Jesus Christ is described as being in the manner of Melchizedek, (meaning - king of righteousness) namely, as a priest and king.
However, according to JW teachings, when Jesus ascended to heaven he only received 50% of his Melchizedek status, because he had to wait for more than 1800 years (until 1914) before he qualified for the full title.
(Hebrews 3:1) Consequently, holy brothers, partakers of the heavenly calling, consider the apostle and high priest whom we acknowledge—Jesus.
(Hebrews 4:14) Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God..
(Hebrews 5:6) “You are a priest forever in the manner of Melchizedek.”
