That is a very modernist approach. The Orthodox Church is DEEPLY conservative. As the old joke goes, a liberal Orthodox priest is one who may occasionally shave. This is a church that has seen full blown schisms over calendars! The Greek Church is not going to approve cremation. And thank God for it!
Well, if it suits you, that is good.
I DO think that how we live is FAR more important to our good Lord than this death ceremony.
We are not members of a culture or country, such as Greece or Italy, we are ALL members of His Body, wherever we live.
Just an opinion, NRx, just an opinion.
