Again the trinity is not a doctrine from ONE text of scripture but rather from the corpus of scripture as a whole, so compelling me to answer the question based on that one text is fallacious.

However Mark's gospel begins with "The gospel of Jesus, the Son of God" and even the story of the conception in Luke records the angel Gabriel saying,

"Luke 1:32,35
[32]He will be great, and will be called the Son of the Highest; and the Lord God will give Him the throne of His father David.

[35]And the angel answered and said to her, “The Holy Spirit will come upon you, and the power of the Highest will overshadow you; therefore, also, that Holy One who is to be born will be called the Son of God."

So even based on the conception, Jesus is explicitly said to be the Son of the Most High, the Son of God.

So God is His Father. Hope this answers your question?
