Catholic theologian Norman Ford has used contemplation and study to arrive at a moral framework on embryonic stem cells different from that of the bishops. He argues that an early embryo is not a human person. He bases this argument on the knowledge we now have from embryology and a centuries-old Catholic teaching that the soul and personhood is not conferred on the embryo until the 14th day. Ford and others argue that until the 14th day, when a membrane is formed, the collection of cells is not a self-organizing entity. These cells could not become a human being prior to implantation in the uterine wall.
This guy misunderstands Catholic moral theology.
