Let me show you how the disciples felt about this same question.
2 Cor 1:2 "Grace be unto you and peace from God our Father, AND from the Lord Jesus Christ."
same thing said in opening to pretty much every book Paul was credited to have written, look and see.
James 1:1 "James a servant of God AND of the Lord Jesus Christ....."
1Peter 1:3 " Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead."
2 Peter 2:2 " Grace and peace be multiplied unto you through the knowledge of God, AND of Jesus our Lord."
1 John 1:3 ".......and truly our fellowship is with the Father , AND with his Son Jesus Christ."
2 John 1:3 "Grace be with you, mercy, and peace, from God the Father, AND from the Lord Jesus Christ, the Son of the Father, in truth and love."
I believe they make it clear there are 2, God AND his Son.
