Ah, if Jesus was Mary’s firstborn, who was the second-born, eh? Good point.

That's not how it works. Firstborn is a title with rights and privileges that does not require a second.

That's not how it works. Firstborn is a title with rights and privileges that does not require a second.

I guess that means Jesus is going to be alone in heaven.

That's not how it works. Firstborn is a title with rights and privileges that does not require a second.

Nor does it prohibit another child being born.

Firstborn is a title with rights and privileges that does not require a second.

True; but 2000 years ago, normal folks had LOTS of children: it came with the territory.

Thus, if there is NO 'imperfection' found in Mary (after all; it's been proven that the system works on her side) Catholicism leaves us with two scenarios:

1. Mary purposefully denied Joseph his husbandly 'rights', or...
2. Joseph was shooting blanks.
