The Gospel According to Saint Trinitarian

Assuming the part where Jesus is fully God... 

YHWY, The Most High God, planned and prophesied for Himself to send Himself to Earth as his own son; agreeing with Himself, He volunteered Himself to His self to offer Himself in obedience to His self. Then, He impregnated a woman with Himself in order to become His Son - who was really just Himself - who prayed to Himself and begged Himself not to let Himself be crucified, before finally forsaking Himself and obeying Himself unto death to prove His loyalty to Himself. While dead, He resurrected Himself so that He could return to Himself to sit at His own right hand, and to serve as a mediator between mankind and Himself. With Satan's forces defeated in the end, He turns His kingdom back over to Himself, ruling alongside Himself forever. (Author unknown. Edits by Nathan Lee Lewis)

(And the other Himself, God the Holy Spirit, did stuff too and He, Himself, who is really just the other Selves, is somewhere at the end as well.)
