning, Stem-Cell Research, and In Vitro Fertilization

♦ Counselors have training in genetics♦ Their goal is to translate up-to-date

genetic knowledge into practical, useful information

♦ To date, scientists have isolated over 3,000 genetic defects among humans

♦ Awareness of these defects may aid those at risk in their decision making

Page 14: Human Engineering Cloning, Stem-Cell Research, and In Vitro Fertilization

Those at risk: People who have a family

history of inherited disease(s) Women who have experienced

two or more miscarriages Workers whose jobs expose

them to a potentially harmful environment

Those married to first cousins or other blood relatives

Etc.

Two choices:• Terminate a pregnancy if the fetus

is found to be defective – this is both unethical and unscriptural

• To have or nor have children – either choice is ethical and scriptural Birth control is permissible

scripturally – and wise, if there is evidence that a child might be diseased or disabled

Reproductive Cloning The word “clone” derives from the

Greek term klon, meaning a “sprout” or “twig.”

Cloning is an asexual process of reproduction that results in an exact genetic duplicate of the original

Thus, it refers to a method of reproduction apart from the parental, sexual-mating process that is characteristic of most organisms.

“Producing people in ‘herds’ in order to harvest spare parts, for use in

laboratory statistical studies like so many guinea pigs, or merely to satisfy personal egos in a vain attempt to guarantee physical

immortality is abhorrent”

(Bert Thompson, Ft. Wroth Lectures, 2000)

Cloning Humans Is Morally Wrong!

• Cloning opposes God’s design for bringing children into the world in a family unit [includes both a husband and wife in the procreation act]

• Marriage is to proceed the bearing of children (1 Tim. 5:14; Gen. 4:1)

• Children are to be reared within the circle of the family unit (Gen. 1:28; 2:24; cf. Eph. 6:1-4)

Dolly’s experimenters used 277 cloned embryos to produce one sheep, meaning 276 failed

In attempt to clone one human, hundreds of embryos will be produced and die in the process – embryos are living human beings (Gen. 9:6; Rom. 13:9)

Therapeutic Cloning

• “Therapeutic” Cloning creates an embryo for destruction

• Therapeutic cloning involves cloning human embryo cells to get stem cells from them (killing the embryo)

• Stem cell - a cell that has the ability to continuously divide and differentiate (develop) into various other kinds of cells/tissues

Page 28: Human Engineering Cloning, Stem-Cell Research, and In Vitro Fertilization

Kinds of Stem Cells

Stem cell type Description Examples

TotipotentEach cell can develop into a new individual

Cells from early (1-3 days) embryos

PluripotentCells can form any (over 200) cell types

Some cells of blastocyst (5 to 14 days)

Multipotent

Cells differentiated, but can form a number of other tissues

Fetal tissue, cord blood, and adult stem cells

• Delivery of genetic therapies

• Delivery chemotherapeutic agents

Adult stem cells (obtained from adult tissues, cord blood, etc.) do not pose any ethical controversies, since they do not destroy complete human beings

However, embryonic stem cells are isolated by destroying human embryos

When the sperm of the husband is used (AIH) the conception of the couples own child results – no biblical principle is violated

The use of donor sperm, donor eggs, or surrogate mothers, stands in stark contradiction to God’s plan for the home

The family unit is the avenue by which children may be brought into the world legitimately (Gen. 4:1)

Parental responsibility begins at conception and continues to a point of independent maturity

In vitro (IVF) is the procedure whereby the woman’s egg [removed by laparoscopy] is fertilized with sperm in a laboratory Petri dish – the so-called “test tube” baby

Multiple eggs are extracted and fertilized, but only a few (appearing to be the healthiest) are selected for implantation – the remaining embryos are destroyed
