In my opinion you are wrong, and making an assumed judgment. As a Christian I know that when myself and my loved ones die we we instantly be in God’s loving arms. This is my Faith of Salvation through Jesus Christ. For a Christian there is no “right way” of man made funeral practices. God will be with His people comforting and strengthening us in our grief, and at the same time filling us with His joy. He is the only one who knows what’s in our heart.
