Which entity dominated ideologically the medieval society?

And as we know, the Middle Ages in Europe were also known as the 'Dark Ages', because of the lack of scientific enlightenment. During the Middle Ages, the church dominated society because of their relentless faith in the afterlife, which left no place for reason.

European society was based on religious faith, not on scientific reason.
