If you're going to argue Christian theology, you have to know something about it. Simply making statements that aren't theologically tenable doesn't prove your "argument."
Believing God has 2 equal partners is polytheism. Jesus himself said that the utter most important commandment is that God is ONE with no OTHERS beside him. One Lord, One deity. Not part of a trinity, does not have equals.
29Jesus answered, “The most important is, ‘
Hear, O Israel, the Lord our God is one Lord,30and you must love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength.’
31The second is this: ‘You must love your neighbor as yourself.’No other commandment is greater than these.”
32Then the scribe told him, “Well said,Teacher! You have told the truth that ‘
God is one, and there is no other besides him.
33To love him with all your heart, with all your understanding, and with all your strength, and to love your neighbor as yourself is more important than all the burnt offerings and sacrifices.”
34When Jesus saw how wisely the man answered, he told him, “You are not far from the kingdom of God.” After that, no one dared to ask him another question.
