Jesus was glorifying Mary by saying openly that His mother and brothers were His disciples, not His mother (Mary) and brothers (proving that Mary had intercourse multiple times) who cam to talk Him out of His ministry?
You have a very, very false way of interpreting what the Bible clearly says!!!
Matthew 12:48-49, "But to the one who had told him this, Jesus replied, “Who is my mother, and who are my brothers?” And pointing to his disciples, he said, “Here are my mother and my brothers!"
How do you have the gall to deliberately distort God's word??? The Bible clearly shows that Jesus regarded others as His mother and brothers!!!
And Luke 1:45 has nothing to do with it!
No one was more pure immaculate holy faithful than Mary!
Perpetual virginity is required by the power of the HS who over shadowed her!
Ezekiel 44:2 “This gate shall remain shut; it shall not be opened, and no one shall enter by it; for the Lord, the God of Israel, has entered by it; therefore it shall remain shut.”
Song of Solomon 4:12 A garden inclosed is my sister, my spouse; a spring shut up, a fountain sealed.
Even Luther and Calvin rebuke you
Martin Luther
It is an article of faith that Mary is Mother of the Lord and still a virgin. … Christ, we believe, came forth from a womb left perfectly intact. (Weimer’s The Works of Luther, English translation by Pelikan, Concordia, St. Louis, v. 11, pp. 319-320; v. 6. p. 510.)
John Calvin
(On the Heretic Helvidius) Helvidius displayed excessive ignorance in concluding that Mary must have had many sons, because Christ’s “brothers” are sometimes mentioned. (Harmony of Matthew, Mark and Luke, sec. 39 [Geneva, 1562], vol. 2 / From Calvin’s Commentaries, translated by William Pringle, Grand Rapids, Michigan: Eerdmans, 1949, p.215; on Matthew 13:55)
[On Matt 1:25:] The inference he [Helvidius] drew from it was, that Mary remained a virgin no longer than till her first birth, and that afterwards she had other children by her husband . . . No just and well-grounded inference can be drawn from these words . . . as to what took place after the birth of Christ. He is called “first-born”; but it is for the sole purpose of informing us that he was born of a virgin . . . What took place afterwards the historian does not inform us . . . No man will obstinately keep up the argument, except from an extreme fondness for disputation. (Pringle, ibid., vol. I, p. 107)
Under the word “brethren” the Hebrews include all cousins and other relations, whatever may be the degree of affinity. (Pringle, ibid., vol. I, p. 283 / Commentary on John, [7:3])
John Wesley
‘I believe that He [Jesus] was made man, joining the human nature with the divine in one person; being conceived by the singular operation of the Holy Ghost, and born of the blessed Virgin Mary, who, as well after as before she brought Him forth, continued a pure and unspotted virgin’ (‘Letter to a Roman Catholic’, The Works of Rev. John Wesley, vol 10, p. 81).
And in case you don’t know an article of faith is required for salvation
