I know the story and the history, so no, they don't make sense. What does "actually studied the verses" mean? I read them. I did not read the original texts in this case. The fact alone that the trinity is not mentioned and defined by the authors of the Bible themselves shows how spurious the entire concept is. Humans tried to and then did this and used the sentences you mentioned to construct something. You MUST be aware of all the logical deconstructions. Anyway, this is about Koranic facts and not the concept of the trinity in Christianity, so I suggest we go back on topic.
