D&C 20

The Lord has declared - 

"...he created man, male and female, after his own image and in his own likeness, created he them;

19 And gave unto them commandments that they should love and serve him, the only living and true God, and that he should be the only being whom they should worship."  (Doctrine and Covenants 20:18–19)

That revelation is interesting..."the only being whom they should worship".  Even the definition of "worship" is interesting - 

"to honor or show reverence for as a divine being or supernatural power...to regard with great or extravagant respect, honor, or devotion"

I believe we are to worship the Father in the name of Jesus Christ...but the Father has instructed us to follow Jesus Christ.  I also belief the scriptures us God for Godhead.  By the very definition of  "worship",  we worship both the Father and the Son.
