Do you believe that Jesus was the one and only Son of God and that he made that claim? You may have read the following at some time:
“Then the Jews took up stones again to stone him.
Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?”
“The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.”
“Jesus answered them, Is it not written in your law, I said, Ye are gods?”
“If he called them gods, unto whom the word of God came, and the scripture cannot be broken; Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?”
John 10:31-36 King James translation
In the original Koine (“common“) Greek of the New Testament the word “the” in the above translation of “I am the Son of God” simply does not exist. I am not an expert on the language of the New Testament, but I have consulted with some who are. They tell me that generally if a definite article (“the” in grammar) is intended it will be written, but if an indefinite article (like “a“) is intended, it would often be omitted.
Probably a more accurate translation would have been “I am a son of God.”
