I did not. This is what I said in #44:
This remark shows that you either do not understand how systematic theology is done or deny its legitimacy. Either way, you are wrong.
Systematic theology takes a subject and looks at everything in Scripture that pertains to that subject, regardless of whether passages are "about" that subject, as you and many others understand what it means for a passage to be "about" something.
According to your approach to Scripture, passages that show the deity of Christ but do not have His deity as "the main point" are not teaching "about" His deity. Taking that approach, you would wrongly truncate the biblical evidence for the deity of Christ.
Similarly, you are mistaken in your assertions about my handling of these verses.
What I said is not what you claim I said.
For example, most people say that Matt. 28:18-20 is "about" the Great Commission. Matt. 28:19, however, is not just truth about the Great Commission; it also has truth about the Spirit that is important revelation about the Holy Spirit:
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost"
It does not matter that the passage is not "about" the Holy Spirit. Both New Testament theologies and systematic theologies cite that verse in their theology of the Spirit as one of the texts that shows the deity and full equality of the Spirit with the Father and the Son. That is what I was and am talking about.
