The problem is also linguistics. Not many know any languages besides English.

Even Spanish is a relatively simplified language, compared to the Greek or Aramaic or Hebrew -- English for instance does not have cases such as Gentive, Nominative, Dative, Locative, Instrumental, Vocative or Accusative and does not have gender assigned to inanimate objects

brother has shades of meaning because Aramaic and other Semitic languages do not differentiate between a blood brother/sister and a cousin or other

For example

1. MAtt 1:2 "Jacob the father of Judah and his brothers," for step-brothers with the same father but different mothers
2. acts 3:17 "17And now, brethren,"
3. Luke 10:29 "and who is my brother"
4. Matt 5:47
5. Matt 23:8
6. Rev 22:9

So, yes, brothers had a wider meaning then just blood brother. And no, the term "Irdu" is not used biblically.

The NT was written in Greek, ok -- not all, but let's take your argument for the sake of argument. Remember also that the words of Jesus were mostly Aramaic or Hebrew or maybe even GReek -- we've already shown that in SEmitic languages like Aramaic/hebrew there is no differntiating term between a blood brother and a cousin, let's examine the GReek ouch outos estin o tekton o uios Marias adelphos de Iakobou Iose kai Iouda kai Simonos

If the term is that the adelphoi have the same mother then it would be ho adelphos But that is not used. Without the article adelphos is non-specific and non-exclusive and can mean kinsmen, relatives

Psalm 69 O God of Israel, 7Because for Thy sake I have borne reproach; Dishonor has covered my face. 8 I have become estranged from my brothers, and an alien to my mothers sons. 9For zeal for Thy house has consumed me, And the reproaches of those who reproach Thee have fallen on me."

Messianic Psalm 69, actually predicts what the NT consistently and matter of factly declares. Jesus had brothers and sisters. John was given responsibility for Mary, because Jesus had "become ESTRANGED from my brothers an ALIEN to my MOTHERS SONS."

I believe the Lord went out of His way to drop hints that Mary should NOT be idolized. IE Luke 11:27 As Jesus was saying these things, a woman in the crowd called out, “Blessed is the mother who gave you birth and nursed you.” 28 He replied, “Blessed rather are those who hear the word of God and obey it.”
