“Since it must be treated from conception as a person, the embryo must be defended in its integrity, cared for, and healed, as far as possible, like any other human being.” (CCC, No. 2274)

“(Human Reproductive) Cloning, like in vitro fertilization, participates in the basic evil of moving human procreation out of the setting of committed marital intimacy and into the laboratory. Human procreation is not meant to occur in that setting, because it is inherently dehumanizing to bring a new human being into the world through means that replace the marital act. Each of us has a right to be brought into the world as the fruit of marital love, rather than as the product of technical domination and manufacturing protocols…

“If human reproductive cloning (i.e., the bringing to birth of a new child who is an identical twin to somebody else) is wrong, then therapeutic cloning is worse—it is the creation of that same identical twin for the premeditated purpose of ending his life to harvest his tissues.”
