Double Baptism....
You are baptized into the Aaronic Priesthood through water, just as Christ and Joseph Smith were by John the Baptist, and then into the Melchizedek Priesthood through fire, more commonly known as, baptism of the Holy Spirit. Matthew 3:16-17... God The Father baptized His Son personally then Jesus, in His ascended form baptized Joseph and Oliver following their baptisms by John the Baptist. It is right and proper that it should happen this way in preparation tor the fulfillment of the end time prophecies.
