In all countries of Western Europe who adopted Christianity, worship was conducted in Latin. Think about the consequences of this phenomenon.
Since Christianity came to Europe from the Roman Empire, church books were written in Latin, which were unfamiliar to the inhabitants of Western Europe. Despite the adoption of Christianity, the Europeans continued to communicate in their native languages, but they did not know Latin. This led to the fact that the meaning of the teaching remained incomprehensible to them, especially to the common people: people did not understand what they were told about at church services, how they needed to live and what the new faith required of them. In turn, the clergy were given the opportunity to interpret the Gospel at their own discretion.
