This article deals with the issue of the specificity of authority in the Church. The author starts from the biblical and theological premises and then he characterizes its legal canonical aspects. Church authority is derived from Christ and it was transferred by ordination. It is also associated with the authorization of authoritative acts in the field of teaching, sanctifying and governing the People of God as well as it is performed in a manner of service. In accordance with the will of the Church Founder, it is determined as a one authority, although it refers to individual functions and tasks. The 1983 Code of Canon Law, on the basis on the way it was updated, divides church authority into the power of ordination (potestas ordinis) and government (potestas regiminis seu iurisdictionis). The first one is updated by the valid reception of the sacrament of Holy Orders, and the second one by the office or delegation. On the other hand, the church power of government is divided into ordinary (ordinaria) and delegated (delegata) due to the method of updating.
