Hello Notch, thanks for responding.

Of course Ehrman believes the title to Matthew was added later. Ehrman believes a lot of things without evidence.
But what matters is the evidence, not Ehrman's opinion.
And the evidence is clear.
Every manuscript of Matthew with an intact title page contains the heading "The Gospel According to Matthew" or "According to Matthew."
Every mention in the early church fathers attributes the Gospel of Matthew to Matthew.
Ehrman has no evidence to stand on.

"You said:
"The Trinity is one God."
I didn't say that.
No, I said that.
I put your words in italics and quotations.
I put my words in non-italicized text, to distinguish them.
The Trinity is one God.
You said:
"That's not the Trinity."
The Father is God, the Son is God, the Holy Spirit is God.

You're halfway there, but you missed a step.
Yes, the Father is God, the Son is God, and the Holy Spirit is God.
But which God are they?
Are they three Gods?
No. They are all the same God.
That's why Jesus says that He and the Father are one -- not two.
You said:
"...your question indicates you haven't studied how widespread belief in the Trinity is."
You have made a very bad assumption. I have been studying Christianity for over 50 years.
I never doubted how long you've studied.
I questioned the material you've studied.
You said:
"They all fail."
For critical thinkers they don't fail.
Then provide one. Let's examine it. Let's apply critical thinking to it and see what happens.
