Same entity; different persons. Seriously, anyone with 2 cents of knowledge about Trinitarianism would know this. How can you be this ignorant?
How about you deal with Jesus also being "the image of the invisible God, the firstborn of all creation. For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him. And he is before all things, and in him all things hold together." cf Colossian 1:15-17?
If God is a Trinity as you suppose, and given the fact that Christ is the image of the invisible God, then why doesn't he have three heads?
Adam was made in God's image, so why wasn't Adam three persons?
Why is God always the Holy One and not the Holy Three?
Why is the number three NEVER used in scripture in reference to God?
Is Christ in the Godhead or is the Godhead in Christ?
