I want to know the answer to the following question:
Why were instruments more unwelcome to Christians?
All the background I'm provided with is that "They were considered a Catholic innovation, not widely practiced until the 18th century, and were opposed vigorously in worship by a number of Protestant Reformers, including Martin Luther (1483–1546), Ulrich Zwingli, John Calvin (1509–1564) and John Wesley (1703–1791).". Is that enough to answer the question?
Answer: yes
