Saint Jerome was a scholar of the five volumes of Saint Hegesippus and he was also the son of Eusebius.
He was no heretic. He didn’t just decide one day that cousins would be called brothers. Everything he wrote was rooted in the writings closest to the apostles.
“He was no heretic. He didn’t just decide one day that cousins would be called brothers. Everything he wrote was rooted in the writings closest to the apostles.”
Then you should have No problem posting a VERY complete bibliography of his EXTENSIVE sources that date to the apostles.
In the meantime, don’t miss that the God who inspired the writings of the Apostles, inspired them to use the Greek word for “brothers” and the Greek word for “sisters” and not to use the Greek word for “cousins”. Three inspired choices that specifically identify that Jesus was not an only child.
