The problem with most Christians is they keep trying to place Jesus in a davidic kingship and a levitic priesthood which you cannot combine the two offices. But Jesus’ priesthood is not the earthly levitic priesthood. Jesus’ priesthood is the heavenly melchelzedek order priesthood where you can combine the Kingship And the High Priesthood.

As far as the High Priest needing to be married we know when the 2000 year age of grace through faith in Jesus comes to an end that the dead in Christ and those who have accepted Jesus will meet him in the clouds and these people will be the “Bride of Jesus”

The major problem Christians have is they try to place Jesus on earth during the millennium which is a davidic/levitic kingdom which would make it impossible for Jesus to hold both offices of kingship and high priesthood on earth..If Jesus and the bride are in heaven and the tribulation saints are serving in the throne room as revelation tells us then we have a heavenly melchelzedek order Kingship/High Priesthood ruled by Jesus from heaven. The earthly kingdom then can have messiah ben David ruling the kingship and have messiah Ben Joseph ruling as the earthly high priest as he is from the line of Joseph which is the birthright line 1 chronicles 5:2 qualifying him to be the earthly high priest. Messiah Ben David and Messiah Ben Joseph will be ruling over the reunited northern and southern kingdom and the survivors of armeghedon for the duration of the final 1000 years before the new heaven and new earth are created and Jesus rules over both the Christians and the get lost...with David sitting on his right and Joseph on his left as an eternal reminder of the former earth and the former davidic/levitic kingdom
