The terms pastor and priest can be used interchangably. I suppose that could be a point where a difference could exist. Old testament priests seem more like church pastors/priests to me. I think the wording need be carefully examined, especially in Aramaic, Hebrew as well as English if one wants to differentiate the two. Pastors or church guides might be implicit in a priesthood of believers, egalitarian format where all rotate in roles perhaps with three ranks of beginner, intermediate and elder. If the church structure is efficient and guided by the Holy Spirit, one does have the presence of the pastoring of the Lord.
All Christians can be pastors and teachers and should learn to do so in a priesthood of believers church structure so they can all be evangelists too in addition to keeping true faith while having the temptation of being the guy on stage removed with all the problems that can cause. There would be little financial temptation for the tired rock and roll performer to become the new performer on the Christian stage, and with voluntary priesthood of believers participation there would be little point in living a duplicitous, hypocritical life as is practical with pew sitting Christians delegating Christian leadership to a stage performer.
Rabbi means ‘teacher’; One can act in the role in a priesthood of believers yet not be called ‘teacher’. That church could have pro-theologians write script content to be read aloud.
Matthew 23:8 “But be not ye called Rabbi: for one is your Master, even Christ; and all ye are brethren. 9 And call no man your father upon the earth: for one is your Father, which is in heaven. 10 Neither be ye called masters: for one is your Master, even Christ. 11 But he that is greatest among you shall be your servant. “
