The Holy Spirit bears witness to my spirit that Jesus is speaking figuratively there. Since all truth is God's truth, I can claim that. In order to confirm that it was indeed the Spirit bearing witness and helping me to understand that verse, I compare it with other verses. Are there any references in Scripture to Jesus' having a literal daughter? No. Therefore, I am able to deduce, by the God-given mind that I have, that he is speaking of a spiritual/figurative daughter of God. Being Sola Scriptura does not entail interpreting every phrase in the Bible literally. We are aware that the Bible speaks figuratively and poetically at times. The context determines those times. After all, when God says he will hide us in the shadow of His wings, He is not saying that he is a big bird.
On the one hand you claim that "brothers" must mean that Mary had other children when it is clear "brothers" has a different meaning than what you attach to it. And, we have the witness of Church, Ecumenical Councils,and Tradition to back that up.
On the other hand, when Jesus calls a young woman Daughter you say He had no children.
That makes no sense.
I have a Daughter I am a Father. Can I both have a daughter and not be a Father? It appears I can in sola sciptura world
It appears that the real meaning of scripture is simply what you say it is. And there is no scriptual authority for your ownself that you can appeal to. You aint mentioned in the Bible.
Now, why don't you show me where anyone else in the Bible called a young woman Daughter daughter and then maybe we would have something objective to go on. Otherwise, all we got is your personal opinons which, as we have illlustrated repeatedly, are wildly opposed to orthodoxy throughout the ages.
