Burial facing East. That is the Christian way, expressing our hope in the resurrection.
It wasn't always the Christian way, having never been advocated in Scripture.
There are whole cemetaries of Coptic - Orthodox - Christians from the second to the fifth centuries who were mummmified and placed in elaborate cartonage coffins with a few bits and pieces - There was one next to the dig I was engaged in at Tanis - in fact we had to rebury a few who were buried on top of a foundation deposit, and they did not all face the same direction.
Also, in the Saxon and Celtic traditions which existed till the sixth century throughout Europe - and parts of Norway and Sweden, when they were evangelised - Christian burials were found facing various points of the compass, and evidence which confirms Christian cremations have been found in Byzantium dating to as late as the ninth century.
