The Bible is very clear that sexual relations between humans and animals is a vile, base crime . The fact that Mrs. White describes amalgamation as a base crime is irrefutable evidence she was describing bestiality, not intermarriage between humans with racial or religious differences. A recent defense of Mrs. White's statement has arisen with the advent of genetic engineering. Some have suggested the ancients performed genetic manipulations in the laboratory. This sounds plausible to those who do not understand the difficulties of genetic engineering.
Genetic engineering is a very complex process that science is only now beginning to grasp.
It requires the use of super-computers and highly advanced technology. There is absolutely no evidence that the advanced technology needed to accomplish this ever existed in any society after the flood. None of the Biblical prophets had to go back and alter their writings to remove statements. We are not the first to ask these questions. People have been asking those questions for over 150 years.
