My goodness, folks, whatever happened to the Bible? The Bible plainly states that Jesus had brothers and sisters (Matthew 12:46,47; 13:55,56; Mark 6:3; John 7:1-10) even going so far as to name them for us. So, what are to make of these passages? I have encountered the following possibilities:
1. They were not actually His brothers and sisters, but were just His cousins since Mary was a virgin and the Greek words could be also translated as cousins.
2. They were Joseph's children and not Mary's and, therefore, only marginally related to Jesus.
3. They were spiritual brothers and sisters, being His disciples.
4. They were actual, biological children of Joseph and Mary and the half-brothers and half-sisters of Jesus Christ.
In response to these interpretations I offer the following:
1. Everywhere in the New Testament the Greek word is consistently translated as brothers and sisters. The statistical likelihood of this being actually cousins is extremely marginal, at best. If they were really cousins, why are there Roman Catholic orders such as the Little Sisters of Jesus and the Brothers of Jesus, but not the Cousins of Jesus? If one were to believe these were His cousins then He would have been comparing His followers not to brothers and sisters, but merely to cousins.
2. If they were only Joseph's children, why do they always appear with Mary and not with Joseph? As has been observed, for them to exist would have meant that Joseph had either married another woman, disobeying God's direct command to him, or that he and Mary had some sort of kinky menage a trois going on.
3. If they were merely His disciples, then the passages would not demarcate them as being distinct persons from His disciples which were present at the same time. It would render these passages utterly meaningless. They become something like this, "Jesus was with His disciples in the house and someone came to Him and told Him that his mother and His disciples were outside of the house, wishing to see him. He then turned to His disciples and told them that they were His mother and His disciples." Duh!
4. It is self-evident and the three positions above are logically, theologically, and biblically flawed to the point where they and entirely implausible, leaving only the obvious conclusion that Jesus actually had half-brothers and half-sisters and Mary and Joseph were their parents.
The primary reason for this great brouhaha about Mary's virginity is that, borrowing from pagan sources, Mary has been given a deistic identity in which sexual intercourse is defined as a mortal sin. Thus, for Mary and Joseph to have engaged in marital relations results in the mistaken belief that, in that manner, she would have shown herself to be a mortal woman.
