This has at least two interpretations: literal, (Jesus concern for his mother who would otherwise be left chhlesss, without support); and symbolic, in the light of the Cana episode in Jn 2 (the presence of the mother of Jesus, the address ‘Woman,’ and the mention of His ‘hour’) Mary (who is also a symbol of the church) is given a role as the mother of the faithful.
There is one interpretation, based on the words the Holy Spirit inspired.
Mary was never given a role as mother of The faithful anywhere in Scripture.
Nor is Mary a symbol of the church anywhere in Scripture.
Since this is not in Scripture, who tells you this stuff?
Since its not in Scripture, why would you believe it??
Revelation 12.
