If it is against the Christian moral code to support IV-embryo transfer, how can moral Christians pray for a procedure that is not morally allowed by their God?
What you have produced is a loaded question. In any case, whether IV transfer is against the Christian moral code or not, Christians also pray for sinners. BTW Christians also serve in combat.
Hmm. This was not a case of praying for sinners, but a case of praying for the sin to be successfull. By praying for success, there will be more people trying IV-embryo transfer than before. But I may be mistaken in my assumption that fundamental Christians consider IV-embryo transfer a sin. Please correct me if I am wrong.
