"the Father, the Father's Name, and the Father's Kingdom"

"the words of the [Lord’s] prayer point out the Father, the Father’s name, and the Father’s kingdom to help us learn from the source himself to honor, to invoke, and to adore the one Trinity.  For the name of God the Father who subsists essentially is the only-begotten Son, and the kingdom of God the Father who subsists essentially is the Holy Spirit.  Indeed, what Matthew here calls the kingdom another evangelist elsewhere calls Holy Spirit:  'May your Holy Spirit come and purify us.'"
