I do not have to disprove YOUR assertion of a truth claim. It's up to you. Can you support your claim???
You’re jumping up and down insisting that I disprove a negative.
Not playing.
Prove that Mary the Mother of Christ had other children.
For instance: if she did have other children, perhaps you could begin by listing their names?
And if she did have other children, why did Christ declare from the cross that St John would be her son? What was the point?
