Why did churches frown upon instruments in the renaissance ages?

During the Renaissance, many churches frowned upon the use of instruments in worship primarily due to their association with secular music and the belief that they could distract from the spiritual message of hymns. Additionally, some church leaders viewed instruments as potentially leading to emotional excess or a lack of reverence in worship. The emphasis was on vocal music, particularly plainchant and polyphony, which was considered more suitable for conveying the sacred texts. Ultimately, the church aimed to maintain a focused and solemn atmosphere in religious settings.
