The teaching of the Catholic Church says that bishops are successors of the apostles, and by extension from that, representatives of the one who sends the same apostles, Jesus Christ. Since the very first centuries the bishops have had a very important role of being presiders of christian communities. In this paper we began from explaining the very term bishop, and what bishop meant in the historical development of the Church. We have set foot on a historical journey from the first centuries when the bishop was the head of small communities, we could say first parishes, over the middle ages when the episcopal office had the summit of its glory, but also its moral decadence, all up until today when bishops are leading large dioceses and are acting in an organized fashion in communion with the Supreme Pontiff, the pope. It is interesting to recognize how the Church Fathers view the importance of a bishop already in the first centuries of christianity. The highlight of historical observation of episcopal office was the Second Vatican Council (1962.-1965.) which dealt with the theology of episcopacy at length. In the second part of the papaer we described the Rite of episcopal ordination, with additional commentary and suggestions. Episcopal ordination is very significant because by it, by the imposition of hands and the consecratory prayer, the apostolic succession, which reaches all up to Christ, is transferred upon the ordinand. In the third and the last part we dealt with the chosen canons of the Code of Canon Law, from the book The People of God in which, by aditional comments, we have commented on the office of bishop in general, his responsibilities, the resignation, election of a new bishop, as well as offices of auxiliary bishops and bishop coadjutor.
