Did Jesus have siblings? Of course. Now, although Jesus Christ was the only begotten Son of God,
he wasn't the only begotten Son of his earthly mother, Mary. In fact, the Bible records her
having other children with Joseph even after the birth of Christ, which is one of the reasons why
we reject the Catholic doctrine of perpetual virginity that teaches that she remained a virgin
even after the birth of Christ. One of the names of his brothers was James, according to Galatians
1.19. And mind you, these are his half-brothers, and like Mary, possess no divinity, nor did they
garner any favor just because they were his kindred. In fact, in Matthew chapter 12 records
an instance where Jesus is preaching to the multitude, his mother and his brethren are
standing without, desiring to speak to him, and he immediately dismisses him, saying,
Who is my mother and who are my brethren? indicating that he would favor God's people
more than his own flesh and blood. There was actually a time when his brothers didn't even
believe that he was the Messiah. John chapter 7 and verse number 4 states,
If thou do these things openly, show thyself to the world, for neither that his brethren believe
in him. Now they would eventually come around and get saved, which is one of the reasons why
James became the pastor of the church in Jerusalem.
