Jesus never claimed priestly authority during His earthly ministry. Still, He fulfilled the divine function of a priest. The writer of Hebrews assumes his audience is familiar with Tabernacle/Temple and Levitical priestly duties. In Hebrews, Jesus is identified as the Great High Priest superior to Israel's high priests. The close we consider JEsus' past, present and future ministries the more we appreciate Him and seek to do His will.
