Why did the writing and ideas of Aristotle disturb some medieval Christians?

Some medieval Christians found Aristotle's ideas disturbing because they seemed to conflict with certain Christian teachings and beliefs. For example, Aristotle's emphasis on reason and observation could be seen as placing too much importance on worldly knowledge over divine revelation. Additionally, Aristotle's views on topics such as the immortality of the soul and the nature of the universe differed from Christian doctrine, causing concern among some church scholars.
