"The first Christian on record to claim that Mary had other children was Helvidius."

Jerome (237-420 AD) who was the eminent scholar of his day, considered Helvidius' claim "novel" and shocking. I conclude that he thought of Helvidius' denial of the ever-virginity of Mary as an innovation.

If this is false, then tell me what churchman before Helvidius claimed that Mary, specifically, had other children, or that someone (other than Jesus) was called "son of Mary".

I'll be grateful for a link. I'll follow any link you supply.

Since you have chosen to disbelieve eyewitnesses to the family of Mary and Joseph, you are beyond the truth reaching you catholiciism indoctrinated mind.
