(Jehovah said,) "Contend with your mother...; ...she is not My wife, and I am not her Husband." (Hosea 2:2)

"You are the daughter of your mother, who loathes her Husband...." (Ezekiel 16:45)

"Where is the certificate of your mother's divorce, whom I have put away?" (Isaiah 50:1)

Your mother was like a vine..., planted by the waters, fruitful.... (Ezekiel 19:10)

"Mother" in the those places refers to the Jewish Church.

(Jesus, stretching out His hand toward His disciples, said,) "My mother and My brothers are they who hear the word of God and do it." (Luke 8:21, cf. Matthew 12:48-50, Mark 3:33-35)

The church is meant by the Lord's disciples.

By the cross of Jesus stood His mother.... (And) Jesus...seeing His mother and the disciple whom He loved standing by, (also) said to His mother, "Woman, behold your son!" And He said to the disciple, "Behold your mother!" (Therefore) from that hour the disciple took her into his own [home]. (John 19:25-27)

The meaning here is that the Lord did not acknowledge Mary but the church as His mother. That is why He calls her "woman" and names her the mother of the disciple. He named her the mother of this disciple, John, because John represented the church in respect to its good acts of charity. These good acts are the church in actual practice. Therefore it is said that the disciple took Mary into his own [home]. (We explained in The Apocalypse Revealed that Peter represented truth and faith, James charity, and John works of charity - see nos. 5, 6, 790, 798, 879 - and that the twelve disciples together represented the church in all its elements - see nos. 233, 790 [798?], 903, 915.)
