Thank you for your letter.
In the Book of Amos, it is notable that Moab is condemned for burning the bones of the king of Edom. This failure to respect the remains of the dead will cause the Lord to "send a fire upon Moab and it shall devour the palaces…" (2:2).
Cremation of the dead was common practice amongst the ancient Greeks, Romans and Vikings. However, once these nations were converted to Christ they ceased to cremate their dead and began the practise of Christian burial.
