This book is consecrated to the Church ministries such as apostles, bishops, presbyters, deacons, prophets, and teachers. Such a question is only historical, but it is very contemporary because in the Church of our times there are several kinds of ministry. Recently, priesthood has been a largely discussed subject. In the context of the Synod of Amazonia (6 -27 October 2019), Pope Francis made an appeal to the Universal Church to reflect and discuss the question of the Church ministries and especially of priests’ or presbyters’ life and ministry. In this sense, the question of Church ministries belongs to main questions of our time. The Post-Synodal Letter was signed on 27 October 2019; there are 33 pages, 5 chapters and 120 paragraphs. Pope Francis approved it and granted permission to publish it in many languages. The question of priesthood and other Church ministries was discussed within the Synodal Way opened by Pope Francis on 9 October 2021 in Rome. This work can be considered a small contribution to the great debate on Christian ministries.
