Jesus said we are to pray to his God and his Father through him. Paul say there is one mediator between God and man and that one is the man Jesus the anointed one. Further if we pray to God we can use His name Yehovah, and if we pray to God - Yehovah in the name of Jesus, which in the hebrew is Yehoshua. However, what name is given to the holy spirit?
We pray to God the Father, through Jesus Christ the son, by the Holy Spirit!
