What does the Bible say about the priestly office of Jesus Christ?

The priestly office of Jesus Christ is central to the New Testament, particularly in the book of Hebrews. Jesus is portrayed as a High Priest who is not only sinless and eternal, but He is also sympathetic to our human struggles and temptations. Hebrews 4:15 states that He was tempted in every way we are, yet without sin, indicating His unique ability to understand our infirmities and intercede on our behalf. Unlike the Levitical priests, who had to continually offer sacrifices for their own sins, Jesus, as the perfect and eternal High Priest, made a single sacrifice for sins forever (Hebrews 7:27). His priesthood is established after the order of Melchizedek, symbolizing a greater priesthood that does not depend on lineage but rather on His everlasting life and divine authority.
