The head of the Russian Orthodox Church says the data-gathering capacity of devices such as smartphones risks bringing humanity closer to the arrival of the Antichrist.

In an interview shown Monday on state TV, Patriarch Kirill said the church does not oppose technological progress but is concerned that "someone can know exactly where you are, know exactly what you are interested in, know exactly what you are afraid of" and that such information could be used for centralized control of the world.

"Control from one point is a foreshadowing of the coming of Antichrist, if we talk about the Christian view. Antichrist is the person who will be at the head of the world wide web that controls the entire human race," he said.
