Moroni 3

I would suspect that there may be those of more authority that may question my opinion where Moroni taught -

"THE manner which the disciples, who were called the elders of the church, ordained priests and teachers—
2 After they had prayed unto the Father in the name of Christ, they laid their hands upon them, and said:
3 In the name of Jesus Christ I ordain you to be a priest, (or, if he be a teacher) I ordain you to be a teacher, to preach repentance and remission of sins through Jesus Christ, by the endurance of faith on his name to the end.  Amen.
4 And after this manner did they ordain priests and teachers, according to the gifts and callings of God unto men; and they ordained them by the power of the Holy Ghost, which was in them."  (Book of Mormon | Moroni 3:1 - 4)

I note that in the early days of the restored Church, the word "ordained" was used both in ordaining men to the priesthood as well as what we now differentiate as "setting apart" individuals to callings.

I believe that when Moroni mentioned "priests" (note plural), he is speaking of priesthood ordinations.  I believe that when he mentioned "teachers", he is speaking about Church callings.  I don't believe he is speaking literally of the offices of priest and teaching in the Aaronic priesthood.
