Sagot :
Answer:
a. Lending money and charging interest went against a teaching of the Catholic Church and was seen as sinful.
Explanation:
Lending money at an interest was forbidden by the Catholic Church for Catholic believers, and similar restrictions applied for members of the Eastern Orthodox Church. These prohibitions were based on some Bible scriptures, and on the works of several clergy philosophers, including Italian clergyman Thomas Aquinas, perhaps the most important philosopher of the Middle Ages.
Jewish People, as people outside the Catholic Church, were allowed to charge interest, and for this reason, they took that economic activity and provided the banking service for people across Europe. However, for this same reason, they were looked down on as sinners, or simply as people who did not belong because they did not share the same Christian faith. This is why they were forced to live in ghettos, and were often expelled from their properties, and subjected to all kinds of social persecution.
