The article said there were multiple interpretations of the term brother.
From the article:
“James, also known as “James the Just” was a leader of the early church - one interpretation of “brother” may thus be a close spiritual relationship as opposed to a fraternal biological link. The First Apocalypse of James describes James as not Jesus’ brother “materially.””
Blah, blah, blah.
Jesus had brothers. Real life brothers from his mother Mary. Who did not remain a virgin all her life.
