I will disagree.
You *want* Mary to be your mother.
Never-the-less, God doesn’t make her your mother in Scripture anywhere.
So you are left trying to come up with lines of argument to rationalize your desires.
If it were in any way important, God would have revealed and declared it.
He did not.
He did reveal it when Jesus told John, “Behold your mother” (John 19:27). John’s own biological mother was also present at the time (Matthew 27:56), so evidently Jesus had something other than biology in mind. If it was not important, John would not have drawn attention to it, nor to the other information about Mary unique to his Gospel and Revelation. And I have already quoted numerous other NT passages that discuss spiritual parentage, which is hardly an idea I came up with. “For whoever does the will of my Father in heaven is my brother and sister and mother” (Matthew 12:50)—Jesus’ words, not mine.
