Is this the beginning of the Holy Russian Empire? Or Russia aping the Muslim practice of joining Islam with the state?
It is Muslims who are imitating and distorting Christian practices (Islam is much younger religion) like Ramadan and Great Lent (with eating a lot of food after sunset), women covering heads (adding covering of face) etc ...
Christian civilization began when Roman state abandoned pagan gods and embraced Christian religion. Even today many Western states have established state church - like England for example.
The Separation of Church and state is a DISTORTED Christian idea - of the Two Kingdoms - of God and of Caesar. When The Church is completely separated from Western states/governments OTHER religions will take her place. Maybe Militant Secularism or Islam.
