(John.20:28) Prove a Trinity?

"Jesus did not correct Thomas" That is a reasoning some would like to conclude. But that reasoning has a flaw here is why. In (Matt.(9.32-35) The Pharisees began to say: "It is by the ruler of the demons that he[CHRIST] expels the demons." But Look at the CONTEXT; Jesus does not correct them either.  Now when they were leaving, look! people brought him a dumb man possessed of a demon; 33 and after the demon had been expelled the dumb man spoke. Well, the crowds felt amazement and said: "Never was anything like this seen in Israel." 34 But the Pharisees began to say: "It is by the ruler of the demons that he expels the demons." 35 And Jesus set out on a tour of all the cities and villages, teaching in their synagogues and preaching the good news of the kingdom and curing every sort of disease and every sort of infirmity. Jesus not God; John 20:28; Trinity; Question; Truth; Discussion with Jehovah's Witness! (Judges.13:20,22) (2Cor.4:4) ;whom the god of this system of things has blinded the minds of the unbelievers, (2Cor.4:4) Has the Definite Article.
