The first two chapters of Hebrews deal with the mystery of Christ using the method of comparision (synkrisis). The situation of the glorified Christ is compared with the position and function of the angels. The whole section serves as an introduction into the explanation of the Christ's salvation from the cultic and priestly point of view, which is unique among the New Testament writings. The argumentation of the author of Hebrews is comprehensible against the background of the different concepts of human and angelic priesthood as they are witnessed by the sources of the Second Temple literature. The aim of the present paper is to focus on the function of the first two chapters of Hebrews as an introduction to its main theological theme and to highlight the singularity of the Christian concept of priesthood.
