The Dominican friar Johannes Nider (1380–1438), known today as the father of witchcraft literature, played an important role at the Council of Basel (1431–49) on the Council's delegation to the Hussites and its deputation on religious reform. Despite Nider's reputation as a reformer of religious communities, his approach to communal liturgy has not attracted close attention. This article focuses on his broad theoretical treatise, De reformatione religiosorum or De reformatione status cenobitici (On the Reform of the Religious State), in which Nider articulates a philosophical concept of reform as the restoration of beauty, manifested in well-ordered and balanced proportion. In the interest of universal applicability, the treatise remains abstract. However, biographical descriptions of Nider from his contemporaries and the visitation letters he wrote to women's convents show Nider as an engaged liturgical leader, a talented singer with a robust voice, and a zealous expert in the legal particulars of Dominican liturgical regulations. In light of these contexts, De reformatione's sweeping laments over liturgical neglect and academic metaphors of well-disposed proportion are not just rule-hammering and scholastic fancy but rather universalized expressions of Nider's lived commitment to Dominican musical and ritual practice.

多米尼加修道士约翰内斯·尼德（Johannes Nider，1380-1438 年）如今被称为巫术文学之父，他在巴塞尔会议（1431-49 年）中担任胡斯派代表团及其宗教改革代表团的重要角色。尽管尼德被誉为宗教团体改革者，但他对公共礼拜仪式的态度并没有引起密切关注。本文重点介绍他的广泛理论论文《De Reformatione religiosorum》或《De Reformatione status cenobitici》（论宗教国家的改革），其中尼德阐明了改革的哲学概念，即恢复美丽，体现在有序和平衡的比例上。 。为了普遍适用，这篇论文仍然是抽象的。然而，同时代人对尼德的传记描述和他写给女子修道院的探访信显示，尼德是一位敬业的礼仪领袖、一位声音洪亮的才华横溢的歌手，以及多米尼加礼仪法规法律细节的热心专家。鉴于这些背景，《改革报》对礼拜仪式的忽视和学术隐喻的广泛哀叹不仅仅是对规则的锤炼和学术幻想，而是尼德对多米尼加音乐和仪式实践的生活承诺的普遍表达。
