Christology centres on the figure of Christ as the union of two natures God and man in one person. Orthodox theology can be summed up in Athanasius's statement, 'God became man in order that man might become God'. For the Orthodox, man is justified by faith and works according to grace. There is no such thing as original sin, only fallen man in his sins, who is rescued not only from sin but also from decay and corruption. The Orthodox are said to be obsessed with eschatology .
Millenarianism certainly plays a large part, for example, in Russian spirituality.
The living pray for the dead, including the saints, as well as for and with sinners awaiting judgement. This is because Orthodox worship is designed to represent heaven come down to Earth. The believer prays surrounded by angels and the communion of saints. EMJ Further reading Kallistos Ware, The Orthodox Way . Jackson, E M, Dr. EMJ Bloomsbury Guide to Human Thought 2.
