Kształtowanie się hierarchii duchowieństwa do IV w.

The present article deals with the issue of the formation of the hierarchy of the clergy up to the 4th century. In this century there is already contact with a formed group of clergy, comprising seven degrees of ordination. In the first part of the study, attention was focused on the aspect of the rise and gradation of higher orders, i.e. episcopate, presbyterate and diaconate. The second part presents the formation and organization of the lower classes of the clergy: the ostiariat, the lectorate, the exorcistate, the acolytate and the subdiaconate. Thanks to this, it is possible to observe the parallel formation of both clergy groups, merged into one whole around the 4th century.
