You are incorrect.

No offense, but only a very unwise person would base their theology on the words of Doubting Thomas.
Why?
Oh, that's right... You like to deny Scripture whenever it says something you don't like.
Furthermore, he didn't say "You are God."
Oh yes, here we come with the "it must be these exact words" argument.
Nobody's impressed with your irrational standard.
He basically said, "[You are] my Lord and my God".
Jesus was clear the only true God is the Father (John 17:3)
That doesn't mean that Jesus isn't God.
Once again (something you keep ignoring), "the Father is the only God" is NOT the same thing as "ONLY the Father is God".
therefore Thomas was calling out to the Father or perhaps he was in shock and awe at seeing a hole in Jesus' side and hands. Sometimes even today people say "Oh my God" when they are surprised. Thomas may have been doing that.
And here we come with all the lame excuses for rejecting Scripture.
John 20:28 Thomas answered and said to Him, “My Lord and my God!” 29 Jesus said to him, “Because you have seen Me, have you believed? Blessed are they who did not see, and yet believed.”
Thomas was speaking to Jesus, not to the Father. And he wasn't speaking to Jesus "and" the Father, as it says, "said to HIM (singular)", not "said to "them".
As for claiming he was saying "my God" as an interjection, Jesus would surely have rebuked hiim. But He didn't, He praised him instead.
Matt 16
15“But what about you?” Jesus asked.
“Who do you say I am?”
16Simon Peter answered,
“You are the Christ, the Son of the living God.”
17Jesus replied, “Blessed are you, Simon son of Jonah!
For this was not revealed to you by flesh and blood, but by My Father in heaven.
And here you go, RUNNING AWAY from the passages which prove Jesus is God.
So now that we know Jesus is the Son of the living God and Messiah then we know he isn't God.
Sorry, but that doesn't follow.
That's nothing but worthless rationalization by you designed to deny explicit Scripture.
