Yes, Christ was the manifestation of God in the flesh. "In the beginning was the Word, and the Word was with God, and the Word was God.. And the Word was made flesh, and dwelt among us" (John 1; 1&14). Christ responded to the devils temptation with, "Thou shalt not tempt the Lord thy God" (Matthew 4:7). The Father, Son, & Spirit are different aspects expressing one entity, a single Godhead.
"Philip saith unto him, Lord, show us the Father, and it sufficeth us. Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Show us the Father?" (John 14: 8&9)
