Roman catholic church
They believed it isn’t just accepted but Aristotle is equal to church. If you don’t accept Aristotle, you are a Heretic because you aren’t believing in the church. It was very easy to not accept Aristotle because more and more people were discovering more and more thing about the earth. No one was going against the church and stating their own beliefs. Their philosophy was: Accept the authority. The church had ALL the authority and it was the church. Their appeal to authority back then is kinda the same now.
