D&C 20

After describing the duties and assisting of priesthood offices, the Lord instructs -

"...neither teachers nor deacons have authority to baptize, administer the sacrament, or lay on hands;
59 They are, however, to warn, expound, exhort, and teach, and invite all to come unto Christ."  (Doctrine and Covenants | Section 20:58 - 59)

I note then that all priesthood offices are to "warn, expound, exhort, and teach, and invite all to come unto Christ".  I specifically note that we are to invite all to come to Christ which would suggest to me, His ordinances and covenants.  In my mind, that invitation would specifically include the sacrament.
