A pastor preached that trinity is very logical, he said, if god was one person, after incarnation to become man, who will control the universe? Therefore, trinity solves this problem, the Son became flesh, and the Father was still in heaven to control and uphold the universe. Very logic, he said! This is bullsheet! First, let me tell you what is automation. I graduated engineering, worked in factory before, dealt with automated machines like CNC. With microprocessor, sensors, PLC and all sorts of things, a machine can be automated and run on itself without supervision after you have set its settings. You can walked away to do other things and let the machine continue to operate. So, the christians claim that their God is OMNIPOTENT, he can do whatever possible, nothing is impossible with him. We have seen that even the fragile human (compared to the so-called God) can invent and make a machine to run automatically, why not God is able to incarnate as man, at the same time enable the universe to operate on itself? He is omnipotent, can he do that? If can, then trinity is false. If can not, then God is not omnipotent. I read books, talked with christians, until now, no books, no christian can fully explain the trinity logically to me. Some say trinity is like water, can be solid ice, liquid water, and gaseous vapor, after all, it is still H2O. Ha ha, the word trinity is not vividly mentioned in bible, when people thought more about its teaching, inquired about the nature of Jesus, then the council of christianity decided to enact Creed to incorporate trinity into their faith. Just a man-made theory based on the ambiguity of bible.
