Answer: What difference does it make whether an embryo develops in a test tube or in his mother’s womb? It is merely corporeal development.
The main point is to have a corporeal body from which the soul can develop.
It is possible to develop a new body from one human cell, but the soul will appear in it only when a person himself works on the development of his soul.
