Coequality Necessities Within The Trinity

John quotes Jesus as saying:  “I am going to the Father, because the Father is greater than I am” (John 14:28).  Is this coequality within the Trinity?  According to the New Testament, Jesus referred to God as “my God” both before and after his supposed resurrection (Matthew 27:46; John 20:17; Revelation 3:12).  Thus, according to the New Testament, Jesus did not consider himself to be God or God’s coequal, but instead recognized his subservience to God to whom he must go.  As John’s postresurrection Jesus says to Mary Magdalene, “I ascend to my Father and your Father, and my God and your God” (John 20:17).
