...indeed not! There are gradations and levels of sin in Mosaic Law, and convicting a person of a capital crime is extremely difficult.
Committing a homosexual act, or adulatery or bestiality, unless performed in public in front of witnesses, is not likely to result in a conviction. Eating a non-kosher animal is not punishable by death.
Well then, you stick to Mosaic Law, and I'll stick to Christianity...
Mosaic (Levitican) Law is extremely harsh (IMHO) as in (KJV) LEV 20:10 "And the man that commiteth adultery with another man's wife, even he that commiteth adultery with his neighbor's wife, the adulterer and adulteress shall SURELY BE PUT TO DEATH!"...
However, how do you explain that King David who committed adultery with the wife of Uriah and even had Uriah placed in the front ranks in battle so he would be killed was not punished by God; nor was the woman at the well in the New Testament, nor the woman caught in the very act of adultery? Perhaps Moses got the interpretation wrong?
Well if blaspheming the holy spirit is the one transgression that can not be forgiven it seems some are worse than others.
Every sin and blasphemy will be forgiven men, but the blasphemy against the Spirit will not be forgiven (Mt. 12:31)
