Pray only to the Lord

The passage at the bottom hits on that.

This office involves the three functions of prophet, priest,
and king, all of which are discharged by Christ both in his
estate of humiliation and exaltation. These functions are so
inherent in the one office that the quality appertaining to each
gives character to every mediatorial act. They are never
separated in the exercise of the office of mediator.
