Why Western European culture in the Middle Ages was Christian?

Western European culture in the Middle Ages was called Christian culture for the following reasons: First, Christianity was the main religious belief in Western Europe in the Middle Ages, which deeply penetrated into all aspects of society and had a great influence on people's values, morality and codes of conduct. Christian doctrine emphasizes the importance of individual soul, faith and obedience to God, and respect for church and doctrine. Secondly, the political and social systems in medieval Western Europe were also influenced by Christianity. The church plays an important role in political and social affairs, and the authority of the Pope and the church has great influence on political decision-making and social order. At the same time, monasteries and churches are the centers of society. They not only provide places for religious ceremonies and activities, but also play the roles of education, charity and cultural inheritance. Finally, the art, architecture, literature and philosophy of western Europe in the Middle Ages also showed obvious Christian characteristics. Religious themes have become the theme of works of art, and the architectural styles of churches and monasteries reflect Christian values. Literary works often involve religious themes and symbols, and philosophical thoughts are often intertwined with religious beliefs.
